Pearl perch (Glaucosoma scapulare) are endemic to the east coast of Australia and have a long history of exploitation. Recent stock assessments indicate that the current rate of fishing mortality is unsustainable in the long term. To better inform the management of the pearl perch stock and to address gaps in our understanding of their reproductive biology, we investigated patterns in gonad development and estimated length- and age-at-maturity and batch fecundity from females collected from southern and central Queensland waters between 2018 and 2022. The mean gonadosomatic index (GSI) varied both temporally and spatially, with maxima in the austral autumn in southern Queensland and in summer in central Queensland, coinciding with sea surface temperatures between 25.26 and 26.32°C. The length- and age-at-maturity of females were 353 mm (fork length, FL) and 4.42 years, respectively, and batch fecundity (B) was correlated to FL such that Ln(B) = 2.45 × Ln(FL) + 3.90. Our results will inform a management strategy to recover the stock to acceptable levels of exploitation.
珍珠鲈鱼是澳大利亚东海岸的特有物种,有着悠久的开发历史。最近的种群评估表明,从长远来看,目前的捕鱼死亡率是不可持续的。为了更好地为珍珠鲈鱼种群的管理提供信息,并解决我们对其生殖生物学理解的差距,我们调查了2018年至2022年间从昆士兰南部和中部水域采集的雌性鲈鱼的性腺发育模式、成熟时的估计长度和年龄以及批量繁殖力。平均性腺体指数(GSI)在时间和空间上都有变化,最大值出现在昆士兰州南部的南秋和昆士兰州中部的夏季,与25.26至26.32°C的海面温度一致。雌性成熟时的长度和年龄为353 mm(叉长,FL)和4.42 年,批量繁殖力(B)与FL相关,因此Ln(B) = 2.45 × Ln(FL) + 3.90.我们的研究结果将为管理策略提供信息,以将库存恢复到可接受的开采水平。

Hypancistrus zebra is a Loricariid endemic to a very limited stretch of the Xingu River and has a high value in the ornamental fish trade. The natural populations have experienced high fishing pressure since the late 80s and were recently impacted by the construction of the third largest hydroelectric dam complex in the world, the Belo Monte Project. Since 2004, it has been considered critically endangered and had its capture and trade forbidden. Even with its capture and trade prohibited since 2004, the species continues to be one of the most trafficked fish in the world. The biometric knowledge of the species is essential for monitoring its natural populations and management in ex situ environments. This work aims to establish the weight-length relationship (WLR) and length-length relationship (LLR) of the species and to evaluate the condition factor (K) of H. zebra rescued from trafficking. The study was conducted at the Laboratório de Aquicultura de Peixes Ornamentais do Xingu from February 2022 to June 2022, estimating the parameters of WLR and LLR of 1165 specimens divided into four simple linear regression (SLR) models: all specimens, only juveniles, only females, and only males. The K of 190 specimens rescued from trafficking by the Brazilian Federal Police was evaluated. The WLRs and LLRs were estimated using SLR. The difference between the allometry coefficients (b) and between the residuals of the models (juveniles, females, and males) was evaluated using the ANOVA significance test. The total length of the species ranged from 1.6 to 9.3 cm. The coefficient of allometry (b) of the WLR of the species is 3.22 and of the LLR is 1.04, demonstrating that H. zebra presents positive allometric growth. The evaluation of the residuals of the models showed differences between ontogenetic stages and between sexes. The development of juveniles is isometric until the first sexual maturation phase and differs in negative allometric for females and positive allometric for males, showing sexual dimorphism in the species. Among the specimens rescued from trafficking, 54.74% were underweight, and 13.16% were under 60% of the expected K value, demonstrating the poor conditions in which these animals are transported by trafficking.
斑马鱼是新谷河流域特有的一种观赏鱼类,具有很高的贸易价值。自80年代末以来,自然种群经历了很高的捕捞压力,最近受到世界第三大水电大坝建设的影响,贝罗蒙特项目。自2004年以来,它被视为极度濒危物种,并被禁止捕获和交易。即使自2004年起禁止捕捞和贸易,该物种仍然是世界上贩运最多的鱼类之一。该物种的生物特征知识对于监测其自然种群和在迁地环境中进行管理至关重要。本研究旨在建立该物种的重量-长度关系(WLR)和长度-长度关系(LLR),并评估被贩运的斑马获救的条件因子(K)。研究于2022年2月至2022年6月在Laboratório de Aquicultura de Peixes Ornamentais do Xingu进行,对1165个标本的WLR和LLR参数进行了估算,并将其分为4种简单线性回归模型:所有标本、仅幼鱼、仅雌性和仅雄性。对巴西联邦警察从贩运中救出的190个标本中的K进行了评估。用单反法估计WLRs和llr。异速生长系数(b)和模型(幼鱼、雌性和雄性)残差之间的差异使用ANOVA显著性检验进行评估。总体长1.6 ~ 9.3 cm。异速生长系数(b)为3.22,异速生长系数为1.04,表明斑马呈正异速生长。模型残差的评估显示个体发育阶段和性别之间存在差异。在第一次性成熟阶段之前,幼鱼的发育是等长的,雌性的负异速生长和雄性的正异速生长不同,显示了物种的两性二态性。在被贩运的动物中,54.74%的动物体重不足,13.16%的动物体重低于预期K值的60%,表明这些动物被贩运的条件很差。

