Abstract

Vaname shrimp is a fishery commodity with high economic value and a large export contribution. The maintenance period is long enough to make production results need to be considered directly. Feed as an important component that can affect growth, water quality, and production costs needs to be considered properly. The feed management program using blind feeding techniques has shown a significant impact on shrimp growth. The water quality factor does not have such a significant effect, except for ammonia which has increased due to the increase in the mortality rate of diseased shrimp. Water quality management with a blind feeding technique can be controlled with feed tests. The results of this observation were obtained directly from observation and active participation during the implementation of the street vendors.

Abstract

This study evaluated the heated winged beans as a plant-based aquafeed ingredient on growth and enzymatic activity in Java barb fish. This study had four treatments and four replications using the CRD method. Treatments contained heated winged beans in an oven at 110°C for 30 minutes (KO) and an autoclave at 121°C for 30 minutes (KA), non-heated winged beans (KE), and feed without winged beans administration (K). Specific growth rate/SGR, weight gain/WG, feed intake/FI, protein retention/PR, and lipid retention/LR were analyzed using one-way ANOVA, followed by DMRT. The protease enzyme activity (U/ml) of Java barb fish was analyzed descriptively. The SGR and WG had insignificant differences among treatments (p>0.05). In LR and PR, the best value was obtained in KO (82.89±0.96 and 95.67 ± 2.73%). The JKP in KO (107.83 ± 5,24 g) had a higher value than K (64.5 ± 8,19 g, p

Abstract

Winged-bean meal can serve as a substitute for soybean meal in plant-based fish feed, despite its trypsin-inhibitor properties, which can be alleviated through heating processes. This study aimed to explore the potential of winged-bean meal subjected to different heating methods, namely oven (110 °C for 30 minutes) and autoclave (121 °C for 30 minutes), based on proximate analysis and trypsin activity. The study applied three treatments with four replications: oven heating (O), autoclave heating (A), and control (without heating, E). All data were analyzed using analysis of variance and Duncan’s multiple range test to determine the best treatment. Data were also compared to the nutrient requirements of several cultured freshwater fish in Indonesia. Heating treatments improved in vitro trypsin activity (1300 units/O and 1135 units/A vs. 835 units) but reduced protein (29.05±1.96%/A and 31.73±1.52%/O vs. 35.17±0.38%) and moisture contents. Additionally, the O treatment met the standards for aquafeed protein content (27-45%) and potentially fulfilled the protein requirements for catfish (25-40%), Nile tilapia (30-35%), and Java barb (30-32%). Therefore, oven heating presents a viable candidate as an alternative plant-based aquafeed ingredient. Nevertheless, the in vivo application of winged-bean meal as an aquafeed ingredient should be further evaluated to determine whether heating treatment effectively enhances digestive activity, nutrient retention, and growth performance in target fish species.
