This study investigated the well-being and survival of larvae of the blue crab, Callinectes sapidus, under the influence of several abiotic and biotic factors, in order to collect relevant data for optimizing the larval period in the culture of this species. Aspects tested and examined were primarily: water volume, stocking density, salinity, (frequency of) moulting, starvation, mortality, cannibalism, behavioural aspects (e.g., mobility, intraspecific aggression), larval development, as well as the influence of ground colours. All aspects appeared to influence the duration and success of the larval period, from zoea-I to megalopa, but the main difference was observed to be related to the (water) volume of the culture tanks.
这项研究调查了蓝蟹(Callinectes sapidus)幼体在若干非生物和生物因素影响下的健康和存活情况,以便收集相关数据,优化该物种的幼体养殖期。测试和研究的方面主要包括:水量、放养密度、盐度、(换羽频率)、饥饿、死亡率、食人、行为方面(如流动性、种内攻击)、幼体发育以及地面颜色的影响。所有方面似乎都会影响幼虫期的持续时间和成功率,从第一代幼虫到巨虫,但观察到的主要差异与养殖池的(水)容量有关。

Lobsters and crayfishes have social, economic and ecological significance in several regions around the world. These crustaceans have complex digestive systems and open circulatory systems colonized by symbiotic microorganisms that play essential roles in the health, nutrition and disease of crustaceans, attracting considerable interest. The importance of the microbiota for the successful cultivation of animals in captivity is known, however, there is a lack of information about the symbiotic microbiota in different species of lobsters. The aim of this study was to summarize global information on microbiota studies of anatomical sites of lobsters and crayfishes looking for patterns of bacteria that colonize their intestine, hepatopancreas and haemolymph. A systematic review was conducted using “Methodi Ordinatio”. Twenty-five significant articles, from 12 countries, were identified for analysis from the Scopus database. The crustacean genera found were Cherax, Pacifastacus and Procambarus (crayfish); Homarus, Nephrops and Panulirus (lobsters). The intestinal, hepatopancreas and haemolymph microbiota show a wide variety of bacteria influenced by infections affecting the individual, stress caused by changes in the environment, availability and quality of food, period of the year, stage of development and the animal’s sex, among other aspects. The common core bacterial microbiota among crustaceans consist of the genera Acinetobacter, Aeromonas, Candidatus Bacilloplasma, Candidatus Hepatoplasma, Citrobacter, Hafnia, Photobacterium, Pseudomonas, Shewanella and Vibrio. The results broadened our understanding of the microbiota in the intestinal and circulatory systems of crustaceans, the flaws for and needs for standardization of analysis techniques, and the use of a multi-specialized approach for the protection and management of lobsters as a fisheries resource.
龙虾和小龙虾在全球多个地区具有重要的社会、经济和生态意义。这些甲壳类动物拥有复杂的消化系统和开放的循环系统,共生微生物在甲壳类动物的健康、营养和疾病方面发挥着至关重要的作用,引起了人们的极大兴趣。众所周知,微生物群对成功圈养动物非常重要,然而,有关不同种类龙虾共生微生物群的信息却十分匮乏。本研究的目的是总结全球有关龙虾和小龙虾解剖部位微生物群研究的信息,寻找其肠道、肝胰腺和血液淋巴中定植细菌的模式。我们使用 "Methodi Ordinatio "进行了系统回顾。从 Scopus 数据库中找到了来自 12 个国家的 25 篇重要文章进行分析。发现的甲壳动物属有 Cherax、Pacifastacus 和 Procambarus(小龙虾);Homarus、Nephrops 和 Panulirus(龙虾)。肠道、肝胰腺和血液淋巴微生物群中的细菌种类繁多,受个体感染、环境变化造成的压力、食物的可获得性和质量、年份、发育阶段和动物性别等多方面因素的影响。甲壳类常见的核心细菌微生物群包括醋杆菌属、气单胞菌属、棒状杆菌属、肝原体属、柠檬酸杆菌属、哈夫尼亚属、光杆菌属、假单胞菌属、雪旺菌属和弧菌属。研究结果拓宽了我们对甲壳类动物肠道和循环系统微生物群、分析技术标准化的缺陷和需求以及使用多专业方法保护和管理作为渔业资源的龙虾的认识。

