Abstract

The papaya and pineapple are the major agricultural food products in Thailand. Their by-products contain protease enzyme, papain and bromelain, which can breakdown proteins. The objective of this study was to investigate the growth performances of channel catfish (Ictalurus punctatus) fed with feed mixed with pineapples juice (PA) and dried papaya peel (PP) in a recirculating aquaculture system (RAS). Three experimental feeds controlled at 25% isonitrogenous formulation containing 5 ml/kg feed PA, 5 g/kg feed PP, mixed PP-PA (5 ml/kg) feed pineapple juice mixed with 5 g/kg feed papaya peel (PP-PA) and a commercial control feed were fed to catfish for 90 days. Each treatment had 3 replicates. The channel catfish (5 g/fish) were allocated in 12 (1 x 1 x 1 m) placed in RAS concrete tanks. The water quality in this research was within the recommended nets levels by the Pollution Control Department, Thailand. The results showed that weight gain, length gain, average daily gain, feed conversion efficiency and protein efficiency ratio was highest in catfish fed with PP and which was significantly different (p < 0.05) from control. The survival rate of all treatments was not significantly different (p > 0.05). In conclusion, 5 g of dried papaya peel mixed in the 1 kg of diet could be applied for channel catfish culture to improve growth performances.

Highlights

Channel catfish (Ictalurus punctatus) is the most important aquaculture species in the United States (Tucker and Hargreaves, 2004)
The objective of this study was to determine the growth performances of channel catfish fed with feed mixed with pineapples juice and dried papaya peel
After catfish were cultured for 90 days, the results showed that weight gain was highest in catfish fed with a commercial feed mixed with 5 g/kg feed dried papaya peel (PP), 29.94±0.95 g which was significantly different from the ones in control, a commercial feed mixed with 5 ml/kg crude extract from pineapple (PA) and a commercial feed mixed with 5 ml/kg feed pineapple juice and 5 g/kg feed papaya peel (PP-PA) (p < 0.05)

Summary

Introduction

Channel catfish (Ictalurus punctatus) is the most important aquaculture species in the United States (Tucker and Hargreaves, 2004). The production of channel catfish in the United States, accounting for more than 60% of all aquaculture (Liu et al, 2016). These catfish have introduced to China and Thailand . The systems for channel catfish culture in the United States are various, including ponds, cages, raceways, and tanks (Helfrich and Libey, 2006). RAS filters clean the water, and removes or detoxifies harmful waste products; the recycling water is subsequently back through fish culture tanks (Helfrich and Libey, 1991). RAS is much more suitable for warm water fish cultures such as channel catfish, striped bass, and tilapia that can tolerate lower water quality conditions and high temperatures (Helfrich and Libey, 1991)
