This study was conducted to evaluate the possible utilization of 5 different animal protein sources in juvenile rainbow trout, Oncorhynchus mykiss. Meat and bone meal (MBM), feather meal (FM), squid liver powder (SLP), poultry by-product(PBP) and blood meal (BM) were chosen to be the candidate for the possible ingredients for the dietary fish meal replacer in rainbow trout feed. Six different diets were formulated of isonitrogenous and isocaloric basis of $48\textperthousand$ crude protein and 16.7 kJ/g diet: diet 1, $100\textperthousand$ white fish meal (WFM); diet w, $80\textperthousand$ WFM +20% MBM; diet 3, 80% WFM +20% FM; diet 4, 80% WFM+20% SLP; diet 5, 80% SFM+20% PBP; diet 6, 80% WFM +20% BM. As the dietary protein sources, each diet containing 34.7% of animal protein were supplied by WFM with and without MBM, FM, SLP, PBP or BM and approximately 64.2% of plant protein. After one week of conditioning period, fish averaging 2g were divided into six groups and fed one of the experimental diets for 8 weeks. After eight weeks of feeding trials, there were no significant differences in weight gain and feed conversion ratio among groups of fish fed diet 1, 3, 4, 5 and 6(P>0.05). However, weight gain of fish fed diet 2 were significantly lower than those of fish fed diet 1, 3, 4, 5 and 6(P<0.05). These results indicated that FM, SLP, PBP and BM can be used as a dietary fish meal replacer up to 20% in juvenile rainbow trout.

This experiment was conducted to evaluate the long term effects of dehulled soybean meal (DHSM) as fish meal (FM) replacer in the diet for olive flounder, Paralichthys olivaceus, for 42 wk at a commercial fish farm. The four experimental diets were MP (moist pellet based on raw fish), $DHSM_0$ (fish meal based dry pellet), $DHSM_{30}$ (30% fish meal was replaced by DHSM) and COMD (commercial dry pellet). Fish were fed one of the four diets containing 50% crude protein and 16.7 kJ available energy/kg diet for 42 wk. Fish averaging $3.20{\pm}0.04g$ ($mean{\pm}SD$) were initially distributed to each tank as a group of 6,000 fish reared in a flow-through system. At the end of the experiment, average body weight of fish was $315{\pm}9.3g$ ($mean{\pm}SD$) ). Weight gain (WG) and feed efficiency (FE) of fish fed MP, DHSM0 and DHSM30 showed no significant difference among the diet treatments. However, WG and FE of fish fed MP were significantly higher than those of fish fed COMD (p<0.05). Specific growth rate (SGR), protein efficiency ratio (PER) and survival of fish fed all diets were not significantly different among the dietary treatments. Therefore, these results indicate that DHSM could replace up to 30% white fish meal with amino acid supplementation in olive flounder diets for long-term feeding practice at the commercial farm.

This study was conducted to evaluate the possible utilization and the replacing range of leather meal (LM) or meat and bone meal (MBM) as a fish meal replacer for the dietary animal protein source of growing israeli carp, Cyprinus carpio. Five different diets were formulated on isonitrigenous and isocaloric basis of 38.5% curde protein and 15.3 KJ/g diet. Percentage of the graded levels of replacement of white fish meal (WFM) by LM/MBM on the basis of crude protein were at follows : diet 1, 100% WFM (control) ; diet 2, 75% WFM+25% LM ; diet 3, 50% LM ; diet 4, 75% WFM+25% MBM ; diet 5, 50 WFM+50% MBM and LM or MBM, and approximately 64.5% of plant protein. After one week of conditioning period, fish averaging 10g were divided into five groups and fed one of the experimental diets for 12 weeks. In the first and the second 4 weeks of feeding trials, there were no significant differences in weight gain between two groups of fish fed diet 1 (control) and 2 (P>0.05), while fish fed diet 3, 4 and 5 had a significantly lower body weight gain than fish fed diet 1 (P<0.05). In contrast to those two periods, all diet groups were not significantly different compared to diet 1 in body weight gain during the third 4 weeks of feeding trial (P<0.05). These results indicated that LM and MBM could be used as a fishmeal replacer up to 50% in growing israeli carp.

This study was conducted to evaluate the possible utilization and the replacing range of fish meal analogue (FMA) as a dietary animal protein source for fish meal replacer in fingerling common carp, Cyprinus carpio. Leather meal, meat and bone meal, feather meal, squid liver powder, poultry by product meal, blood meal and amino acids were selected as ingredients for FMA. fish averaging 12.5 g were fed one of five isonitrogenous and isocaloric diets containing fish meal and/or FMA as the dietary animal protein sources. Fish meal protein (0, 20, 40, 60 or 100%) was replaced by the graded level of FMA protein. The feeding trial was conducted for 12 weeks after one week of conditioning period. Percent weight gain of fish fed diets containing 20%, 40% and 60% FMA were not significantly different from that of the fish fed the control diet (P>0.05). Feed conversion ratio of fish fed diets containing 20%, 40%, 60% and 100% FMA were not significantly different from that of fish fed control diet. These findings suggest that replacement of fish meal protein by FMA could be possible up to 60% of fish meal protein in fingerling Israeli carp diets.

