Abstract

This study investigated the growth response of elvers in tanks fed with different diets from March 1, 2024 to May 31, 2024. The study aimed to evaluate the (a) specific growth rates (both weight and length), (b) feed conversion ratio, and (c) survival rates. The results indicated that Treatment 2 (Taiwan Feeds) and Treatment 1 (China Feeds – Control) exhibited the highest specific growth rates in weight, with Treatment 2 recording 1±3.11 and Treatment 1 recording 0.8±0.40, while Treatment 3 (Formulated Feeds) exhibited the lowest specific growth rate in weight at 0.62±0.33. However, statistical analysis revealed no significant differences (p>0.05) on specific growth rates among all the treatments.  On the other hand, Treatment 2 revealed the highest recorded SGR in terms of length at 1.67±0.19.  Meanwhile, results on Feed Conversion Ratio (FCR) revealed that Treatment 1 with (2.11+0.33) is numerically efficient over the other two treatments. Survival rates for all three treatments were sustained at 100% over the 90-day culture period. These findings contribute valuable insights into optimizing elver growth under different feeding regimes, highlighting the potential efficiency of various feed sources in eel aquaculture at optimum culture environment.
