Abstract

Betta fish (Betta splendens) are ornamental fish with a long history of domestication and selective hybridization aimed at enhancing phenotypic variation. This study aimed to evaluate the effect of reciprocal hybridization between crowntail (CT) and doubletail (DT) strains on the phenotypic variation of the offspring. Four breeding combinations were applied: TA (CT♂ × CT♀), TB (DT ♂ × DT ♀), TC (CT♂ × DT♀), and TD (DT♂ × CT♀), representing intra- and inter-strain crosses between crowntail (CT) and doubletail (DT) broodstock. The experiment was conducted for 75 days, from spawning to juvenile rearing. Observed parameters included meristic and morphometric characteristics, coloration, growth performance, and survival rate of the offspring. The results indicated that reciprocal hybridization significantly affected the observed parameters. Male and female offspring from treatments TC (0.99681) and TD (0.99709) showed closer correlations with control TA (CT♂ × CT♀) in meristic characters. In terms of morphometric traits, male offspring from treatments TC (0.99054) and TD (0.98765) were more closely associated with treatment TA, whereas female offspring showed a stronger correlation with treatment TD. Hybridization between crowntail and doubletail white platinum strains produced novel color variations, including platinum-red and platinum-silver phenotypes. Furthermore, the growth performance of reciprocal hybrids differed significantly (p < 0.05) from that of the control groups. These findings demonstrate that reciprocal crossing between crowntail and doubletail strains influences phenotypic expression in offspring.

Abstract

The Penimbangan is one of the potential locations for underwater tourism in the Regency Buleleng, by unique dive spot. Planning and sustainable coastal development are essential for the continuity ecosystem, sea, and economy. Fish and coral studies in Penimbangan, District Buleleng, occurred from December 2022 to February 2023. Location observation shared four sites of data retrieval. The determination sites study uses purposive sampling based on the spread of coral naturally. Data was collected by Underwater Photo Transect (UPT) for coral and Underwater Visual Census (UVC) for fish. Transect area coral 50m long with quadratic transect (58cmx44cm), and classified categories using CPCe software. Transect area fish of 350 m2 (length 70 m, limit right and left 2.5 m), identified fish to level species. The most studied habitat associations in coral reefs are coral (HC) and fish in coral assemblages. Percentage composition substrate basis in Penimbangan, namely dead coral with algae (106.74), coral (90.27), and sand (70). Lifeform coral is found in as many as ten types; the most are CM (39.00), CE (23.20), and ACS (10.07). A total of 17 families with 70 reef fish species were recorded in this study. The family with the most species is Pomacentridae (25), followed by Chaetodontidae (9) and Labridae (8). The composition of fish will vary according to the type of habitat. Different coral habitats covered by benthic influence the abundance of certain trophic levels of reef fish in an area of water.

Abstract

Tuna is one of the most important fishery commodities for export. Commodities that can be exported must first have certificates of feasibility for class A and class B fish processing. Class A fish processing feasibility certificates are used for export at the international level while those in class B are used for exports at the Asian level. The initial certifications that need to be met are Good Manufacturing Practices (GMP) and Sanitation Standard Operation Procedure (SSOP). The aims of this study was to determine the profile of the Fish Processing Unit (UPI) with processing feasibility certification with A and B qualifications for tuna commodities through the application of Good Manufacturing Practices (GMP) and Sanitation Standard Operation Procedure (SSOP) and deviations that occur in Fish Processing Units (UPI). The method used in this study is a quantitative descriptive observational design. The results show that many of the results of supervision of feasibility certificates for processing medium-large scale fish processing units in East Java still have a B qualification. From the results that tuna is still widely exported at the Asian level.

Abstract

Tujuan kegiatan program kemitraan masyarakat ini adalah mengaplikasikan teknologi pembenihan ikan lele melalui induksi pemijahan ikan untuk pemberdayaan Pokdakan An Nur di Desa Kaduara Barat, Kecamatan Larangan, Kabupaten Pamekasan, Madura, Jawa Timur sebagai upaya produksi benih ikan lele secara mandiri. Metode kegiatan yang dilakukan adalah penyampaian materi dan diskusi, tutorial, pelatihan dan praktek secara langsung tentang teknologi induksi pemijahan (TIP), serta pendampingan mitra secara berkelanjutan. Penyampaian materi dan diskusi dilaksanakan untuk memberikan pengetahuan tentang teknologi dalam pembenihan ikan, khususnya mempercepat pemijahan ikan. Pelatihan dan praktek TIP dilaksanakan menggunakan indukan ikan lele yang siap untuk dipijahkan. Hasil kegiatan memberikan pengalaman bagi kelompok mitra bahwa TIP dapat mempercepat proses kematangan gonad dan pemijahan induk ikan lele, serta meningkatkan persentase penetasan telur hingga lebih kurang 90%.
