Abstract | Shrimp farming is suffering from slow growth and high feed intake due to the rise of water temperature duringsummer. In this study, physiology and bioenergetics of juvenile Litopenaeus vannamei reared for 4 weeks at ambient (29 ยฐC) andexcessive (33 ยฐC) temperatures were evaluated. Obtained data of feed intake (C), growth rate (P), apparent heat index (AHI),oxygen consumption (R), fecal loss (F), ammonia excretion (U), and molting (M) were converted to energy equivalents. Theresults indicated that growth energy for shrimp (R+AHI+F) at 33 ยฐC was 1.8-fold higher than that of shrimp at 29ยฐC. Mostenergy contents (AHI, R, F, U) reared at 33 ยฐC was significantly higher than that of shrimp at 29ยฐC except M and P. Shrimpreared at 33 ยฐC have lost their weight energy by 14.15 %. This indicated that shrimp reared at excessive temperature sufferedfrom insufficient energy for growth. |