A single male specimen of the pebble crab, Liagore rubromaculata (De Haan, 1835) measuring 40.0 × 27.0 mm (CW × CL) was observed and is recorded for the first time from the west coast of India. The species was identified by the presence of a smooth and unarmed anterolateral margin. Globally, the species has been reported from the waters of Australia, South China, Indonesia, the Persian Gulf, and the Bay of Bengal, but no report is available from the Arabian Sea. Hence the present study bestows the first confirmed record of L. rubromaculata from the Arabian Sea along the west coast of India, provided with a detailed taxonomic description of the species.
观察到卵石蟹 Liagore rubromaculata(De Haan,1835 年)的单个雄性标本,尺寸为 40.0 × 27.0 毫米(CW × CL),这是印度西海岸的首次记录。该物种因其前侧缘光滑无刺而被识别。在全球范围内,澳大利亚、华南、印度尼西亚、波斯湾和孟加拉湾水域都有该物种的报道,但阿拉伯海却没有任何报道。因此,本研究首次证实了印度西海岸阿拉伯海的 L. rubromaculata,并对该物种进行了详细的分类描述。

The pea crab, Pinnotheres onychodactylus Tesch, 1918, is only known on the basis of the types collected from the Moluccas, Indonesia. A re-examination of the type specimens shows that the species is actually a junior subjective synonym of Magnotheres globosus (Hombron & Jacquinot, 1846), a widely distributed Indo-West Pacific species associated with horse mussels of the family Pinnidae.

The type of the poorly known pilumnid crab, Speocarcinus celebensis Tesch, 1918, is redescribed and figured. As Speocarcinus is now known to be a wholly American pseudorhombilid, the generic placement of this Tesch species has been in doubt. Ng (1987) provisionally assigned it to Viaderiana Ward, 1942, but Števčić (2011) decided to place it in a new monotypic genus, Bossacarcinus. The type is a poorly preserved subadult female, and not a male as originally reported. Bossacarcinus celebensis is likely to be a pilumnine, not a rhizopine, and is compared with allied genera like Viaderiana, Ser Rathbun, 1931, Heteropilumnus De Man, 1895, and Xestopilumnus Ng & Dai, 1996.
对鲜为人知的梭子蟹 Speocarcinus celebensis Tesch, 1918 的模式进行了重新描述和图解。由于 Speocarcinus 现在被认为是一种完全属于美洲的假虹彩蝶类,因此该 Tesch 种的属种定位一直存在疑问。Ng(1987 年)暂时将其归入 Viaderiana Ward,1942 年,但 Števčić (2011 年)决定将其归入一个新的单型属 Bossacarcinus。模式标本是一只保存较差的亚成体雌性,而非最初报告的雄性。Bossacarcinus celebensis 很可能是一种柱栖类,而非根栖类,并与 Viaderiana、Ser Rathbun, 1931、Heteropilumnus De Man, 1895 以及 Xestopilumnus Ng & Dai, 1996 等盟属进行了比较。

