Humpback grouper (Cromileptes altivelis) is one of the leading commodity food fish seawater is prospective to be developed because it has a high protein content is about 30-35% and the cholesterol content is quite low, around 3%. Hatchery of Cromileptes altivelis held in the Hall of Brackish Water Aquaculture (BBAP) Situbondo Regency East Java Province. Activities undertaken is the selection and preparation of the parent, pond preparation, water quality measurements, spawning, hatching eggs, larva, feeding, harvesting of pest eradication. The feeding is done adlibitum. During the course, identification of problems existing in Humpback grouper hatchery did not find any problems, just may need to be re-examined on elevating hatchability while still larvae.

This community service was conducted to asssist catfish farmers to solve their problem in producing catfish fry. Several problems identified in the initial survey were low quality of catfish fry as some broodstock were too old, high cost of feed, lack of capital and lack of production and financial management. Some activities undertaken in this community service were: introduction of broodstock, concrete ponds, workshop on induced spawning and probiotic production, training of production and financial management, demo-pond and monitoring and evaluation. The results of demo-ponds showed that introduction of broodstock, concreate ponds, induced spawning method, application of probiotics increased the catfish fry production up to 59,1 % which then improved the farmers income up to 49,4%.

Catch biomass and time-trend perception of Beach seine fishery were studied during 2015, from four different sites in East Java: Padikde Madura, Santan Island Banyuwangi, Prigi Beach Trenggalek, and Dangkal Beach Pacitan. The study aimed to assess the impact of recently Ministerial Decree (No. 2/2015) on this particular fishery. Catch biomass was analyzed based on swept area method. Time trend perception was traced back from fishermen in relation to reduced catch biomass, catch size, habitat degradation, and income contribution from the fishery. The results showed that Beach Seines in East Java are considerably subsistence. It swept fixed-bottom habitats of 1–9 ha. Average catch biomass for all sites was 15±19.4 kg trip-1. With low price of fish catch, fishermen cannot place down their family income solely from this livelihood. Beach seine is more as to maintain tradition of subsistence. Fishermen clearly observed the reduced in catch biomass and catch size compared to what it used to be (±30 years ago). With very low contribution to total catch in the region, negligible impact to habitat degradation, and consumed no fuel subsidy, it is no real reason to include this gear in general ban through Ministerial Decree of Marine Affairs and Fisheries.

Lempuk fish (Gobiopterus sp.) is one of the local species in Ranu Grati. The high level of Lempuk fishing and the low level of awareness of Grati community on the importance of conservation and domestication efforts, as well as the taxonomy of the fish itself have threatened the population. Therefore, long-term efforts should be undertaken to preserve and identify the origin of Lempuk fish by conducting a molecular phylogenetic study based on COI. This study aimed to determine, analyze and describe the kinship and phylogenetic relationships of Lempuk fish (Gobiopterus sp.). This study used a descriptive method, starting from the specimen collection, extraction by the Phenol-Chloroform method and amplification by the PCR method, to the screening process. The data analysis method used the MEGA 5 application. Phylogenetic study used the Maximum Likelihood method with a bootstrap value of 1.000 times. The results showed that the intra-population genetic distance of Lempuk fish is low at 0.00%. Genetic distance between the population of Lempuk fish is relatively high with G. brachypterus from Malaysia of 22.4%, Central Java of 21.5%, and India of 21.4% and with G. lacustris from Malaysia of 22.5%, the Philippines of 21.6% %, Thailand of 19.7%, and with G. chuno and G. semivestitus of 21.2% and 23.6% accordingly. The phylogenetic study obtained showed the formation of a separate group that is different between Lempuk fish group and other Gobiopterus fish, supported by a bootsrap value of 99%.

The spiny eels (family Mastacembelidae) is a fish that naturally and widely distributed on Java Island, especially in the Brantas River of East Java. This fish has high economic value, as a source of protein for local people and has recently popular as an ornamental fish among hobbyists. To fulfill market needs, fishermen must catch the fish from nature, leading to a severe population decline. Basic scientific information regarding species identification and determining the phylogenetic position fish species including the spiny eels is very important in order to support aquaculture, domestication and maintain its sustainability in nature. Specimens of the spiny eels were collected from Brantas River basin, East Java, at two localities in Malang and Kediri. Mitochondrial DNA from the cytochrome c oxidase subunit I was then sequenced on several randomly selected specimens. Results of morphological and genetic analysis using BLASTn showed that the specimens under study could be confirmed as Macrognathus aculeatus. Phylogenetic analysis using the Bayesian Inference method showed that M. aculeatus in this study has the closest relative to M. arai from Bangladesh. The phylogenetic reconstruction showed that individuals of M. aculeatus from Malang and Kediri were clustered together with individuals from Mojokerto with very shallow molecular divergence, indicating that they possibly originated from the same population. The results of this study can be used as basic information to design effective management of domestication, aquaculture, and conservation in the future.
