Abstract

Artemia salina is a natural food source known for its high nutritional quality. It is commonly used in larval rearing due to its ability to produce long-lasting cysts that can hatch at any time. These characteristics make A. salina very suitable for sustainable cultivation. In this study, the feed consisted of rice bran suspension enriched with Isolated Soy Protein (ISP) meal. The aim was to investigate the effect of different protein concentrations in the rice bran suspension feed on cyst production in A. salina broodstock. This study used a Completely Randomized Design (CRD) with five treatments and four replications. The treatments included P0 (without ISP meal, 25% protein concentration), P1 (ISP meal, 40% protein concentration), P2 (ISP meal, 45% protein concentration), P3 (ISP meal, 50% protein concentration), and P4 (ISP meal, 55% protein concentration). Data analysis was performed using ANOVA followed by Duncan's multiple range test. The results showed that variations in protein concentration with the addition of ISP flour had a significant effect (P < 0.05) on total cyst production and cyst production per broodstock of A. salina. The highest total cyst production (710.67 cysts/L) was achieved in P4 with a protein concentration of 55%, while the highest cyst production per broodstock (28.67 cysts/broodstock) occurred in P2 with a protein concentration of 45%.

Abstract

Macrognathus aculeatus is a local fish from the Bengawan Solo and Brantas Rivers threatened with extinction. Due to the lack of literacy on the biology of this fish. Biological parameters can be used to determine the condition of this fish in nature. Field observations at five stations from the two rivers were conducted to obtain samples. Biological and reproductive parameters such as weight and length, gonad maturity level (GML), Gonadosomatic Index (GSI), Hepatosomatic Index (HSI), and Condition Factor (CF) were the parameters observed in this study. All data obtained were presented as mean and standard deviation. Furthermore, analysis of variance was conducted using ANOVA (p < 0.05) to determine differences in samples from each observation station. The results showed that some biological factors had significant results (p < 0.05) on Gonadosomatic Index and Hepatosomatic Index). However, there was no significant difference (p > 0.05) in the condition factor. On the other hand, there were significant differences (p < 0.05) in body weight, total length, ovary weight, and fecundity parameters across all sampling sites.

Abstract

Whiteleg shrimp (Litopenaeus vannamei) is one of the main fishery commodities since it has a high economic value. Vaname shrimp cultivated is done intensively where the stocking density and the amount of feed required are high. High stocking densities can trigger stress, increase possibility of physical contact among shrimps, and the spread of disease in shrimp becomes faster. The most common shrimp disease is Vibriosis where whiteleg shrimp are infected by Vibrio sp.. Whiteleg shrimp has an innate immunity system thus hemolymph has an important role in shrimp body defense. In this study, the research method used was purposive random sampling and was conducted from August to September 2023 by 50 shrimps sample. Assay of phagocytosis index (IF) which is a cellular response of the vaname shrimp body defense system was conducted at the Center for Brackish Water Aquaculture (BBPBAP) Jepara by applying a bacterial suspension of Staphylococcus sp. which has been attenuated and bacterial staining. Calculation of Total Vibrio Count (TVC) was conducted at the Laboratory of Bacteriology and Mycology, Faculty of Veterinary Medicine, Universitas Airlangga, by using TCBS (Thiosulfate Citrate Bile Salt Sucrose Agar) agar media from Vibrio sp. bacteria cultured from the hepatopancreas of shrimp samples. The results showed that vaname shrimp cultured in intensive ponds were infected with Vibrio sp. with a TVC value of 3.3x105 cfu/ml and an IF value of 0.87.

Abstract

Coral ornamental fish become potential fishery commodities, providing opportunities and challenges in managing fishery resources in Indonesia. This activity has long been done and has become one cause of damage to coral reefs in Indonesia. Changes in paradigm and technology currently applied in Indonesia are expected to provide a gradual regulatory and coral reef ecosystem improvement. The commercial trade of ornamental fish requires attention and rigorous regulation. The marine ornamental fish trade activity is expected to improve and drive the coastal communities' economy. The significant increase in exploitation is expected to be controlled with the right regulations. This regulation must refer to the concept of sustainable development established through the Sustainable Development Goals (SDGs), especially SDGs number 14 concerning life underwater. The existence of reef fish is enough to provide economic movement, which continues to heat up, especially after the pandemic and the reopening of flights and export activities abroad. However, multi-stakeholders should ratify the concept of sustainability and environment-friendliness. Support from the government, academia, industry, and community groups must be aligned and in tune to achieve sustainable development goals. Providing accurate information related to the biological characteristics of reef fish is an essential contribution for researchers that can be used directly by the community. Thus, the exploitation of reef fish can align with efforts to conserve coral reef ecosystems closely related to global warming and climate change.

Abstract

This study aimed to assess the impact of the Nile Tilapia (Oreochromis niloticus) cage fish farming on the water quality in two selected bays of the Bukavu basin, Lake Kivu. Physicochemical parameters (pH, temperature, electrical conductivity, total dissolved solids, salinity, dissolved oxygen, transparency) were measured in situ using a COMBO HI 98129 multi-parameter probe, PCE-PHD1 probe, and a Black and White Secchi disk. Water samples at different depths were collected using a Van-Dorn Sampler and phosphate, ammonia, nitrite, silicate, and chlorophyll-a were analyzed using a UV-VIS spectrophotometer. The results revealed that the pH, temperature, total dissolved solids, salinity, and transparency were significantly different (p ≤ 0.05) between the bays with cages and at the control bay, which may be due to the low movement of water, and the density of fish inside the cages. The water nutrients such as phosphate, ammonia, nitrite, silicate, and primary productivity were significantly different (p ≤ 0.05) within the bays with cages than at the control bay without cages. Overall, the results demonstrate that Tilapia cage culture contributes to the deterioration of water quality parameters accelerating the eutrophication process in Bukavu basin, Lake Kivu. Therefore, the study recommends relocating the cages to the bays not impacted by the anthropogenic activities from the catchment and regulating fish feeding according to the bioavailability of nutrients in the bays.
