This study investigated the effects of replacing fishmeal with Clostridium autoethanogenum protein(CAP)on growth,feed utilization and intestinal histology of largemouth bass(Micropterus salmoides).The control diet contained 350 g/kg fishmeal,and then dietary fishmeal was decreased to 300 g/kg,250 g/kg,200 g/kg,150 g/kg and 100 g/kg by CAP inclusion,respectively(FM-30,FM-25,FM-20,FM-15,FM-10).The largemouth bass(110.0±1.0 g)were fed one of the six diets for 8 *** groups of FM-30,FM-25 and FM-20 showed the similar weight gain(WG)and feed conversion ratio(FCR)to the control(P>0.05),while the WG of FM-10 group was decreased by 15.9%,and FCR increased by 0.12 when compared to the control(P0.05).In conclusion,CAP could replace 150 g/kg fishmeal in diet(350 g/kg fishmeal)without adverse effects on growth,feed utilization and intestinal histology of largemouth bass.

The present study was conducted to estimate the optimum requirement of phosphorus in practical diets for largemouth bass(Micropterus salmoides).Six iso-energetic and iso-nitrogenous diets were formulated with the supplementation of monocalcium phosphate(MCP)of 0,5,10,15,20 and 25 g/kg in basal diet containing 350 g/kg fish meal,*** digestible phosphorus of the six diets was measured as 5.7,6.7,7.8,8.7,9.3 and 10.0 g/kg,*** diet was randomly fed to triplicate groups of 25 juvenile fish(initial body weight,16.0±0.2 g)for 60 *** results showed that weight gain increased,and feed conversion ratio decreased with the increase of dietary *** dietary MCP exceeded 15 g/kg(digestible phosphorus of 8.7 g/kg),the WG and FCR were maintained at the similar *** crude ash,phosphorus and calcium contents in whole body,apparent digestibility of phosphorus and protein retention also increased with the increasing phosphorus level in *** phosphorus and calcium levels and plasma phosphorus showed no further increase when dietary MCP reached 20,20 and 10 g/kg with digestible phosphorus of 9.3,9.3 and 7.8 g/kg,***-line analysis indicated that the digestible phosphorus requirement for largemouth bass were 8.9,8.7 and 9.6 g/kg based on weight gain,feed conversion ratio and vertebral phosphorus *** conclusion,the supplementation of MCP in a diet containing 350 g/kg fish meal improved the growth and feed utilization of largemouth bass,and the digestible phosphorus requirement was suggested to be 8.7–8.9 g/kg with MCP supplementation of 15.0–15.8 g/kg.

A 12-week feeding trial was conducted to evaluate the effects of replacing fish meal by chicken haemoglobin powder in largemouth bass *** isonitrogenous(48%)and isolipidic(12%)diets were formulated to replace 0%(control),9.80%,19.61%and 29.41%of fish meal with chicken haemoglobin *** diet was fed to triplicate groups of fish(initial weight:49.50±0.07 g)twice *** fish specific growth rate was significantly reduced when diet replacement level was up to 19.61%,which may be related to the feed intake and apparent digestibility coefficient of protein and amino ***,the feed efficiency ratio and protein efficiency ratio were not significantly decreased until the replacement level up to 29.41%.The activity of CCP was significantly reduced when 19.61%of fish meal was ***,the activity of lysozyme and serum protein content was significantly altered in fish fed with the diets up to 29.41%***,the red blood cell count and haemoglobin content was significantly decreased when the replacement level was up to 19.61%.In overall,the diet with 9.80%of chicken haemoglobin powder was more suitable for largemouth bass.
