Highlight Reseacrh The study showed that the selected F-4 blue tilapia had a better growth pattern than the control (non-selection) F-4 blue tilapia The difference in performance between the two populations of blue tilapia is an illustration of the genetic improvement that is passed on from parents to offspring as a result of the selective breeding The realized heritability value of the weight character of F-4 blue tilapia in the high category There was an increase in growth in the F-4 blue tilapia population with a positive response to selection Abstract Breeding program in order to increase genetic improvement in blue tilapia have not been widely carried out at brackish water ponds. This study aimed to evaluate the increase in growth and genetic gain of F-4 blue tilapia from family selection in ponds with 25-30 gL-1 salinity. The parent used for the formation of F-4 is the selected parent F-3 and as a control using the non-selected parent F-3. Spawning was carried out in a full-sib mating design using the family selection method. The ratio of male and female broodstock is 1: 2. Spawning and nursery activities of F-4 blue tilapia are carried out in freshwater. The enlargement test was carried out in the net cage 5m x2.5m x1 m which was installed in the ponds with a salinity of 25-35 g l-1 for 120 days, at a stocking density of 10 fish m-2. At the end of maintenance, a selection process is carried out on the weight traits. Parameters observed included growth, survival, and genetic values. The results showed that the growth and survival in the F-4 blue tilapia population, male and female selected populations, had a higher value than in the non-selected population. The realized heritability value of the population growth character of the F-4 blue fish is in the high category. The difference in the average weight of the selected blue tilapia and the control was equivalent to an increase in genetic value added by 15.06% (male population) and 17.92% (female population).

Highlight Research The genetic diversity of fish and shrimp from mangrove habitats was relatively substantial, with a heterozygosity of 0.926 and the exception of Langsa samples. AMOVA revealed that the diversity among individuals in the populations were higher compared to those within individuals. DNA barcode in mangroves is useful in developing mangrove conservation and restoration initiatives Abstract Fish and shrimp are among the species that are vulnerable to high level of disturbance in mangrove ecosystem. This study aimed to investigate the implementation of 16S rRNA gene for fish and shrimp barcoding in mangrove ecosystems in North Sumatra and Aceh, Indonesia. 50 samples fresh fish and shrimp were collected from five mangrove ecosystems in North Sumatra, namely Belawan, Lubuk Kertang, Percut Sei Tuan, and Pulau Sembilan and Langsa of Aceh for DNA extraction process. The research was divided into four activities: sample collection, DNA isolation, PCR amplification, and data analysis. DNA was extracted using kit extraction (kit Reliaprep gDNA Tissue Miniprep System) and with PCR amplification. Genetic parameters were analyzed using Gen Alex 6.51 software and the relationship between sites was examined using the MVSP 3.22. The genetic diversity of fish and shrimp from mangrove habitats was relatively substantial, according to the findings, with a heterozygosity of 0.926, with the exception of Langsa samples, which were only identified in subclass A1. Genetic relationship between sites revealed that all samples clustered into two branches and were randomly dispersed within each site. This work confirmed the 16S rRNA gene worked for fish and shrimp barcoding in mangrove ecosystems, North Sumatra and Aceh, Indonesia and our findings are expected to be useful in developing mangrove conservation and restoration initiatives.

Highlight Research The biodiversity, distribution and capture of eels on Sumbawa Island are traced through local community knowledge There are four types of eels in Sumbawa, namely marmorata, A. celebensis, A. interioris, A. bicolor Eels are found in rivers, dams, estuaries and rice fields Eel is not the main catch Eel fishing by the community is carried out because the hobby of fishing is not for livelihood In general, people do not know about eel conservation in Indonesia Abstract Eels are an important fishery resource in Indonesia, but information regarding distribution, fishing patterns and utilization has not been well documented in order for it to assist in the management of eel fisheries. One of the areas in Indonesia that uses eels is the Sumbawa Island community. The local community knowledge approach is an important for fisheries management, because it is an inherent component of fishery resources. This is preliminary study of eels in Sumbawa Island. This study aimed to examine the distribution, pattern of fishing, and utilization of eels from knowledge of local communities. Data were taken through in-depth interviews with 166 respondents. The study was conducted from November to December 2021. Interviews were conducted to obtain information and knowledge from local communities about eels (locations where they were eels found, fishing gear used, time, season and, utilization of eel, and community knowledge regarding its protection status). The results showed that the eels are found in dams, rivers, and estuaries. Most eels were caught from November to December in rainy season. Most people catch eels out of a hobby. Fishing rods and stuns are the two main fishing tools used to catch eels. There are three types of eel utilization, namely (1) consumed, (2) distributed to family and neighbors, and (3) marketed. Respondents (83.64%) did not know about the limited protection for several species of eels.