A new species of deep-sea shrimp, Bathypalaemonella liui sp. nov., is described from the seamount of the South China Sea at a depth of 759–1117 m. Bathypalaemonella liui sp. nov. is most similar to B. hayashi Komai, 1995 and B. serratipalma Pequegnat, 1970 for the flexor margin of the major second pereopod bearing a row of tubercles. Important morphological characters which differentiate the present new species from B. hayashi and B. serratipalma are the length of the rostrum, which is far exceeding the scaphocerite, and the dactylus of the posterior three pereopods, which only bear one pair of accessory spines. Moreover, the genetic divergences of the COI and 16S rRNA genes from these two congeners analysed, clearly support the new taxon.
Bathypalaemonella liui sp.nov.与 B. hayashi Komai, 1995 和 B. serratipalma Pequegnat, 1970 最为相似,其主要的第二节脊椎动物的屈肢边缘有一排小瘤。将本新种与 B. hayashi 和 B. serratipalma 区分开来的重要形态特征是喙的长度,它远远超过了胛骨,以及后三个脚足的双足,它们只带有一对附属棘。此外,所分析的这两个同源种的 COI 和 16S rRNA 基因的遗传差异也明确支持这一新分类群。

Existing studies on central Chilean inland waters only mention records of decapods, but there are no ecological studies about decapods and other crustacean groups. The aim of the present study was a first characterization of inland water crustaceans in Claro River, a Mediterranean-climate river from Chile. The results of redundance analysis (RDA) revealed that the crab Aegla affinis inhabits waters of high pH and low temperature values, whereas amphipods of the genus Hyalella inhabit habitats with high pH, high temperatures, and low values of dissolved oxygen. Finally, ostracods (family Cyprididae), isopods (Heterias sp.) and the southern river crayfish (Samastacus spinifrons) inhabit water systems with moderate values of pH, temperature, dissolved oxygen, and conductivity. This paper represents the first ecological report for crustaceans of central Chilean inland waters, and the results appear to be similar to comparable descriptions for northern Patagonian rivers.
关于智利中部内陆水域的现有研究只提到了十足目动物的记录,但没有关于十足目动物和其他甲壳类动物的生态学研究。本研究的目的是首次描述智利地中海气候河流克拉罗河(Claro River)内陆水域甲壳类动物的特征。冗余分析(RDA)结果表明,蟹类 Aegla affinis 栖息于 pH 值高、温度值低的水域,而片脚类 Hyalella 属栖息于 pH 值高、温度高、溶氧值低的生境。最后,桡足类(鲤形目)、等足类(Heterias sp.)和南方河螯虾(Samastacus spinifrons)栖息在 pH 值、温度、溶解氧和电导率适中的水系中。本文是智利中部内陆水域甲壳类动物的第一份生态报告,其结果似乎与巴塔哥尼亚北部河流的类似描述相似。

The aim of this study is to determine the effect of different stocking volumes on the survival and growth of broodstocks of the blue crab, Callinectes sapidus. Based on a Pearson correlation test, 0.70 litre tanks with three groups at different stocking densities (15, 10 and 5 individuals per tank) have been used in this study. The results show that the mortality rate due to cannibalism was high in the first test group, while it was found to be lower in the third group. There were significant differences in survival rates in the three different groups used in this trial of broodstock cultivation (). The higher the stocking densities, the lower the survival rates, i.e., significantly increasing the broodstock density reduces the survival rate.Statistical differences have also been found in the development rates of broodstock crabs (), and it has been noted that there is slower development at higher stocking densities. If calculating the optimal stock density for mass production purposes is desired, less density thus appears to be more advantageous for both survival and growth rate.
本研究的目的是确定不同放养量对青蟹(Callinectes sapidus)育雏存活和生长的影响。根据皮尔逊相关性测试,本研究使用了 0.70 升的水箱,按不同的放养密度(每箱 15 只、10 只和 5 只)分为三组。结果表明,第一试验组因食人导致的死亡率较高,而第三组的死亡率较低。在本次育雏试验中使用的三个不同组别中,存活率存在明显差异()。放养密度越高,成活率越低,也就是说,大幅提高育苗密度会降低成活率。在育苗蟹的发育速度方面也发现了统计差异(),并注意到放养密度越高,发育速度越慢。如果要计算用于大规模生产的最佳放养密度,较低的密度似乎对存活率和生长率都更有利。
