Mince fish can be made into a gel-based product. One of the gel-based products is fish ball. Making fish balls can use economical fish to add value to a product. This study aims to determine the differences in the physical characteristics of fish balls with the use of different types of fishThe treatment in this study is to use different types of fish. The types of fish used were Tilapia (Oreochromis mossambicus) and Mackerel (Restrelliger sp) Other additional ingredients are tapioca flour and seasoning fo making fish ball. The calculating in this study is the yield of fish fillets (skinless) and physical characteristics of product. The results of this study showed that the yield value of tilapia fish fillet is 33, 76% with the number of meatballs produced is 9-13 meatballs. While the yield of mackerel fillet was 49.29% with the number of meatballs produced as many as 24-29 meatballs. The characteristic value of the appearance of the tilapia fish ball is 8 while the mackerel meatball is 7.6. The aroma value of tilapia and mackerel fish balls were 7.4 respectively. Texture value in tilapia fish meatballs is higher than mackerel meatballs, which is 8.2.

The purpose of this research was to determine the most selective mesh size of gillnet fishing gear for Pampus argenteus in coastal waters of Pangandaran Regency, West Java. Research on the selectivity of gillnet fishing gear was carried out in the coastal waters of Pangandaran, West Java Province, from August 2018 to January 2019. The method used in this research is experimental fishing, namely operating gillnet fishing gear directly in the fishing area with fishermen. The primary data collected was the measurement of the catch (fish weight, number, fork length, how the fish was caught, circumference (girth opercullum, maximum body girth). Meanwhile, the secondary data collected were supporting data from the Pangandaran District Fisheries and Marine Service, and literature study. In determining the sampling, the method used is the purposive sampling method. The operation of gillnets using 4.5 inches obtained a higher proportion of main catch (75%) than gillnets with a mesh size of 5 inches (44%). Gillnet with a mesh size of 4.5 inches, the silver pomfret caught was distributed between 17-22 cm in size with the highest mode in the 19 cm fork length. Unlike the gillnet fishing gear with a mesh size of 5 inches, the silver pomfret caught was distributed in the fork length range of 17-25 cm with the highest mode in the length class 19 cm fork length. mesh size 4.5 inches has a hanging ratio value of 0.51. Meanwhile, the 5 inch mesh size has a hanging ratio value of 0.54. Based on the length distribution, gillnets with a mesh size of 5 inches were more dominant in catching silver pomfret in a larger size class interval than gillnets with a mesh size of 4,5 inches. Based on the L50 value, both selective gillnets caught more fish at 50% second chance. The selectivity curve shows that gillnet fishing gear with a mesh size of 5 inches has more selective results than gillnets with a mesh size of 4.5 inches.

This study was conducted to investigate the stomach contents of two commercially important fish species (Tilapia zilli and Oreochromis nilocticus)  from Wanzun River, Northcentral Nigeria using frequency of occurrence and volumetric methods between January to April 2019. Fish samples were collected monthly with help of Fishermen using various fishing nets and traps. One hundred (100) individual fish of each species were collected and their stomach contents were examined. The results obtained expressed in mean percentage indicated that out of the one hundred (100) individual fish of each species examined,Twelve (12%) fish had an empty stomach contents in Tilapia zilli, and out of the 100 samples examined, Seventeen (17%) fish had an empty stomach content in Oreochromis nilocticus. The stomach contents of both Tilapia zilli and Oreochromis nilocticus consist of detritus, insects, fish remains. Algae/protozoans plant materials and molluscs. Both fish species are omnivorous feeders and occupy the same ecological niche.The study reveals the importance of algae, fish, insects and plant materials as food for fishes and they form important part in the diet of the species examined.

This study was conducted from August 2020 to July 2021. Competitiveness can be interpreted as the ability of a region to make it excel in producing a commodity more than any other region. The competitiveness, especially in the field of brackish water aquaculture can be known through several indicators, i.e. human resources, infrastructure, production and science and technology. This study aims as an effort to realizing fisheries development in Indonesia by knowing the competitiveness profile of brackish water aquaculture in Indonesia through qualitative descriptive analysis method. The research procedure was conducted in several stages, the first of which was the collection of secondary data at the Ministry of Marine Affairs and Fisheries. The second stage is to analyze the primary data in the form of expert opinions or competent people in their fields. Then the last stage is to analyze the data that has been obtained during the research. Based on the results of the study, it was concluded that the competitiveness profile of brackish water aquaculture in Indonesia was outperformed by south Sulawesi province with a final value of 17.03, while the region with the lowest competitiveness value was Riau Islands Province with a final value of 0.05.

Pangandaran has a great fishery potential. Therefore, fishing communities make fisheries a source of economy, especially in the fishing sector, namely by buying and selling the catch. Fish buying and selling activities are increasing in line with the fish consumption needs of the community. This has an effect on increasing fishing activity, causing a decrease in fish production. The study was conducted to find out information on the IUCN group of fish that are still sold in the fish market. The research was conducted by direct observation in the field at the Pangandaran fish market and its surroundings. Observations show that the Pangandaran fish market still sells fish that are listed in the IUCN. There are sharks and ray fish sold at the Pangandaran fish market. The species found were 3 species spread over five observation locations with details of one species listed IUCN-Least concern, and one species registered IUCN-Vulnerable for hammerhead shark and IUCN- Near Threatened for blacktip shark. The sharks identified as Appendix II species while the freshwater stingray belongs to Appendix III of CITES. Because endangered fish are still sold routinely, conservation is needed to preserve the biota. Fisheries management in the catching process also needs to be done so that endangered fish caught can be minimized.