The genetic diversity of Taenioides cirratus was investigated on the basis of mitochondrial cytochrome c oxidase subunit I (COI) and cytochrome b (Cytb) gene sequences. A total of 159 specimens collected from the Chaohu Lake (CL), Nansihu Lake (NL), Taihu Lake (TL), Pearl River (PR), and Nandu River (NR) were sequenced. The total length of the sequence was 2485 bp with 412 polymorphic sites. A total of 73 haplotypes were identified, with Hap1 being the most widely distributed. The PR and NR populations showed high genetic diversity, while the CL population showed low genetic diversity. TL and NL showed high haplotype diversity but low nucleotide diversity. The analysis of molecular variance demonstrated that the sequence variations were mainly occurred among populations. T. cirratus populations are declining, and rare alleles are present at low frequencies, as analysed using a neutral test and a mismatched distribution analysis. There was a relatively high level of genetic differentiation among the populations of the Yangtze River basin (including NL), PR, and NR (Fst > 0.15). The two similar phylogenetic trees constructed by the maximum likelihood (ML) and Bayesian inference (BI) methods presented three major lineages, of which lineage II contains haplotypes from PR and NR, lineage III contains haplotypes from CL, NL, TL, and PR, whereas lineage I contains only a portion of haplotypes from NR. Based on the neutral test, mismatch analysis, and Bayesian Skyline Plot (BSP), geological and climatic events were inferred to have played an important role in the historical dynamics of T. cirratus population. Hap1, Hap25, and Hap58 were inferred as possible ancestral haplotypes by network analysis. Our study offers an essential foundation for resource preservation and additional taxonomic clarification of T. cirratus.
以线粒体细胞色素c氧化酶亚基I(COI)和细胞色素b(Cytb)基因序列为基础,研究了卷带绦虫的遗传多样性。对从巢湖(CL)、南四湖(NL)、太湖(TL)、珠江(PR)和南渡河(NR)采集的159个标本进行了测序。序列的总长度为2485 bp,多态位点412个。共鉴定出73个单倍型,其中Hap1是分布最广泛的。PR和NR群体表现出较高的遗传多样性,而CL群体表现出较低的遗传多样度。TL和NL表现出较高的单倍型多样性,但核苷酸多样性较低。分子变异分析表明,序列变异主要发生在群体间。根据中性测试和不匹配分布分析的分析,卷层虫的种群数量正在下降,稀有等位基因的出现频率较低。长江流域种群(包括NL)、PR和NR之间存在较高水平的遗传分化(Fst > 0.15)。通过最大似然(ML)和贝叶斯推断(BI)方法构建的两个相似的系统发育树提供了三个主要谱系,其中谱系II包含PR和NR的单倍型,谱系III包含CL、NL、TL和PR的单倍子,而谱系I仅包含NR的一部分单倍型,和贝叶斯天际线图(BSP),推断地质和气候事件在卷层虫种群的历史动态中起着重要作用。通过网络分析推断出Hap1、Hap25和Hap58可能是祖先单倍型。我们的研究为卷层虫的资源保护和进一步的分类学澄清提供了重要的基础。

