COMPARATIVE ANALYSIS OF POND SHAPES IN INTENSIVE CULTURE OF VANNAMEI SHRIMP (Litopenaeus vannamei) FROM PL12 TO DOC50 ON PRODUCTION PERFORMANCE

Abstract

Intensive aquaculture of whiteleg shrimp (Litopenaeus vannamei) often encounters technical challenges due to high stocking densities, making pond design a critical factor in optimizing production. This study aimed to evaluate the effect of pond shape—round tarpaulin versus rectangular concrete—on the production performance of L. vannamei cultured from PL12 to DOC50. The research was conducted at UD. Hidayah Vaname, Probolinggo, using a quantitative descriptive method and comparative approach. Six ponds were used as experimental units (three round and three rectangular), each stocked with 92,400 post-larvae. Data were analyzed using the Shapiro-Wilk normality test and paired sample t-test. The results showed that average shrimp production in rectangular ponds (227.43 kg) was higher than in round ponds (182.28 kg), although the difference was not statistically significant (p > 0.05). These findings suggest that, under limited-scale intensive farming conditions, pond shape does not significantly affect shrimp production.
