Abstract

The high price of fish meal is also a reason for alternatives and better protein sources. This research aims to substitute fish meal with maggot meal in feed for snakehead fish's growth rate and survival. The method used in this research is the experimental method of Completely Randomized Design (CRD), which consists of five treatments and three replications. The treatments used were (A) without the use of maggot flour (control), (B) 15% maggot flour substitution, (C) 30% maggot flour substitution, (D) 45% maggot flour substitution, (E) 60% maggot flour substitution, which was maintained for 50 days. The test fish used were snakehead fish with a 9-10 cm length and weighing 7-9 g. The container used is an aquarium with dimensions of 40x26x28 cm3 or a water volume of 15 L, in which five snakehead fish are placed in each aquarium. The amount of feed given is 5% of the fish biomass. The results obtained during the research showed that treatment E with the substitution of fishmeal for maggot meal at 60% of the feed resulted in the highest absolute length growth of 4.0 cm, the highest specific growth rate of 2.54%, and survival of 87%.

Abstract

Online applications are something that currently cannot be separated from people's lives, especially urban communities. The opportunity to utilize online applications is also applied in food sales based on the use of online applications, especially for sellers in the category of Micro, Small and Medium Enterprises (MSMEs). Activities that utilize online applications are called Electronic Commerce (E-Commerce) where physical contact is not required between sellers and buyers. Online applications are one of the things that can support economic progress, but the use of online applications for sales is still limited depending on the area, areas with poor internet conditions usually rarely use online applications for sales. The purpose of this study was to determine how much the marketing of fishery products (Pecel lele) using online applications along the Jatinangor highway which is an area with a high percentage of students and high potential for internet use. The conclusion of this study shows that most of the pecel lele stalls along Jalan Raya Jatinangor have used online applications for sales and fifty percent of pecel lele stalls stated that turnover from using online applications tends to be higher than conventional sales. The conclusion of this study is that in 12 catfish pecel stalls located along the Jatinangor highway, 75% of all stalls have online applications for sales and 25% do not have online applications for sales. In the turnover obtained, 6 out of 12 catfish pecel stalls get higher turnover profits, 3 out of 12 catfish pecel stalls have decreasing turnover profits, the remaining 3 stalls that do not use online applications do not experience changes in turnover profits, namely sales do not increase or decrease.

Abstract

This study aims to determine the most preferred percentage of indian mackerel surimi addition to mantou based on panelist evaluations. The research was conducted from December 2024 to March 2025 using an experimental method with four treatments (0%, 20%, 30%, and 40%) and 20 panelist as the retest. Panelist acceptance was assessed using a hedonic test and Bayes analysis. The hedonic test data were analyzed using the Friedman test. The most preferred mantou sample was further analyzed for its nutritional content through proximate analysis. The results showed no significant differences among treatments in terms of panelist preference. However, the control mantou (0%) and the mantou with 40% Indian mackerel surimi addition had the highest preference scores. The 40% treatment received the highest mean score for appearance (7.90), while the A (0%) control sample scored highest for aroma (8.10) and taste (8.00). Both treatments had the same texture score (7.80). The highest alternative value in the Bayes test was obtained by treatment D (40%) which amounted to 8.03. Proximate analysis revealed that the addition of mackerel surimi tended to increase the nutritional content of mantou, except for carbohydrates. The , 40% surimi mantou had 39.35% moisture, 1.13% ash, 5.17% fat, 10.49% protein, and 43.86% carbohydrates. Meanwhile, the control mantou contained 31.15% moisture, 0.98% ash, 4.57% fat, 8.28% protein, and 55.02% carbohydrates.

Abstract

The prevention of fish infections caused by Aeromonas sp. bacteria can be achieved using Lactobacillus sp. bacteria. This study aims to identify and analyse the effect of Lactobacillus sp. using the microencapsulation method to treat catfish infected with Aeromonas sp. The identification of Lactobacillus sp. bacteria was conducted through microbiological and molecular tests. After obtaining the test results, the research continued with the application of microencapsulation using the emulsion technique. The impact of this microencapsulation was evaluated on catfish through an experimental approach employing a completely randomised design (CRD), with 10 catfish tested in each experimental aquarium. The study included five treatments, designated as A, B, C, D, and E. Treatment A served as the control, without the administration of Lactobacillus. Treatment B involved the application of Lactobacillus without microencapsulation. Treatments C, D, and E utilised varying doses of Lactobacillus at 0.003, 0.005, and 0.007 g/L, respectively. Each treatment was conducted in triplicate. Microbiological and molecular testing identified encapsulated Lactobacillus sp., specifically Lactobacillus helveticus and Lactobacillus johnsonii. The results indicated that treatment D, comprising a dose of 0.005 g/L of Lactobacillus helveticus and Lactobacillus johnsonii, was the most effective in promoting the healing of catfish infected with Aeromonas hydrophila bacteria.Keywords: Completely randomized design, bacterial infection mitigation, probiotic bacteria, emulsion technique.