The study provides the length-weight relationships (LWRs) for eight fish species, viz. Hemiculter bleekeri, H. leucisculus, Opsariichthys bidens (Xenocyprididae), Carassius auratus, Cyprinus carpio (Cyprinidae), Pseudorasbora parva (Gobionidae), Acanthorhodeus chankaensis, and Rhodeus ocellatus (Acheilognathidae), in the world’s largest water diversion project, namely, the middle route of South-to-North Water Diversion Project (SNWDP). Fish specimens were sampled by benthic fyke-nets, gillnets, multimesh gillnets, and electrofishing equipment seasonally from 2015 to 2020. The coefficient of determination (r2) was ranging from 0.964 (R. ocellatus) to 0.986 (H. leucisculus), and the b values for the eight species were within range of 2.5–3.5. Also, our study updates the information on the maximum total length for four species (H. bleekeri, H. leucisculus, A. chankaensis, and O. bidens).

Estimation of the heritability for a given phenotype would provide basic information for potential breeding programs. As one of the most precious common carp strains, Yellow River carp was subject to selection for fast growth and a slender body to meet market demands. In the present study, heritabilities for body shape (body length, BL and body height, BH) and body weight (BW) were estimated based on a molecular parentage assignment for 750 progenies from 58 half-sib and full-sib Yellow River carp families. Eight highly polymorphic microsatellites were used for the construction of the molecular pedigree, and the average observed heterozygosity (Ho), expected heterozygosity (He), and the polymorphism information content (PIC) were 0.841, 0.792, and 0.763, respectively. All 750 progenies were successfully assigned to single parental pairs with 100% accuracy. Using the linear mixed model, the heritabilities were estimated to be 0.268, 0.338, and 0.340 for BL, BH, and BW, respectively. High phenotypic (0.831–0.927) and genetic (0.952–0.987) correlations among these three traits suggested that selection for BW could also largely affect the body shape and vice versa. Moderate heritabilities and high genetic corrections revealed by this study strongly indicate substantial potentials for genetic improvement of both growth rate and body formation in Yellow River carp breeding programs.
对给定表型的遗传力的估计将为潜在的育种计划提供基本信息。黄河鲤鱼是我国最珍贵的鲤鱼品种之一,为满足市场需求,选用生长快、体细的品种。在本研究中,基于来自58个半同胞和全同胞黄河鲤鱼家族的750个后代的分子亲本分配,估计了体型(体长、BL和身高、BH)和体重(BW)的遗传力。使用8个高度多态性的微卫星构建分子家系,平均观察杂合度(Ho)、预期杂合性(He)和多态性信息含量(PIC)分别为0.841、0.792和0.763。所有750个后代都以100%的准确率成功地分配到单亲配对中。使用线性混合模型,BL、BH和BW的遗传力分别估计为0.268、0.338和0.340。这三个性状之间的高表型(0.831-0.927)和遗传(0.952-0.987)相关性表明,对BW的选择也可能在很大程度上影响体型,反之亦然。本研究所揭示的中等遗传力和高遗传校正有力地表明,在黄河鲤鱼育种计划中,生长速度和体型的遗传改良具有巨大的潜力。

Validation of the Use of Otoliths to Estimate Age and Growth of Larval Lake Whitefish, Coregonus clupeaformis 利用耳石估算湖白鱼幼鱼年龄和生长的验证

