Abstract

The success of the tiger prawn seeding business is the first step in the cultivation chain system that will support the business of providing quality seeds. One of the factors that really determines the quality of shrimp seeds is the quality and quantity of feed. This study aims to determine the appropriate dose ratio of natural feed and artificial feed for the growth of tiger prawns in the post larval stage. This research was conducted in September 2020. This study used a Completely Randomized Design (CRD) which consisted of 3 treatments 20 artemia/larvae, 25 artemia/larvae, 30 artemia/larvae. Each treatment was repeated three times. Parameters tested included absolute weight growth, absolute body length, feed efficiency, survival rate, and water quality. Data analysis used ANOVA to see the significance of the effect on the growth of absolute body weight, absolute body length, feed efficiency, survival rate and water quality were analyzed descriptively. The highest average absolute weight growth was obtained in treatment C (0.8 gram) then treatment B (0.65 gram) and the lowest was in treatment A (0.62 gram). The highest mean absolute body length was obtained in treatment C (6.6 mm), then B (5.4 mm) and the lowest was in treatment A (4.3 mm). The highest average value of feed efficiency was in treatment C (9.25%) followed by treatment B (7.56%) and the lowest in A (7.17%). The highest average survival value of tiger shrimp post larvae was obtained in treatment C (77%), followed by treatment B (67%) and the lowest in treatment A (19%). In general, the dose of artemia 30 heads/post larvae was the best treatment with an average weight (0.8 gram), body length (6.6 mm), feed efficiency (9.25%) and survival rate (77%).Keywords: artemia, survival rate, growth, tiger shrimp

Abstract

Freshwater crayfish (Cherax quadricarinatus) are among the most economically valuable aquaculture species, with strong market potential in both domestic and international markets. However, one of the major challenges in freshwater crayfish farming is the deterioration of water quality caused by the accumulation of uneaten feed and metabolic waste. This study aimed to evaluate the effects of combinations of organic materials used as bioremediation agents on the absolute weight growth and specific length growth rate of freshwater crayfish. The experiment was conducted from August to September 2025 at CV. Cova Aquaculture using a Completely Randomized Design (CRD) consisting of four treatments with three replicates each (12 experimental units) over a 30-day culture period. The treatments consisted of powdered dried Indian almond leaves (Terminalia catappa) applied alone as the control (Treatment A), combined with spinach powder (Treatment B), pumpkin powder (Treatment C), or bean sprout powder (Treatment D). The organic materials were applied every three days and after each water exchange. Data were analyzed using one-way analysis of variance (ANOVA). Water quality parameters, including temperature, dissolved oxygen, and pH, were monitored daily. The results showed that the highest absolute weight growth and specific length growth rate were obtained in Treatment C, with an absolute weight gain of 0.78 g and a specific length growth rate of 2.16% day⁻¹. The combination of dried Indian almond leaf powder and pumpkin powder may function not only as an indirect itional supplement but also as an environmentally friendly bioremediation strategy that helps maintain water quality, thereby supporting the sustainable culture of freshwater crayfish.
