type: item
description: One of the biggest fisheries products in NTB is tuna. Mataram City is one of the largest tuna production locations in NTB. This research aims to determine the sustainability status of tuna fish and the biological condition of its fisheries in the waters of the Lombok Strait and to determine the condition of the tuna fish population in the waters of the Lombok Strait. The method used in this research is a descriptive dependent survey method. In this research, data was collected through data collection techniques by sampling. Fish samples were obtained from the waters of the Lombok Strait which were landed by fishermen in Bintaro Village, Mataram Selatan, and Tanjung Karang, Mataram City, West Nusa Tenggara Province. Data on the length and weight of the fish were then analyzed for the level of sustainability using the parameters of age group, suitability for consumption, suitability for maturity, and suitability for catching. Biologically, the Lisong tuna fishery in the Lombok Strait can be categorized as a sustainable fishing activity because most of the fish caught are adults. The population of tuna caught by fishermen is not threatened because most of them have mature gonads.

Pengaruh Perbedaan Jenis Umpan Pancing Ulur (Handline) Terhadap Hasiltangkapan Di Kelurahan Bintaro Kecamatan Ampenan Kota Mataram
type: item
description: Fishing rods in Bintaro village are often also referred to as night fishing rods. The number of fishing rod units continues to increase every year. This increase occurs because the operation of the fishing rod (night fishing rod) has several advantages, one of which is that the cost of fishing operations is relatively small. The purpose of this study is to determine the effect of different types of handline fishing baits on catches, the most effective baits and get the most catches, and the feasibility of fishing rods in Bintaro kecamatan Ampenan kota Mataram. The study was designed using a Complete Randomized Design (RAL) with 3 treatments and 7 repeats, namely P1 (squid bait), P2 (lemuru fish bait), P3 (feather bait or artificial bait). The feasibility of fishing rods was analyzed using the B/C Ratio. The squid bait is used in the live state, while the lemuru fish bait is in a dead state. The results of the study the best treatment for effective catches and getting the most catches, namely using squid bait, got a total of 37 catches with 4 different types of fish. The results of the B/C ratio (3,403) show that the handline fishing business generates a profit so that it is feasible to run

Pengaruh Dosis Pakan Jentik Nyamuk (Culex sp.) Terhadap Pertumbuhan Benih Ikan Black Molly (Poecilia sp.)
type: item
description: This study aims to determine the effect of feeding different doses of mosquito larvae on the growth of Black Molly fish (Poecilia sp.). This study used a completely randomized design (CRD) experimental method with four treatments, namely P1 (6%), P2 (8%), P3 (10% natural feed dose for mosquito larvae), and P4 (Control, using Pellets). Each treatment was repeated three times. The container used is an aquarium measuring 40 cm long, 30 cm wide, and 30 cm high with a water level of 30 cm. The stocking density of Black Molly fish seeds in each treatment was 10 individuals. The observed data was analyzed for its diversity using Analysis of Variance (ANOVA). The results obtained indicate that feeding mosquito larvae has a significant effect on growth. Further tests using the Least Significant Difference (LSD) indicated that the 10% dose showed the highest weight growth with an average growth of 0.0071 g/day. Meanwhile, the survival rate of Black Molly fish fry in all treatments was still in the good category (more than 50%).