Understanding drivers of recruitment variation in fish populations requires research conducted on early life stages. Examination of fish otoliths provides useful information for estimating hatching dates, growth, and survival rates of larvae and for investigating the relationship between early life stage phenology and variation in environmental factors such as climate and food availability. In the Laurentian (i.e., North American) Great Lakes, significant reductions in the number of young (ages 1–4 years) lake whitefish (Coregonus clupeaformis) recruiting into the population and commercial fishery have raised questions about factors affecting growth and survival of the larval life stage. Here, we investigate the utility of using otoliths to estimate the age and growth of larval lake whitefish. We raised offspring of wild-caught parents from Lake Simcoe (Ontario, Canada) in a hatchery environment and analyzed otoliths of these known age fish for 75 days posthatch. We further examined otoliths of wild-sampled larvae and age 0 lake whitefish from Lake Huron. We found a strong linear relationship between known age and number of postcheck increments on the otolith and between growth of the otolith and fish length. Increments formed at nearly 1 (0.9) per day beginning at day 20 after hatch. Check and subsequent increment formation was associated with disappearance of the yolk sac. Wild fish had more prominent checkmarks and grew slower than hatchery fish. Thus, otolith analysis represents a promising tool to examine dynamics of early life stages of lake whitefish, although further research is required on the effects of environmental conditions on otolith microstructure.
了解鱼类种群中招募变化的驱动因素需要对生命早期阶段进行研究。对鱼耳石的检查可以提供有用的信息,用于估计幼虫的孵化日期、生长和存活率,以及研究生命早期物候与气候和食物供应等环境因素变化之间的关系。在劳伦森(即北美)五大湖,幼鱼(年龄1-4岁)湖泊白鱼(Coregonus clupeaformis)加入种群和商业渔业的数量显著减少,引起了对影响幼虫生命阶段生长和存活的因素的质疑。在这里,我们研究了利用耳石来估计幼湖白鱼的年龄和生长的效用。我们将来自加拿大安大略省西姆科湖(Lake Simcoe)的野生捕捞鱼的后代饲养在孵化场环境中,并对这些已知年龄的鱼的耳石进行了75天的分析。我们进一步检测了休伦湖野生幼鱼和0岁湖白鱼的耳石。我们发现已知年龄与耳石的后检增量数量之间以及耳石的生长与鱼的长度之间存在很强的线性关系。从孵化后第20天开始,以每天近1(0.9)的速度增加。检查和随后的增量形成与卵黄囊的消失有关。野生鱼比孵化场的鱼有更多的突出的标记和生长速度慢。因此,尽管环境条件对耳石微观结构的影响还有待进一步研究,但耳石分析是研究湖白鱼早期生命阶段动态的一种很有前途的工具。

Examination of fish otoliths provides useful information for estimating hatching dates, growth, and survival rates of larvae and for investigating the relationship between early life stage phenology and variation in environmental factors such as climate and food availability. In the Laurentian (i.e., North American) Great Lakes, significant reductions in the number of young (ages 1–4 years) lake whitefish (Coregonus clupeaformis) recruiting into the population and commercial fishery have raised questions about factors affecting growth and survival of the larval life stage. Here, we investigate the utility of using otoliths to estimate the age and growth of larval lake whitefish. We raised offspring of wild-caught parents from Lake Simcoe (Ontario, Canada) in a hatchery environment and analyzed otoliths of these known age fish for 75 days posthatch. We further examined otoliths of wild-sampled larvae and age 0 lake whitefish from Lake Huron. We found a strong linear relationship between known age and number of postcheck increments on the otolith and between growth of the otolith and fish length. Increments formed at nearly 1 (0.9) per day beginning at day 20 after hatch. Check and subsequent increment formation was associated with disappearance of the yolk sac. Wild fish had more prominent checkmarks and grew slower than hatchery fish.

Thiamine is a crucial nutrient in larval stage of fish, and thus, the present study aimed at evaluating the effects of dietary thiamine supplementation on survival, growth performance, and biochemical parameters of beluga, Huso huso, larvae. The fish larvae (50 ± 4.5 mg) were fed diets containing 0 (control), 5, 10, and 20 mg/kg thiamine for 26 days from 18 days after hatching to 44 days after hatching. Thiamine significantly increased the larvae survival, growth rate, digestive enzymes activity, and whole body protein and ash but decreased the whole body lipid and moisture P < 0.001 ). Also, alanine amino transferase (ALT) and alkaline phosphatase (ALP) were decreased significantly in thiamine-treated groups ( P < 0.05 ). The highest survival and whole body ash were observed in 20 mg/kg thiamine treatment; the highest whole body protein and lipase activity were observed in 10 mg/kg thiamine treatment. The highest growth rate, amylase, and lowest whole body lipid, alanine amino transferase (ALT), and alkaline phosphatase (ALP) were observed in 10 and 20 mg/kg thiamine treatments. All thiamine-treated fish exhibited similar pepsin and chymotrypsin activities, all above the control fish. There were no significant effects of dietary thiamine supplementation on trypsin, whole body lysozyme, alternative complement (ACH50), lactate dehydrogenase (LDH) activities, and IgM levels. According to the results, 10–20 mg/kg dietary thiamine supplementation can increase the performance of beluga larvae by improving the health of liver and the activity of digestive system.
硫胺素是鱼类幼虫期的重要营养素,因此,本研究旨在评估日粮中补充硫胺素对白鲸、胡索、幼虫生存、生长性能和生化参数的影响。鱼的幼虫(50 ± 4.5 mg)喂食含有0(对照)、5、10和20 mg/kg硫胺素26 18天后 孵化后至44天 孵化后几天。硫胺素显著提高幼虫的存活率、生长速度、消化酶活性、全身蛋白质和灰分,但降低了全身脂质和水分(P<0.001)。硫胺素治疗组丙氨酸氨基转移酶(ALT)和碱性磷酸酶(ALP)显著降低(P<0.05)。存活率和全身灰分最高的是20 mg/kg硫胺素处理;在10个个体中观察到最高的全身蛋白质和脂肪酶活性 mg/kg硫胺素处理。10和20岁的婴儿生长速度最高,淀粉酶最高,全身脂质、丙氨酸氨基转移酶(ALT)和碱性磷酸酶(ALP)最低 mg/kg硫胺素处理。所有硫胺素处理的鱼都表现出相似的胃蛋白酶和糜蛋白酶活性,均高于对照鱼。日粮中补充硫胺素对胰蛋白酶、全身溶菌酶、替代补体(ACH50)、乳酸脱氢酶(LDH)活性和IgM水平没有显著影响。根据结果,10-20 日粮中添加硫胺素mg/kg可通过改善肝脏健康和消化系统活性来提高白鲸幼虫的生产性能。