Abstract

Insecticides can be used to overcome pest attacks in agricultural and plantation sectors. The botanical insecticide is more widely used because more friendly to the environment than chemical insecticides. Neem is one of the plants that can be used as basic ingredient for botanical insecticides because it contains the compound azadirachtin. Insecticide enter the cultivation area because carried by flowing water. Tilapia is a fish that can be used as a bioindicator of pollution levels, water quality, and changes in the aquatic environment. This study aims to determine the effect of exposure insecticide with azadirachtin active ingredient on growth and survival rate of tilapia. This research was conducted in March and August for the preliminary test and September-October 2022 for the main test at Ciparanje Inland Aquaculture Hatchery, Padjadjaran University. The fish used in this study averaged 6,70 ± 0,014 cm. This study used experimental method, Completely Randomized Design with five treatments and three replications. The treatments used were exposure to insecticides with different doses, namely A(0 ppm), B(26.25 ppm), C(52.5 ppm), D(78.75 ppm), E(105 ppm). Parameters observed included absolute length growth and weight growth, survival rate, and water quality until 28th day. Growth and survival data analyzed using the F test and continued with Duncan's test at the 95% level of confidence. The results showed that exposure insecticide can inhibited growth and affected the survival of tilapia. Treatment C(52.5 ppm) is a safe concentration for the survival of tilapia and the highest growth is the treatment without addition of insecticide.

Abstract

This research aims to examine the effect of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin on the survival and growth of common carp (Cyprinus carpio). The study was conducted from September to October 2022 at the Ciparanje Inland Fisheries Hatchery, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The research method used was an experimental method, and the experimental design employed was a completely randomized design (CRD). The study included six treatments with three replications. The test fish used were Majalaya strain common carp fingerling, measuring 7-8 cm, obtained from the Cibiru Fish Seed Center in Bandung City. The treatments examined in this study were Treatment A (0 ppm), B (12.8 ppm), C (25.6 ppm), D (38.4 ppm), E (51.2 ppm), and F (64 ppm). The insecticides were administered once at the beginning of the research in the water, which served as the maintenance medium, according to the treatment concentrations. The parameters observed were survival rate, growth, and water quality. Observations were conducted for 28 days after the application of the plant-based insecticides. The highest percentage of survival was found in Treatment A (control) at 100%, while the lowest percentage of survival was observed in Treatment F (64 ppm) at 81.7%. The highest absolute length growth was recorded in Treatment A (control) at 2.73 cm, and the lowest absolute length growth was observed in Treatment F (64 ppm) at 1.97 cm. The highest weight growth was observed in Treatment A (control) at 4.2 g, and the lowest absolute weight growth was found in Treatment F (64 ppm) at 2.6 g. The research indicates that the growth and survival of common carp fingerling (Cyprinus carpio) decrease due to the influence of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin.

Abstract

Catfish (Clarias gariepinus) is one of the leading aquaculture commodities in Indonesia, with a production volume reaching 1.01 million tons, accounting for approximately 15% of the national aquaculture output in 2020. The availability of high-quality fry is crucial for the sustainability of catfish farming. This study aims to evaluate the effect of high stocking densities on survival rate, condition factor, and size variation of catfish fry reared in UFBs-RAS. This research was conducted at PUI-PT Nano Powder Functional Universitas Padjadjaran (Jatinangor) from October to November 2023. The study tested catfish fry with lengths of 3–4 cm and weights of 1.2–1.4 g with four densities (10 fish/L, 15 fish/L, 20 fish/L, 25 fish/L). The results indicated that stocking density did not significantly affect the survival rate (P>0.05), but it did have a significant effect on length and weight variation (P<0.05). The condition factor did not show significant differences (P>0.05) between stocking density treatments. Overall, a density of 25 fish/L yielded the best performance within the UFBs-RAS. Therefore, this density is recommended as the optimal stocking rate for catfish fry rearing in this system. These findings suggest that the application of the UFBs-RAS system provides a strategic solution for the aquaculture industry to enhance the efficiency of catfish fry rearing at high stocking densities while maintaining optimal water quality and growth performance, thereby supporting productivity and sustainability in intensive aquaculture systems.

Abstract

This study was aimed to observe the survival rate (SR) and clinical signs, and the acute immune response of Pacific white shrimp (Litopenaeus vannamei), including total hemocyte count (THC), bacterial clearance, and prophenoloxidase (ProPO) activity due to infection with the Vibrio parahaemolyticus bacteria and its metabolites. Shrimp were infected by bacterial isolates with culture media (A), bacterial isolates without culture media (B), and metabolites suspensions from bacterial culture media (C) for 8 hours with observation every 2 hours. The results showed that experimental shrimps in groups A and B showed clinical signs and reduced SR, 24.44% and 62.22%, respectively. Experimental group C still showed the clinical signs but did not cause the mortality (SR 100.00%). The THC did not show significant changes, either based on experimental groups or duration of infection, but all groups tended to show decreasing THC at 8 hours post-infection. Bacterial clearance and ProPO activity also did not show significant differences between experimental groups or duration of infection at 8 hours post-infection. However, there was an increase in bacterial clearance activity at 6 hours post-infection in the experimental groups A and B. Based on the study results, the acute immune response in shrimp from all of the experimental groups did not show significant changes at 8 hours post-infection. However, group A significantly decreased SR compared to groups B and C.