Highlight Research 1. There were 26 active compounds from water clover leaf extract that were identified using GC-MS 2. In silico approach was used to screen potential anticholesterolemic compounds from water clover leaf extract 3. Anticholesterolemic compounds from water clover leaf extract were interacted with HMG-CoA reductase receptors and compared to native ligand and medicine 4. There were 6 potential anticholesterolemic compounds identified from water clover leaf extract Abstract Water clover (Marsilea crenata C. Presl.) is a widely available plant in Indonesia and often utilized as a traditional food ingredient. This plant is also traditionally believed to contain compounds that can decrease blood cholesterol. This study aimed to determine the compounds in water clover which have the potential to decrease blood cholesterol through inhibition of the HMG-CoA enzyme using in silico approach. This research was done in several steps, i.e., extraction using ethyl acetate solvent, identification of chemical compounds using GC-MS, and screening of compounds with potential to be anticholesterolemic agent through in silico using PyRx 0.8 (AutoDockVina and Open Babel GUI version 2.4.1), Discovery Studio Visualizer 2021, and PyMOL™ 1.7.4.5 software. Results showed that ethyl acetate extract of water clover contained 26 compounds, 6 of which were potential to be anticholesterolemic agent, i.e., phytol, 1,2-benzenedicarboxylic acid, 2,4-di- tert-butylphenol, diethyl phthalate, 1,2,3,4-tetramethylbenzene, and dipentene. Binding affinity values of those six compounds were lower than the native ligand of the HMG-CoA reductase, although still higher compared to pravastatin. The binding affinity value of pravastatin was -7.13 kcal/mol and the binding affinity value of 3-methyl glutaric acid as a native ligand was -5.33 kcal/mol, meanwhile, the lowest binding affinity value of compounds in water clover was phytol (-6.37 kcal/mol) and the highest was dipentene (-5.40 kcal/mol). Through in silico study, there were six compounds from water clover leaf’s ethyl acetate extract that could inhibit the HMG-CoA reductase. Therefore, water clover leaf has the potential to become an anticholesterolemic functional food ingredient.
突出Research1。水三叶草提取物经GC-MS2鉴定出26种有效成分。采用硅法从水三叶草叶提取物中筛选潜在的抗胆固醇化合物。水三叶草提取物中的降胆固醇化合物与HMG-CoA还原酶受体相互作用，并与天然配体和药物进行了比较。摘要水三叶草(Marsilea crenata C. Presl.)是印度尼西亚一种广泛种植的植物，常被用作传统食品原料。传统上认为，这种植物还含有可以降低血液胆固醇的化合物。本研究旨在确定水三叶草中有可能通过抑制HMG-CoA酶降低血胆固醇的化合物。本研究分几个步骤完成，即使用乙酸乙酯溶剂提取，使用GC-MS鉴定化合物，并通过计算机使用PyRx 0.8 (AutoDockVina和Open Babel GUI版本2.4.1)，Discovery Studio Visualizer 2021和PyMOL™1.7.4.5软件筛选具有潜在抗胆固醇药物的化合物。结果表明，水三叶草乙酸乙酯提取物中含有26种化合物，其中叶绿醇、1,2-苯二甲酸、2,4-二叔丁基苯酚、邻苯二甲酸二乙酯、1,2,3,4-四甲基苯和二戊烯6种化合物具有潜在的降胆固醇作用。这六种化合物的结合亲和力值低于HMG-CoA还原酶的天然配体，但仍高于普伐他汀。普伐他汀的结合亲和值为-7.13 kcal/mol，作为天然配体的3-甲基戊二酸的结合亲和值为-5.33 kcal/mol，而水三叶草中化合物的结合亲和值最低为叶绿醇(-6.37 kcal/mol)，最高为二戊烯(-5.40 kcal/mol)。通过硅片实验，从水三叶草乙酸乙酯提取液中分离出6个能抑制HMG-CoA还原酶的化合物。因此，水三叶草叶有潜力成为一种抗胆固醇的功能性食品成分。