During multiple annual spawning runs from 2013 to 2021, over 9,000 mature anadromous alewife (Alosa pseudoharengus A. Wilson, 1811) were monitored with passive integrated transponders (PITs) in four rivers of the Chignecto Isthmus, Bay of Fundy, Canada. A subsample of 384 individuals tagged during 2016–2019 were aged from 3 to 6 years (mean ± SD; 4.2 ± 0.7 years, n = 232, males; 4.5 ± 0.7 years, n = 152, females). Biotelemetry revealed that one unsexed individual survived seven years post tagging, possibly making it 10–13 years old. Return rates varied among the rivers, with the lowest rates in the most anthropogenically impacted river. Biotelemetry and ageing data were used to estimate apparent annual survival rates ranging from 0.25 to 0.50 depending on the river and the year. Based on capture-mark-recapture (CMR) analysis of biotelemetry data from the three less impacted rivers, the estimated overall annual survival was 0.396, total instantaneous mortality (Z) was 0.93, and future life expectancy from time of release was 1.08 years. Frequency distribution of ages 4–6 for alewife pooled from all four study rivers estimated a lower annual survival rate of 0.301, Z = 1.20, and a future life expectancy of 0.83 years. The biotelemetry detection rates were 0.89–0.98 but varied depending on the river and the year, with the lowest rates in one river during 2017-2018 possibly related to a malfunctioning tide gate preventing upstream fish passage and subsequent detection. Based on CMR, males had a higher survival rate compared to females, which translated into an overall mean survival increase of 0.05. Alewife survivorship in our study highlighted that a limited ecosystem-based management period is required to mitigate river connectivity and mortality issues to avoid loss of population cohorts and decrease the risk of extirpation.
在2013年至2021年的多次年度产卵过程中,在加拿大芬迪湾Chignecto地峡的四条河流中,使用无源集成转发器(PIT)监测了9000多条成熟的溯河产卵alewife(Alosa pseudoharengus A.Wilson,1811)。2016年至2019年期间,384名被标记的个体的子样本年龄在3至6岁之间(平均 ± SD;4.2 ± 0.7 年,n = 232,男性;4.5 ± 0.7 年,n = 152,女性)。生物遥测显示,一个未固定的个体在标记后存活了7年,可能达到10-13岁 岁不同河流的回报率各不相同,受人类影响最严重的河流回报率最低。根据河流和年份的不同,使用生物遥测和老化数据来估计表观年生存率在0.25至0.50之间。根据对三条受影响较小河流的生物遥测数据的捕获标记再捕获(CMR)分析,估计的年总生存率为0.396,瞬时总死亡率(Z)为0.93,从放生时起的未来预期寿命为1.08 年。从所有四条研究河流中收集的4至6岁的阿列韦的频率分布估计,较低的年生存率为0.301,Z = 1.20,未来预期寿命为0.83 年。生物遥测检测率为0.89–0.98,但因河流和年份而异,2017-2018年期间一条河流的最低检测率可能与阻止上游鱼类通过的潮汐闸门故障和随后的检测有关。根据CMR,男性的存活率高于女性,这意味着总体平均存活率增加了0.05。Alewife在我们的研究中强调,需要有限的基于生态系统的管理期来缓解河流连通性和死亡率问题,以避免种群群的损失并降低灭绝风险。

