Krendet is one of the fishing gears used to catch Lobster in the South Coast of Java. Krendet is a passive fishing gear. Lobster is a fishery commodity that has high economic value. This research was conducted to determine the difference in lobster catches based on differences in fishing time and bait types on Krendet fishing gear. The method used in this research is experimental fishing with 4 treatment combinations and 6 repetitions. The difference in fishing time used was morning – afternoon and afternoon – morning, while the bait used was trash fish and no bait as a control. This research was carried out in February 2021 in the waters around the Sadeng area, Gunung Kidul. The analysis carried out in this study used the Two Way Anova Test method. The results showed that the time difference had an effect on the number of catches. The effective time to catch Lobster is at night. This can be caused by Lobster's behavior or habits which tend to be active at night. Giving bait to Krendet is also able to increase the number of catches. The trash fish bait is able to lure the Lobster to come closer to Krendet. Giving bait to Krendet is also able to increase the number of catches. The trash fish bait is able to lure the Lobster to come closer to Krendet so that the Lobster can be trapped.Keywords:KrendetLobsterCoastal Fishing PortSadeng

White shrimp (Litopenaeus vannamei) cultivation activities have developed rapidly in Indonesia. White shrimp aquaculture which is carried out intensively with high stocking densities has caused several problems, such as low survival and suboptimal growth. This study aimed to increase the growth, feed conversion, and survival of white shrimp through a combination of probiotics (Lactobacillus sp.) + turmeric flour (Curcuma longa) in feed. The method used in this study was Completely Randomized Design (CRD) with four treatment levels and three replications. The results revealed a significant effect (P0.05) on the value of the daily growth rate (DGR), absolute growth rate (AGR), specific growth rate (SGR), survival rate (SR), feed conversion ratio (FCR), and feed efficiency (FE), but no significant effect (P0.05) on the value of the absolute length rate (ALR). Giving probiotics 10 ml+5 g turmeric flour/kg feed (treatment B) was the best treatment for white shrimp aquaculture, including DGR, AGR, ALR, LPS, SR, FCR, and FE values. Furthermore, the results also revealed that increasing the concentration of turmeric flour in the feed, was negatively correlated to the growth and survival of white shrimp.

Most of the coastal areas of Aceh Besar are areas of accumulation of organic compounds, one of which is Organic Carbon (OC). The purpose of this study was to analyze the chemical content by looking vertically at the content of OC, soil pH and Calcium Carbonate (CaCO3) on the coast of Aceh Besar District. Analysis of the OC content using the Walkley and Black method, while to analyze the Calcium Carbonate (CaCO3) using the Titrimetric method. Especially for the analysis of soil pH, only use a pH meter. The results showed that each station had different levels of OC and carbonate. Generally, the presence of OC decreases with depth, while the carbonate content varies. Especially for soil pH, the pH is relative to the alkaline state for each depth. The range of OC content for all stations is 0.18 – 2.48%, Carbonate 5.36 – 13.27% and pH 6.37-8.73.Keywords:CoastalOrganic CarbonCarbonateSoil pH

Intensive shrimp ponds are characterized by the high stocking density of shrimp and artificial feeding and are equipped with an irrigation network system. The purpose of this study was to analyze the intensive L.vannamei pond with an irrigation system based on Vibrio spp. distribution to determine environmental quality degradation in terms of the treat of pathogenic bacteria. This study was carried out for one production cycle from March toJuly 2021 in an intensive shrimp farm in Sarjo Village, Pasangkayu Regency, West Sulawesi. The parameters analyzed in this study consisted of Total Bacterial Count (TBC), Total Vibrio Count (TVC), yellow and green colony Vibrio spp. in water using the spread plate method. Water samples for bacterial analysis were taken from 1) source water: (a) surface (0–50 cm depth) and (b) pump mouth; 2) treatment pond; 3) aquaculture pond; 4) Waste Water Treatment Ponds (WWTP); 5) outlet (before discharge into public waters). The results showed that the distribution of bacteria from seawater to WWTPs pond still increased the abundance of Vibrio spp., although the abundance of Vibrio spp. is still safe or below the maximum limit of 104 CFU/mL. Distribution of Vibrio bacteria in Intensive L.vannamei Pond Sarjo Village, West Sulawesi gave a relatively good pond performance because it was characterized by an abundance of Vibrio bacteria in the pond irrigation system from inlet to outlet which was still below the maximum limit and high pond productivity.Keywords:Intensive shrimp pondPathogenicVibrio spp.Pond performanceAquaculture

The research was conducted to determine the abundance, diversity, uniformity, and dominance of plankton in fish stomachs and waters that are expected to provide information about water productivity. The research was carried out in a tributary of the Ogan River, Indralaya District, Ogan Ilir Regency, South Sumatra at three stations, namely Indralaya Mulya Village, Tanjung Seteko Village and Muara Penimbung Village. The method used field surveys and location determination using purposive sampling with fish stomach contents, water samples for plankton observations, and water quality parameters. Fish sampling was carried out six times in 3 months, and water samples for plankton observations were one time per month, from April to June 2018. Plankton is found in fish stomachs and waters with a total abundance of 35.6 - 448.12 ind/l plankton consisting of 8 divisions with 11 classes. The plankton diversity index has moderate diversity and moderate community stability with a value between 1.11 - 1.45. The uniformity index of plankton in the fish stomach showed small uniformity of plankton (0.41-0.67), while in the waters, at station three and station 1 in April, the uniformity was high (E values 0.72 and E 0.93). The value of the plankton dominance index is in the range of 0.27-0.37. No species dominate other species or D = 0 (0.5), with moderately polluted water quality

