Growth and Body Composition Effects of Tuna Byproduct Meal Substituted for Fish Meal in the Diet of Juvenile Abalone, Haliotis discus

Abstract

The effects on growth and body composition that result from tuna byproduct meal (TBM) substituted for fish meal in the diet of juvenile abalone, Haliotis discus, were determined. One thousand two hundred sixty juvenile abalone were randomly distributed into 18 70‐L plastic rectangular containers. Six experimental diets were prepared in triplicate. The TBM0 diet included 28% fish meal and 13% soybean meal as the protein source. Twenty‐five, 50, 75, and 100% of the fish meal were substituted with TBM. Finally, salted sea tangle was prepared. The essential amino acids, such as isoleucine, lysine, and valine, tended to decrease with the dietary substitution of TBM for fish meal in the experimental diets. The weight gain and specific growth rate (SGR) of abalone that were fed the TBM25 diet were higher than those of abalone that were fed the other diets. The crude protein content of the soft body of the abalone linearly decreased with the dietary substitution of TBM for fish meal. In conclusion, as much as 75% of the fish meal in the diet of abalone can be replaced with TBM without retardation in weight gain and SGR of the abalone when 28% fish meal was included.

“…Higher weight gain and SGR of abalone fed all formulated diets compared to those of abalone fed the dry U. pinnatifida in this study was well supported by other studies showing the nutrition‐balanced formulated diets achieved improvement in growth performance of abalone over the single MA, such as Macrocystis pyrifera Linnaeus, Gracilariopsis bailinae Zhang and Xia, U. pinnatifida or S. japonica (Ansary et al, , ; Bautista‐Teruel & Millamena, ; Cho, Park, Kim, Yoo, & Lee, ; Choi et al, ; Jang et al, ; Jung et al, ; Myung et al, ; Viana, López, & Salas, ). Especially, rice bran was the good alternative source for S. japonica in abalone feed when 200 g/kg S. japonica was included (Kim et al, ).…”

“…Food and vegetable by‐product can be a good source of feed ingredient in formulated feed for aquatic animals including abalone. Different sources of food and crop by‐products, such as tuna by‐product meal (Jung et al, ), tunic meal of sea squirt (Choi et al, ) and rice bran (Kim, Jeong, et al, ; Lee et al, ) for fish meal and MA, have been reported in abalone. Reyes and Fermin () also reported that locally available year‐around terrestrial leaf meal ( Moringa oliefera Lam) and aquatic fern ( Azolla pinnata R.…”

The Value of Alternative Feed Ingredients

“…Various products developed from soybeans have been evaluated, including a soybean protein in gilthead sea bream, Sparus aurata (Kokou et al ); hydrolyzed soy protein in starry flounder, Platichthys stellatus (Song et al ); soy protein concentrate for Nile tilapia, Oreochromis niloticus (Ribeiro et al ); soy peptide in juvenile Japanese flounder, Paralichthys olivaceus (Ragaza et al ); and a gamma‐irradiated and fermented soybean meal in juvenile Caspian brown trout, Salmo trutta caspius (Sotoudeh et al ). Other protein sources evaluated have included tuna byproduct meal in juvenile abalone, Haliotis discus (Jung et al ); grain distiller's dried yeast in rainbow trout, Oncorhynchus mykiss (Sealey et al ), and in juvenile Pacific white shrimp, Litopenaeus vannamei (Achupallas et al ); glandless cottonseed protein in Pacific white shrimp (Siccardi et al ); and cricket meal in African catfish, Clarias gariepinus (Taufek et al ). Various dietary oil sources were evaluated for blunt snout bream, Megalobrama amblycephala (Li et al ), and palm oil in Chu's croaker, Nibea coibor (Huang et al ), and for effects on immunity and resistance to Streptococcus agalactiae (Ferreira et al ).…”

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 ).…”