Highlight Research There are 26 species identified to be originated from the bay, which the highest diversity in Indonesia Six species found in Kwandang Bay is showing trends of decreasing populations and two species vulnerable based on IUCN conservation list Growth model and Fulton condition factor determined for 14 species indicates that they live in a good state of well beings in the bay The models and condition factors also reflect the adequate food resources required for grouper growth which makes Kwandang Bay as a good habitat for groupers Abstract Grouper fishery has been the source of income for 3,700 fishermen in Kwandang Bay. Since 2017, grouper populations in Kwandang have been depleting due to the absence of management. This research aimed to analyze species composition, length-weight relationship, and condition factor of the groupers. Samples were collected from fishers who caught the fish using traps, speargun, and handline. Samples were identified through a method by Heemstra and Randall, while the length-weight relationship was estimated using log-linear regression and t-test. The number of specimens identified during January - December 2021 was 1,571 individuals. Research showed that those samples consisted of 26 species under eight genera. Six species found in Kwandang Bay were showing trends of decreasing populations and two species were vulnerable based on the IUCN conservation list. Length-weight relationship analysis of 14 grouper species resulted in b value ranging from 1.6359 to 3.4417 and R2 ranges from 0.7718 to 0.9858. A significant test at a 95% confident interval showed that 14 species had an isometric growth pattern. Fulton condition factors show that Kwandang Bay is an essential habitat for groupers, and the bay can support the fish growth due to the adequate food availability.

Highlight Research Mangrove rehabilitation area has a better potential for carbon sequestration The more trees that grew and developed with a large DBH size the more affected the biomass, carbon content and carbon sequestration of mangroves. Among the four species studied, mucronatais characterized by highest carbon density storage Temperature and salinity affect the value of mangrove biomass, carbon content, and carbon sequestration Abstract Among its many advantages, mangroves have a function as carbon sequestration and storage. The aim of this study was to determine the differences in the ability of various rehabilitated mangrove species of carbon Sequestration of Above-Ground Biomass. This study was conducted from June 2020 to December 2021 in Kedung, Mlonggo, and Keling Subdistricts, Jepara Regency, Central Java, Indonesia. The mangrove plantation was a result of a rehabilitation programme sponsored by a society and the local government since 2009. Carbon sequestration measurement in tree biomass was estimated by a non-destructive method i.e., by measuring the Diameter at Breast Height (DBH). Statistical analysis to determine the relationship between carbon storage in several species of mangroves and the environmental factors were performed using XL stat 2022. There were 4 (four) mangrove species found i.e., Avicennia marina (Forssk) Vierh, Rhizophora apiculata (Blume), Rhizophora mucronata (Lamk), and Sonneratia alba Sm. The highest CO2 absorption (397.21 tons ha-1) was obtained both in Kedung and Mlonggo stations with R. mucronata, whereas in Keling station with R. apiculata the absorption was 54.27 tons ha-1. The results of Principal Component Analysis (PCA) showed that the number of trees and DBH had a relationship with biomass, carbon content, and carbon absorption. Diameter at Breast Height in mangrove species can be used as indicators to assess carbon sequestration in Above Ground Biomass.
红树林恢复区具有较好的固碳潜力，生长和发育的树木越多，胸径越大，对红树林生物量、碳含量和固碳的影响越大。温度和盐度影响红树林的生物量、碳含量和固碳价值。摘要红树林具有固碳和储存碳的功能。本研究的目的是确定不同恢复红树林物种对地上生物量碳固存能力的差异。本研究于2020年6月至2021年12月在印度尼西亚中爪哇省杰帕拉县Kedung、Mlonggo和Keling街道进行。红树林种植园是2009年以来由一个社会和当地政府赞助的恢复计划的结果。通过测量胸径(DBH)的非破坏性方法估算了树木生物量的固碳量。利用XL stat 2022对几种红树林碳储量与环境因子的关系进行了统计分析。共发现4种红树:Avicennia marina (Forssk) Vierh、Rhizophora apiculata (Blume)、Rhizophora mucronata (Lamk)和Sonneratia alba Sm。科东站和姆隆戈站的吸二氧化碳量最高，为397.21 t ha-1，而科岭站的吸二氧化碳量最高，为54.27 t ha-1。主成分分析(PCA)结果表明，林分和胸径与生物量、碳含量和碳吸收量之间存在显著的相关关系。红树林胸高直径可作为评价地上生物量碳固存的指标。

