Abstract

Indonesia is one of the largest exporters of fresh and marine ornamental fish. However, several obstacles are faced by betta fish farmers, namely, such as poor colour quality, and low growth. There are various ways to improve colour quality, namely by adding pigment through feed. One of them is by utilizing purslane (Portulaca oleracea). This study aimed to analyse the effect of purslane plant extract (Portulaca oleracea) in increasing the brightness of the colour of betta fish (Betta sp.). The research method used in this study was a completely randomized design (CRD) method with 4 treatments 3 three replications. The treatments to be carried out were: P0 (100 g pellets), P1 (25 ml/100 g pellets), P2 (50 ml/100 g pellets) and P3 (75 ml/100 g pellets). Parameters observed: colour intensity, Absolute Length Growth, Absolute Weight Growth, and Survival rate (SR). The results of the study were that purslane extract from commercial pellet feed had a significant effect on the colour intensity of betta fish with a P3 dose of 75 ml/100 g pellet. In absolute length growth, the addition of purslane extract to commercial feed had a significant effect (p<0.05). For absolute weight growth and survival rate, no significant effect on betta fish.Keywords: Commercial Pellets; Purslane Extract; Siamese Fighting Fish

Abstract

Green catfish (H. nemurus) is a type of freshwater fish that has the potential to be cultivated. Green catfish cultivation needs to be supported by ideal environmental conditions so as to produce maximum survival rate and growth. One environmental technique that can be used is water level, because the higher the water column the more energy it will uses to move and can affect the growth of green catfish fry. This research aimed to determine the best water level for survival rate and growth of green catfish fry. This research was carried out in January-February 2024 at the Fisheries Basic Laboratory, Aquaculture Study Program, Fisheries Departement, Agriculture Faculty, Universitas Sriwijaya. This research used a completely randomized design (CRD) consisting of 4 treatments and 3 replication, namely P1 with a water level of 6 cm, P2 with a water level of 12 cm, P3 with a water level of 18 cm and P4 with a water level of 24 cm. This research was carried out for 30 days. The research results showed that differences in water level a significant effect on survival rate, growth, feed efficiency and oxygen consumption level but have no significant effect on blood glucose level. The results showed that the best treatment namely P3 resulted in absolute weight growth of 3.62 g, absolute length growth of 3.60 cm, feed efficiency of 80.00%, survival of 96.30%, blood glucose level of 15,00 mg dL-1 and oxygen consumption level of 1.12 mg O2 g-1 hours-1. The  water quality values for all treatments still support the survival rate of green catfish fry.Keywords: Green Catfish; Fish Growth; Survival Rate; Water Level

Abstract

Microplastics in the digestive tracts of fish can make their way into the food chain, reaching higher trophic levels, including humans, and potentially causing health issues. The Banjaran River in Banyumas Regency is one such waterway at risk of microplastic pollution. This study aimed to identify the types and abundance of microplastics in fish from the Banjaran River. Sampling was conducted at four strategically chosen stations based on land use, with three repetitions at two-week intervals. Analysis of the type composition and abundance of microplastics in the fish digestive tract using laboratory testing with microscope observations. Four types of microplastics were found in all samples with a predominance of fiber (37%), fragments (31%), pellets (19%), and film (14%). The abundance of microplastics in the fish digestive tract ranges from 12.8-20.5 particles/individual. The highest abundance of microplastics was found in broomstick fish, while the lowest abundance of microplastics was found in broomstick fish.Keywords: Banjaran River; Fish Digestion; Microplastics