The present experiment was conducted to evaluate the efficacy of dietary fermented by-product of mushroom, Pleurotus ostreatus, (FBPM) as a fish meal (FM) replacer in juvenile Amur catfish, Silurus asotus. A total number of 225 fish averaging $5.7{\pm}0.1g$ ($mean{\pm}standard$ deviation) were fed one of the five experimental diets formulated to replace FM with FBPM at 0%, 5%, 10%, 20%, and 30% ($FBPM_0$, $FBPM_5$, $FBPM_{10}$, $FBPM_{20}$, and $FBPM_{30}$, respectively). At the end of eight weeks of the experiment, average weight gain (WG) of fish fed $FBPM_0$ or $FBPM_5$ were significantly higher than those of fish fed $FBPM_{20}$ or $FBPM_{30}$ diets (p<0.05). However, there was no significant differences in WG among the fish fed $FBPM_0$, $FBPM_5$ or $FBPM_{10}$, and between fish fed $FBPM_{10}$ or $FBPM_{20}$, and also between those fed $FBPM_{20}$ or $FBPM_{30}$ diets. Lysozyme activity of fish fed $FBPM_0$ or $FBPM_5$ were significantly higher than those of fish fed $FBPM_{10}$, $FBPM_{20}$ or $FBPM_{30}$ diets (p<0.05). The chemiluminescent response of fish fed $FBPM_5$ was significantly higher than those of fish fed $FBPM_0$, $FBPM_{20}$ or $FBPM_{30}$ diets (p<0.05). Broken line regression analysis of WG suggested that the maximal dietary inclusion level for FBPM as a FM replacer could be 6.3% without any adverse effects on whole body composition and on serological characteristics. Therefore, these results may indicate that the maximal dietary inclusion level of FBPM as a FM replacer could be 6.3% in juvenile Amur catfish.

This study was carried out to evaluate the utilization of fermented skipjack tuna viscera (FSTV) in the diet for juvenile abalone Haliotis discus hannai. Lactobacillus bulgaricus was used for fermentation of skipjack tuna viscera. Eight isonitrogenous (about 30% crude protein) diets were formulated to include different levels (0%, 10%, 20% and 30%) of FSTV as a replacer of either dietary fish meal or soybean meal. Three replicate groups of abalone were fed the experimental diets containing different levels of FSTV for 7 weeks. The inclusion of FSTV up to 30% in fish meal-based diet had no significant effect on survival, body weight, shell growth, and proximate composition of abalone (P>0.05). Weight gain of abalone fed the diet substituting 10% FSTV for soybean meal was not significantly different to that of abalone fed the control diet, however this value decreased in abalone fed the 20% and 30% FSTV (P<0.05).The contents of crude protein and lipid of soft body in abalone fed soybean meal-based diets were significantly affected by dietary FSTV level (P<0.05). The results of this study indicate that FSTV can be used as a partial substitute protein source for fish meal or soybean meal in the formulated diet for juvenile abalone.

This study evaluated the possible utilization and the replacing range of animal by-product mixture (ABPM) as a dietary fish meal replacer in growing common carp (Cyprinus carpio). ABPM is a mixture of leather meal, meat and bone meal, blood meal and squid liver powder at a specific weight based ratio. Five different diets were formulated on isonitrogenous and isocaloric basis of $40\%$ crude protein and 15.3 KJ/g diet in which white fish meal (WFM) protein was substituted with the ABPM Protein as follows: diet 1, $100\%$ WFM ($0\%$ ABPM, control); diet 2, $75\%$ WFM+$25\%$ ABPM ($25\%$ ABPM); diet $3,\;50\%$ WFM+$50\%$ ABPM ($50\%$ ABPM); diet 4 $25\%$ WFM+$75\%$ ABPM ($75\%$ ABPM); diet $5.0\%$ WFM+$100\%$ ABPM ($100\%$ ABPM). As the dietary protein sources, each diet contained $34.7\%$ of animal protein supplied by white fish meal and/or ABPM and $65.3\%$ of plant protein. After one week of conditioning period, fish averaging 10 g were randomly assigned to each diet treatment as triplicate groups and fed one of the experimental diets for 12 weeks. Weight gain of fish fed diet 1 (control) and 3 were significantly higher than those of fish fed diet 2, 4 and 5 during the first 4 weeks (P< 0.05), while there were no significant differences among all diet groups during the third 4 weeks (P>0.05). Feed conversion ratio of fish fed diet 1 was significantly higher than those fed diet 2, 3, 4 and 5 during the second 4 weeks (P<0.05), while there were no significant differences among all diet groups during the first and the third 4 weeks (P<0.05). There were no significant differences in proximate analysis among fish fed the experimental diets either for the second 4 weeks or the third 4 weeks (P>0.05). These results indicated that ABPM could be used as a fish meal replacer up to $100\%$ in growing common carp.

A feeding trial was conducted to investigate the effects of dietary fish meal replacement by a blend of lysine cell mass, corn protein concentrate and poultry by-product meal on the growth and blood chemistry of the starry flounder Platichthys stellatus. The fish meal replacer (FMR) was prepared to have the same level of protein as fish meal (FM). With a commercial diet as a positive control, five experimental diets (basal, FM42, FM32, FM22 and FM12) were formulated to contain 52% protein and 10% lipid. The dietary FM levels decreased from 52% (basal) to 42, 32, 22 and 12% with concomitant increase in the FMR to 10, 20, 30, 40 and 50%, respectively. Juvenile starry flounder with an average body weight of 177.3 g were randomly distributed in each (30 fish/tank) of 18 plastic tanks ($139{\times}99{\times}54cm$). After a 45-day feeding trial, the survival rate ranged from 95.6% (FM22) to 100% (control and FM42), while the weight gain of the fish groups varied from 49.7 to 58.4 g. The results clearly revealed that starry flounder can grow well on a diet containing low FM (12%) with a high level of FMR (50%) without any adverse effects.
