Replacement of Dietary Fish Meal with Poultry By‐product Meal and Soybean Meal for Golden Pompano, Trachinotus ovatus, Reared in Net Pens

Abstract

Two 8‐wk feeding trials were conducted to examine the effect of replacing dietary fish meal with poultry by‐product meal (PBM) and soybean meal (SBM) on growth, feed utilization, body composition, and wastes output of juvenile golden pompano, Trachinotus ovatus (initial body weight 16.7 g), reared in net pens. A control diet (C) was formulated to contain 35% fish meal. In Trial I, dietary fish meal level was reduced to 21, 14, 7, and 0% by replacing 40, 60, 80, and 100% of the fish meal in diet C with PBM. The weight gain (WG), nitrogen retention efficiency (NRE), and energy retention efficiency (ERE) decreased, while the feed conversion ratio (FCR) and total waste output of nitrogen (TNW) increased, with the fish meal level reducing from 35 to 21%. No significant differences were found in the hepatosomatic index, viscersomatic index, and body composition between fish fed diet C and test diets. In Trial II, a 2 × 2 layout was established, and 40 and 60% of the fish meal in diet C was replaced by either PBM or SBM. At the same fish meal replacement level, the WG and NRE were higher and the FCR and TNW were lower in fish fed the diets with fish meal replaced by PBM than in fish fed the diets with fish meal replaced by SBM. The results of this study indicate that more than 21% fish meal must be retained in diets for golden pompano when PBM or SBM is used alone as a fish meal substitute.

The suitable dose of gamma irradiation on soybean meal as a fish meal substitute in diets for golden pompano (Trachinotus ovatus)

“…The FI was more in fish fed diet C than in fish fed diet R0. This result is inconsistent with the conclusion that replacing fish meal with soybean meal affects diet palatability and fish growth (Wang et al 2006;Ma et al 2014). Mani and Chandra (2003) reported that gamma irradiation on soybean cannot significantly affect FI of barbari kids, but improve FCR and nitrogen utilization efficiency.…”

“…This result confirms the conclusion that replacement of fish meal with soybean meal generally causes the increase in nitrogenous pollution in golden pompano farming (Ma et al . ), and indicates that gamma irradiation treatment cannot reduce nitrogen waste outputs of fish fed the diets with fish meal replaced by soybean meal. The NRE (21–23%) was lower, while the NWO [88–109 g N·(kg fish gain) −1 ] was higher in the golden pompano farming than in the malarbar grouper farming (Wang, Li, Han, Zheng & Bureau ) and Japanese croaker farming (Chai, Ji, Han, Dai & Wang ), suggesting that golden pompano may be more sensitive to environmental stress.…”

Supplementations of poultry by-product meal and selenium yeast increase fish meal replacement by soybean meal in golden pompano (Trachinotus ovatus ) diet

“…Golden pompano Trachinotus ovatus is widely cultured along the coast of the South China Sea (Wang, Han, Wang & Ma ). This fish requires more than 210 g kg −1 dietary fish meal when PBM, SBM or soy protein concentrate are used alone as a fish meal subsitute (Ma, Wang, Han, Wang & Lin ; Wu, Han, Qin & Wang ). Recently, the requirment of selenium (Se) in fish nutrtion has been recognized, as Se is an essential constituent of various enzymes with important physiological functions (Yoshida, Haratake, Fuchigami & Nakayama ).…”

Showcasing Research Focusing on Sustainability of Aquaculture Enterprises and Global Food Security

“…Research has indeed focused substantially on developing solutions to reduce or eliminate the adverse environmental impacts of aquaculture, and recently published articles in JWAS are noteworthy examples. For example, work continues on identifying appropriate substitutes for the use of fish meal in diets for a wide variety of aquaculture species (recent examples in JWAS include: Abdul‐Halim et al ; Ma et al ; Moxley et al ; Rossi and Davis ; Kokou et al ; Sealey et al ; Jung et al ; Song et al ). Nutritional research has begun to advance knowledge on the application of prebiotics and probiotics to improve health via the microbiome communities in the gastrointestinal tract of farmed fish and that may lead to elimination of subtherapeutic levels of antibiotic and chemical treatments to control disease (in JWAS , see Mohapatra et al ; Xu et al ; and Peredo et al ).…”
