Abstract

Feed is an essential element that supports cultured fish's growth and survival. The purpose of the study was to determine the effect of differences in natural and artificial feeding on the growth and survival of dumbo catfish fry (Clarias gariepinus). The research was conducted from July to August 2022 with an experimental period of 40 days. The study used a completely randomized design with three treatments (artificial feeding, maggot feeding, and blood worm feeding) with four replications. The data analysis used was an analysis of variance (ANOVA), which was further tested using the least real difference (BNT). Test parameters include specific weight growth rate, specific length growth rate, absolute length, absolute weight, survival rate, and feed efficiency. The results showed that blood worm feeding significantly affected the parameters of specific weight growth rate, specific length growth rate, absolute length, and absolute weight (P < 0.05). The best growth was found in the bloodworm feeding treatment (specific weight growth rate 4.67 ± 0.31%/day, LPPS 1.88 ± 0.12%/day, absolute length 6.50 ± 0.49 cm, absolute weight 10.26 ± 1.29 g). Artificial and natural feed treatments did not significantly affect survival rate and feed efficiency.

Abstract

Feed is an essential input in aquaculture activities. Feed affects the growth and survival of fish, which can increase the benefits of aquaculture activities. However, the leftover feed can accumulate organic matter from the digestive process and metabolic waste such as feces and inorganic materials such as ammonia, nitrite, and nitrate in the waters. The more feed used, the more organic and inorganic waste accumulates in the aquaculture media. This study aims to analyze the effect of commercial pellet doses on the growth performance of red tilapia (Oreochromis sp.) maintained in the floating net cage (KJA) system in the Mempawah River, West Kalimantan. The study was conducted experimentally using a completely randomized design (CRD) method with four different feed dose treatments and three replications. Treatment 1 was the provision of a commercial pellet dose of 2%; Treatment 2 was the provision of a commercial pellet dose of 3%; Treatment 3 was the provision of a commercial pellet dose of 4%, and Treatment 4 was the provision of a commercial pellet dose of 5%. Tilapia seeds were maintained with the treatment for 40 days. The results showed that administering a 5% commercial pellet dose gave the best absolute, relative, and daily growth compared to other treatments. The survival rate for tilapia seeds maintained in the floating net cage system was best in treating 3% and 4% feed doses.

Abstract

Farmers frequently face a collapse in white-leg shrimp (Litopenaeus vannamei) production due to disease infection. White spot disease, which was spread by the white spot syndrome virus (WSSV) in Indonesia, is one of the disease outbreaks. Extensive research has been done, including providing immunostimulants to prevent the WSSV outbreak. The application of recombinant viral inhibitor protein (VIP solution) developed by Aquaculture Technology and Development PT Suri Tani Pemuka, Purwakarta, is an innovation to prevent the WSSV outbreak. This study aims to evaluate the administration of VIP solutions to avoid the WSSV outbreak. The treatment consists of control feed (PBS without VIP solution supplementation) and feeds supplemented by VIP solution at 2 mL kg-1 and 5 mL kg-1. The feeding trial used post-larvae shrimp stage 25 (PL25). All the treated shrimp were challenged with WSSV, while positive control shrimp were not given VIP solution feed and were challenged with WSSV. The parameters observed included survival rate (SR), phenoloxidase activity (PO), lysozyme activity, and water quality (temperature, pH, and DO). The results showed that the shrimp-fed VIP solution experienced a significant increase in SR and immune response in the challenge test with WSSV (p <0.05). Supplementing 2 mL kg-1 VIP solution showed higher phenoloxidase activity (p <0.05) and increased SR by 82.50 ± 2.29%. The administration of 2 mL kg-1 VIP Solution for whiteleg shrimp can improve the survival rate and immunity after being challenged with WSSV.

Abstract

Pangasius sp. is a freshwater fish that is a favorite for the community to consume. This study aims to analyze the histopathology of catfish-given bacteria (Rhodobacter sp. and Rhodococcus sp. in aquaculture ponds against the histopathology and occurrence of yellowing in the flesh of catfish (Pangasius sp.). A randomized block design (RAK) was used for the study, with three groups:  A (0.2 mL / L), treatment B (0.5 mL / L), and C (control). The procedure for using photosynthetic bacteria is to mix each treatment dose with 1,000 mL of water and then spread it evenly in the cultivation pond. The study's results showed tissue damage to the liver, kidneys, and spleen organs, which was characterized by hemorrhage, inflammatory cell proliferation, fatty and hydropic degeneration, and Melano Macrophages Aggregate (MMA). Organ tissue damage indicates that environmental conditions or water quality are unsuitable. Unsuitable environmental conditions cause stress, dysfunction, and damage to organs. The use of photosynthetic bacteria has a better effect than without the use of photosynthetic bacteria.

Abstract

The leading cause of the high price of fish feed is the increase in the price of raw feed material. One way to reduce the dependence on relatively expensive raw materials is to utilize alternative raw materials, such as tofu dregs. This research was conducted to evaluate the influence of including tofu dregs in feed on the technical coefficient of tilapia cultivation. This study used a completely randomized design (CRD) with four treatments and three replicates: AP8020 (80% tofu dregs + 20% pellets), AP6040 (60% tofu dregs + 40% pellets), AP4060 (40% tofu dregs + 60% pellets), and K (100% pellets as a control). Duncan's further test was conducted to determine the best treatment between treatments. The results showed that mixing 40% tofu dregs with 60% tilapia pellets (AP4060) could increase the increase in Absolute Length, Absolute Weight Gain, Specific Weight Growth Rate, and feed conversion ratio by 15.80 cm, 291.27 gr, 5.74%, and 0.71, respectively. The conclusion of the study shows that mixing tofu dregs and pellets affects the technical coefficient of tilapia growth compared to the control (100% pellets) in the best treatment AP4060 (40% tofu dregs + 60% pellets).

Abstract

Rivers are surface water flows from upstream to downstream estuaries. The Umban Sari River is a tributary that flows into the Siak River. The activities along the river provide ecological pressure that continues to accumulate downstream. This study was conducted in March-May 2024 using macrobenthos as bioindicators of pollution. The purpose of this study was to determine the abundance, diversity, uniformity, dominance, biomass and ecological status of the Umban Sari River waters based on the ABC (Abundance and Biomass Comparison) macrobenthos curve method. This research uses a survey method by determining sampling stations using purposive sampling consisting of three stations. Macrozoobenthos sampling was carried out 3 times with an interval of once a month (30 Day interval). The results showed that the found 8 macrozoobenthic species consisting of Pila ampullacea, Pomacea canaliculate, Lymnaea rubiginosa, Bellamya sumatrensis, Gyraulus convexiusculus, Indoplanorbis exestus, Melanoides pantherine and Schistosoma sp. The highest abundance of macrozoobenthos was found at station I upstream of the river with an average of 3,685 ind/m2 and the lowest was found at station III downstream of the river with an average of 2,148 ind/m2. The diversity and uniformity of the macrozoobenthos is in the medium category, there are no species that dominate. The highest macrozoobenthic biomass was found at station I upstream of the river with an average of 2,643 gr/m2 and the lowest was found at station III downstream with an average of 2,199 gr/m2. The K-Dominant Hypothesis of the ABC curve in the Umban Sari River is included in the category and condition of an undisturbed and unpolluted ecosystem. However, the dominance of the relative biomass (BR) line was found to be only slightly above the relative abundance (KR) line and was close to overlapping, this indicates that the ecosystem condition is starting to become polluted.