Body colors are an important trait for the survival and reproduction of animals. In this study, transcriptomes and related single nucleotide polymorphisms (SNPs) of black- and red-colored Plectropomus leopardus (Lacépède) were identified to investigate important molecules and SNP markers associated with body color formation. In the comparison of red- and black-colored groups, 489 differential expressed genes (DEGs) were detected and among them, 236 up- and 253 down-regulated genes were found in the red-colored group. Gene ontology (GO) analysis of DEGs showed that pigmentation associated terms including pigment granule, pigmentation, melanin metabolic process, tyrosine metabolic process, pigment metabolic process, and pigmentation cell differentiation were enriched. Kyoto encyclopedia of genes and genomes (KEGG) analysis of DEGs presented that melanin related pathways (tyrosine metabolism and melanogenesis) were enriched. Furthermore, lipid metabolism and immune-related metabolism were also enriched. A total of 1,048,575 SNPs were detected from the transcriptome, and among them, 627,172 SNPs were located in the gene region. A total of 1323 SNPs were identified as differential SNPs in the comparison of black- and red-colored groups and were located in 1127 genes. Among the 1127 genes, 20 genes were identified as DEGs and were comprised of 9 SNPs with a potential role in body color selective breeding in fish farming.
体色是动物生存和繁殖的重要特征。在本研究中,鉴定了黑色和红色豹子(Lacépède)的转录组和相关单核苷酸多态性(SNPs),以研究与体色形成相关的重要分子和SNP标记。在红色和黑色组的比较中,检测到489个差异表达基因(DEG),其中,在红色组中发现236个上调基因和253个下调基因。DEG的基因本体论分析表明,色素颗粒、色素沉着、黑色素代谢过程、酪氨酸代谢过程、色素代谢过程和色素沉着细胞分化等色素沉着相关术语丰富。京都基因和基因组百科全书(KEGG)对DEG的分析表明,黑色素相关途径(酪氨酸代谢和黑色素生成)得到了丰富。此外,脂质代谢和免疫相关代谢也得到了丰富。从转录组中共检测到1048575个SNPs,其中627172个SNPs位于基因区。在黑色和红色组的比较中,共有1323个SNPs被鉴定为差异SNPs,位于1127个基因中。在1127个基因中,有20个基因被鉴定为DEG,由9个SNPs组成,在鱼类养殖的体色选择育种中具有潜在作用。

Acentrogobius virgatulus (Jordan & Snyder, 1901) is a small coastal species of goby found along the Western Pacific. It is commonly found in Maizuru bay along the muddy sediment between the intertidal zone and depths of 10 m. In June and July of 2022, two independent agonistic interactions between male A. virgatulus were observed and recorded during its spawning season. One interaction, lasting over 4 minutes, included certain aggressive behaviors such as jaw locking, mouth gaping, fin extensions, rapid color changes, and fast strikes to the head and body. Another interaction exhibited similar mouth gaping, fin extension, and rapid color changes but did not lead to further escalation. These behaviors coincide with those found in similar species and provides in situ evidence of these uncommon interactions. This is the first record of agonistic behavior by an Acentrogobius species. Accumulating findings such as these can contextualize intraspecific interactions, reveal differences across multiple species, and guide future experiments.
Acentrogobius virgatulus (Jordan & Snyder, 1901)是沿西太平洋发现的一种小型沿海虾虎鱼。它常见于舞足湾,沿着潮间带和深度10米之间的泥泞沉积物。在2022年6月和7月,观察和记录了两次独立的雌雄互作。其中一次互动持续了4分钟以上,包括某些攻击性行为,如颌锁、张口、鳍展、快速变色以及对头部和身体的快速攻击。另一种相互作用表现出类似的张口,鳍延伸和快速颜色变化,但不会导致进一步升级。这些行为与在类似物种中发现的行为一致,并为这些不常见的相互作用提供了原位证据。这是第一次记录了一种无尾虾的竞争行为。积累这些发现可以将种内相互作用的背景化,揭示多个物种之间的差异,并指导未来的实验。