Highlight Research Sulfuric acid soil causes extreme acidity of the water (pH<3) and is unsuitable for fish culture Well management for sulfuric acid soil reduce the high risk of soil and water acidity The use of an appropriate combination of different liming is better than the single material to solve the very low pH Combination of dolomite and hydrated lime increased the pH and alkalinity Abstract The application of liming material should consider the amount and quality of chemicals related to cost expenditure and target of expected soil properties since it is usually done with an incorrect number’s estimation and expected soil-water quality which produces unsuccessful results. This study aimed to analyze the effect of different percentages from each combination of dolomite and hydrated lime (DH); DH1 (75:25), DH2 (50:50), and DH3 (25:75), which used five replications to the soil and water quality. The soil samples were taken from the earthen pond of semi-intensive tilapia fish (Oreochromis niloticus) culture in Lat Bua Luang, Rangsit, Thailand, placed into 50 plastic pots (volume = 1.5 L), and mixed with lime of different compositions. Based on the results, the mixture of dolomite and hydrated lime (DH) increased the soil and water pH into the desirable ranges (7.4-8.6). The alkalinity of DH treatments was not higher than that of the single dolomite (DA) or hydrated lime (HA). However, the value was still sufficient (>75 mg/L as CaCO3) to buffer water quality changes. Several depletions of the toxic materials (total aluminum, iron, and manganese) caused by sulfuric acid (FeS2) had been observed in combination treatment, especially in DH1. On the contrary, the essential base cations, calcium, and magnesium increased beyond the single treatment, either dolomite (DA) or hydrated lime (HA). A combination of dolomite and hydrated lime (DH1) as an alternative treatment to remedy aquaculture ponds in acid-containing soil is suggested in terms of efficiency and possible cost-effectiveness.

Highlight Research The elvers of Anguilla were identified through the morphological and molecular markers The result of morphological and molecular identification is different The molecular identification helps to confirm the morphological identification Based on this study molecular identification of the elvers of Anguilla found in river estuaries of Central Java is Anguilla bicolor bicolor Abstract An inventory of the presence and diversity of Anguilla spp. needs to be carried out as a basis for sustainable resource management. Conventional techniques based on morphological characteristics—are often less effective considering the morphological characteristics of Anguilla spp. are very identical and not so many can be observed, especially at the young eel stage. DNA-based molecular identification can be a way to determine diversity and phylogeny for conservation and inventory purposes. This research aimed to determine the diversity and phylogeny of Anguilla spp. obtained at the estuaries of Serayu River in Cilacap, Luk Ulo River in Kebumen, and Jali River in Purworejo in Central Java, Indonesia. A total of 10 samples were taken from each research location were analyzed morphologically, then it is known that there are 4 morphologically different samples at each research location so that a total of 12 samples were taken for molecular analysis. MEGA was used to construct the phylogenetic trees via Neighbour Joining (NJ) algorithms using the Kimura 2-parameter model with uniform rates and obtained by 1000 bootstraps replication. There are four species of Anguilla spp. identified morphologically, namely Anguilla bicolor bicolor, Anguilla bicolor pacifica, Anguilla obscura, and Anguilla australis. The species of Anguilla spp. that is molecularly identified is Anguilla bicolor bicolor with an identity percentage of > 98%. All samples are also known to be related to Anguilla bicolor bicolor identified in other countries.

Highlight Research Most businesses, including dried fish processing, are decided and conducted under conditions of uncertainty Each type of fish that is processed has different risks, both in terms of the source, level, and impact of the risk Fish processing SMEs in Bengkulu Province face moderate business risk on all sources of risk, except production risk Three important strategies to prevent high production risk, namely, the formation of joint business groups, the introduction of business risk insurance, and the downstream processing of processed dried fish products Abstract Every business always faces risks, including micro, small, and medium enterprises processing dried fish. Thus, it is crucial to examine the risk's sources, impacts, and response to risk. This research aimed to analyze the risk management process by identifying the risk sources, analyze the probabilities and risk effects, and design alternative strategies to prevent and control business risk that might be faced by MSMEs dried fish in Bengkulu Province. A total of 273 dried fish processing MSMEs were surveyed and interviewed. The data were analyzed using descriptive statistics and risk management approach. The main risk faced by dried fish producers was the production, included the raw material availability, input prices, and output prices. Each type of dried fish had different probability of risk occurrence where Kerong, Teri, and Gaguk had a high probability of risk occurrence despite their low impact on the scarcity of raw material availability. Moreover, Teri, Kepala Batu, and Bleberan had a high probability and impact risk in the input price. Considering the output price, only Kepala Batu is observed to have the probability and risk impact. Three strategies were designed to prevent and control risk, namely the establishment of joint business groups, introduction of business risk insurance, and downstream processing of dried fish products. SME fish processing does not encounter significant business risks. All risk sources are still regarded as moderate, with the exception of the production risk, which has a high-risk level.