Abstract

Mangrove crab (Scylla serrata), is one of the fishery commodities that has high economic value. This is because it tastes good and has high protein, around 52%. Mangrove crab cultivation is a cultivation technology that requires a relatively short time, which is around 15-30 days of maintenance with a low mortality rate of around (10 - 20). Diseases in mangrove crabs can be caused by fungi and bacteria. One of the obstacles in mangrove crab fattening activities is the occurrence of death during the maintenance process caused by bacterial disease attacks, so efforts are needed to prevent disease. Therefore, research is needed to determine the Identification and Prevalence of Pathogenic Bacteria (Vibrio sp.) In Mangrove Crabs in the City. This research was conducted in November 2023. Sampling was carried out when the crabs were molting based on the results of the study of mangrove crabs in Meuraxsa District, namely Vibrio sp. bacteria. The highest prevalence value of vibrio sp bacteria is isolate code A and C in Muraxsa District, Banda Aceh City, at 40% with the normal/moderate infection category. Water quality parameters at the cultivation location are still within the optimal range for cultivation.Keywords: Bacteria; Mangrove crabs; Identification; pathogenic; Prevalence

Abstract

Gourami (Osphronemus gouramy L, 1801) is one of the freshwater fish commodities with high economic value that has slow growth. The feed used is still very minimal so the growth rate of gourami fish is slow. One approach that can be taken to increase the growth and nutritional value of gourami fish is by adding nutrients in the form of omega-3 salmon fish oil to the feed. This study aimed to evaluate the enrichment of commercial feed with omega-3 in increasing the growth and nutritional value of gourami fish carcasses. This study was carried out from May to July 2023 at the Laboratory of Marine Microbiology, Faculty of Fisheries and Marine, University of Riau. This study used a completely randomized design (CRD) experimental method with 4 experiments and 3 replications, the experiments used were, P0 (without fish oil), P1 (salmon oil 5g/kg), P2 (salmon oil 10g/kg), P3 (salmon oil 15 g/kg). The fingerlings were raised for 60 days with a stocking density of 20 fish/container. The results showed that enrichment of feed with salmon fish oil significantly effect (P<0.05) on growth rate and increased nutritional value. Experiment P3 (salmon oil 15g/kg) produced a higher growth rate compared to other treatments, namely absolute weight of 9.05+0,76 g, absolute length of 4.80 cm, specific growth rate of 1.16+0,07 %, feed conversion ratio of 2.4+0,24%, efficiency feed of 40.5+4,0%, hepatosomatic index of 3.3+0,11%, viscera somatic index of 3.6+0,22%, mesenteric fat index of 3.2+0,06%, EPA of 2.85%, and DHA of 2.31%. In conclusion, adding salmon fish oil increases the growth and value of EPA and DHA in gourami fish meat. Water quality parameters were considered good with a temperature of 28-32oC, pH of 5.2-6.7, DO of 6.5-8.5 mg/l, and NH3 of 0.14-0.85 mg/l.Keywords: Feed Enrichment; Gourami Fingerlings; Growth; Nutritional Value

Abstract

Tuna (Thunnus sp) is a fish with high economic value, both in the export community and local consumption (Fernandez, 2021). The amount of tuna (Thunnus sp) production increases every year. The increasing amount of fishery production and the development of the fishery product industry have caused a lot of fishery waste to be disposed of without processing. Waste from fishery product processing reaches 20-60% of the raw materials. Waste from fishery products processed with tuna as the raw material consists of 17% head, 20% skin, 5% offal, 4% bones, and 2% fins. In general, tuna skin is thrown away without further processing. However, tuna skin is a good source of collagen and does not cause bovine spongiform encephalopathy (BSE). Collagen, which provides 30% of the total protein content, is the most abundant fibrous protein in animals. Collagen plays an important role in regulating the wound-healing phase. This study used the Cobalt-60 gamma irradiation method with a dose of 10 kGy. The results of this study are with bacterial tests, tuna fish powder that has undergone gamma irradiation with a bacterial contaminant value of 0.19 x 103, and mold testing with a value of 0.00 x 103 with a pH of both 6.78. Functional groups of tuna fish skin collagen include Amide A found in the absorption region of 3330 cm-1, Amide B found in the absorption region of 2924 cm-1, Amide I found in the absorption region of 1640 cm-1, Amide II found in the absorption region of 1406 cm-1, and Amide III found in the absorption region of 1242 cm-1.Keywords: Collagen; Gamma Irradiation; Tuna Fish Skin; Waste