Probiotics are beneficial microbes in living things that are useful for improving the balance of microbes in the digestive tract and have a positive influence on the physiology and healthiness of the host. This study aimed to obtain bacterial isolates that could be used as probiotics from striped mullet (Mugil cephalus) and to characterize it macroscopically, microscopically, and biochemically. Isolation of probiotic bacteria was carried out using the spread plate method. The medium used to isolate probiotic bacteria was MRSA (De Man Rogose Sharpe Agar) medium. The probiotic test was carried out by hydrolysis of starch and casein. The diversity of bacterial morphology was observed based on macroscopic, microscopic, and biochemical tests. A total of 2 probiotic bacteria (PIB 1 and PIB 2) were obtained. The characterization results showed that the two probiotic bacteria belonged to the Gram-positive bacteria, in the form of bacilli which had different colony morphology. The results of morphological and biochemical tests indicated that one bacterial isolate belonged to the genus Bacillus (PIB 1) and the other isolate belonged to the genus Lactobacillus (PIB 2).

Data on bycatch in the fishing effort required to manage fisheries resources. Unfortunately, the data on small-scale and traditional fisheries is still lacking. It makes it challenging to make fishing policies and regulations. Survey activities and experimental fishing were conducted to determine and analyze the composition of the main catch, bycatch and discarded by the local fisher's bottom traps in Sibolga, North Sumatra, Indonesia. Five units of the trap with a size of 150 cm x 100 cm x 50 cm (length x width x height) were used to collect fish data. These five trap units operated in the fishing ground, where local fishers usually operate their fishing gear. The fishing operation carried out within 1 mile of the coastline with water depths ranging from 7-10 meters. The duration of trap setting around 5-7 days for each fishing operation. A motorboat operated with a weight of 5.8 GT. The results showed that the total bottom trap catch consisted of 329 individuals with a total weight of 151.4 kg and 12 demersal fish species. The main catch was 148 individuals (88.9 kg), or 44.7% of the total catch during the experiment i.e. Chepalapholis urodeta, Ephinephelus areolatus, Epinephelus chlorostigma, Plectropomus leopardus, Ephinepelus coioides, Lates calcarifer, Lutjanus malabaricus, and Lutjanus erytropterus. The bycatch was 151 individuals (57.1 kg) or 46.1% i.e. Lethrinus obsoletus, Lutjanus ehrenbergii, Acanthurus auranticavus, Platax teira, Nemipterus japonicus, Scarus rivulatus, Lutjanus johnii, Siganus canaliculatus, Caesio cuning, and Taeniura lymma.While the discarded catch amounted to 30 individuals (5.4 kg) or 9.2% i.e. Naso brevirostris, Diodon holocanthus, and Diadema setosum. The bycatch utilization obtained by fishers was 83.4%, and the unutilized was 16.6%. The percentage of fish sizes worthy for consumption was 135 individuals (74.6%), and the size unworthy for consumption was 46 individuals (25.4%).Keywords:Fishing groundFishing gear Fishing operation Main catchTrap

Sharks is the dominant bycatch of purse seine and bottom longline vessels that landed in Kutaraja ocean fishing port, particularly pelagic thresher shark species (Alopias pelagicus). The management of shark fisheries in Aceh water is not well implemented. According to the IUCN red list, the pelagic thresher shark has been classified as an endangered species. The capture and trade of pelagic thresher sharks are regulated by CITES (Appendix II). So that Indonesia has to comply with the procedures of CITES due to it has been adopted through the Decree of Minister of Marine Affairs and Fisheries of the Republic of Indonesia Number 61/PERMEN-KP/2018. However, the exploitation and trading of the A. pelagicus continues and is not properly managed. It will threaten the extinction of the pelagic thresher shark population and in terms of a negative image of fisheries management in Indonesia, in particular. Thus, integrated management such as the ecosystem approach to fisheries management (EAFM) is needed to solve this problem. This study aims to evaluate the fisheries management status of the pelagic thresher shark based on EAFM indicator of fish resources domain, focusing in the Kutaraja ocean fishing port. This research was conducted by field measurement and interviews with key stakeholders. Data were analyzed using a multi-criteria analysis (MCA) approach through development of a composite index. The results showed that the trend of CPUE tends to fluctuate in the last 5 years. The total length of the sharks was relatively constant. The proportion of juvenile pelagic thresher sharks was 16% male, and 28% (female), and the shark was bycatch (1%) of the purse seine fishery, the fishing ground was getting further away and seemed to go close to the shark habitat. Based on this assessment, one could conclude that shark's fishery resources were in 'good' category, however, some indicators need to improve through better fisheries management actions.

White snapper Lates calcarifer is one of the marine fish commodities that has important economic value. The addition of immunostimulant ingredients in feed is believed to increase immunity and increase fish growth. This study aims to determine the effect of adding β-glucan to feed on white snapper (Lates calcarifer). This study used a completely randomized design (CRD) consisting of 5 treatments with 3 repetitions. White snapper used with a weight of ± 6 grams and a length of ± 7. The frequency of feeding is done 3 times a day. The results of the ANOVA test showed that the addition of β-glucan in the feed significantly affected the growth rate of the fry of white snapper (Lates calcarifer) (P0.05). The best treatment in this study was treatment E (commercial feed + β-glucan 8g/kg feed) which gave the best growth in White snapper where this treatment was able to increase absolute weight (4.51 ± 0.29), absolute length (4 .84 ± 0.284), specific growth rate (2.09 ± 0.15), FCR (1.00 ± 1.00), feed utilization efficiency (97.42 ± 0.50) and survival (100.00 ± 0.00).
