Abstract

This study aims to evaluate the application of animal welfare principles in the cultivation of whiteleg shrimp (Litopenaeus vannamei) in the ponds of CV. Anugrah Abadi Perkasa with different stocking densities. This study was motivated by the increasing global market demand for animal welfare standards in aquaculture, while its application in Indonesia is still limited. The method used is descriptive quantitative through direct observation and measurement of observed parameters, as well as active participation supported by documentation. Animal welfare assessment uses a non-invasive approach based on four main indicators, namely environment, nutrition, health, and behavior. The results show that the implementation of animal welfare at CV. Anugrah Abadi Perkasa has been running well in all research plots. The applied cultivation management, such as feed management, water quality control, and disease prevention are able to support optimal shrimp growth and survival. Most of the observed indicators are in the good welfare category. The assessment of nutritional and behavioral indicators in all four plots obtained a score of 1 (good welfare). For environmental and health indicators, the assessment score of 1 (good welfare) is found in plots 1 and 3 with low stocking densities. A score of 2 (tolerable welfare) was found in plots 2 and 4 with high stocking densities, indicating that these conditions are still within tolerable limits, but indicate a decline in environmental quality and health, potentially affecting shrimp growth and survival. This study recommends optimal stocking density management, improved shrimp health management, strengthened animal welfare principles, and the development of more comprehensive evaluation indicators to support the sustainability of whiteleg shrimp farming in Indonesia.

Abstract

Tilapia (Oreochromis niloticus) aquaculture has high economic value and rapid growth; however, the high cost of commercial feed necessitates the use of more economical and nutritionally adequate alternative feed ingredients, such as fermented papaya leaves (Carica papaya). This study aimed to evaluate the effect of different fermentation durations of papaya leaves in commercial feed on the growth and survival rate of tilapia and to determine the optimal fermentation time. This study employed an experimental method using a Completely Randomized Design (CRD) consisting of four treatments and three replications: treatment A (control without fermentation), treatment B (3 days fermentation), treatment C (5 days fermentation), and treatment D (7 days fermentation). Tilapia fingerlings measuring ±5–7 cm with an initial weight of ±3–4 g were reared for 30 days at a stocking density of 20 fish per tank. The observed parameters included weight gain and survival rate, while the water quality parameters measured were temperature, pH, dissolved oxygen (DO), and ammonia. The data were analyzed using a One-Way ANOVA test followed by Duncan’s multiple range test. The results showed that the addition of fermented papaya leaves had a significant effect (P < 0.05) on the weight gain of tilapia, but no significant effect (P > 0.05) on the survival rate. The best treatment was obtained at 7 days of fermentation, with an average weight gain of 19.53 g and a survival rate of 100%. Therefore, a fermentation duration of 7 days for papaya leaves in commercial feed is considered the most optimal time to enhance the growth of tilapia without affecting their survival rate.
