Effect of fish meal substitution with lima bean meal on growth and feed utilization in common carp fry, <i>Cyprinus carpio</i>

Abstract

An experiment was conducted in an earthen pond in the west region of Cameroon to investigate the level of replacing fish meal (FM) with lima bean meal (LBM) on zootechnic parameters in common carp fry. Four hundred and fifty fish weighing 0.91±0.03 g were divided into five groups of 90 fish each. In control group (LBM-0), fish received normal feed, while in four experimental groups, FM was replaced with LBM at 10%, 20%, 30% and 40% corresponding to LBM-10, LBM-20, LBM-30 and LBM-40. Fish were fed three times daily for 84 days. Every 14 days, fish were harvested for weight determination. The results obtained showed significant increases in weight gain (WG) and specific growth rate (SGR). After 84 days of feeding, fish fed in LBM-40 showed a WG of 6.47 ± 0.48 g and SGR of 2.70 ± 0.11%/d compared to LBM-0 (WG=3.52 ± 0.17 g and SGR=1.95 ± 0.08%/d), corresponding to a significant increases of 58.27% and 27.77% respectively. Concerning feed utilisation, LBM-10 produced the greatest effect with the lowest feed conversion ratio (FCR=0.71±0.05) and the highest protein efficiency ratio (PER=3.54±0.26) compared to LBM-0 (FCR=1.09±0.12 and PER=2.36 ± 0.25). These results showed that FM substitution with LBM improves growth and feed utilization in Cyprinus carpio fry.

Effect of Garcinia kola seeds supplemented diet on growth performance and gonadal development of Oreochromis niloticus juveniles breed in ponds

“…The average values of water quality parameters such as temperature, transparency, pH, dissolved oxygen, nitrite, nitrate, and ammonia monitored throughout the trials were considered as suitable for the survival, normal growth, as well as good general physiology of O. niloticus. These values were in accordance with the findings of Yoo and Lee, 2016, Makori et al 2017and Nyadjeu et al (2018 and could partially justify the absence of mortality observed throughout the study, coupled with experimental fish's apparent good health observed through the results on both the growth and feed utilization.…”

Effects of water hyacinth leaf meal feed on growth and body composition of African catfish, Heterobranchus longifilis, (Valenciennes, 1840)

“…These results indicate that Heterobranchus longifilis juveniles have successfully used nutrients from the hyacinth meal. These results are in agreement with those obtained by some authors (Sivani et al 2013;Staykov et al 2015;Nyadjeu et al 2018) who found that the partial substitution of plant sources in fish diets improved growth performance of fish. Indeed, growth increased with increase in Eichhorniacrassipes leaf meal up to 30% incorporation.…”

Substituting Fish Meal with Pre-Treated Lima Bean Meal on Growth, Feed Utilization and Nutrient Retention in Clarias Gariepinus Fingerlings Reared in Hapa-in-Pond System

“…Results from the current study indicates that substitution of fish meal (FM) with Lima bean meal (LBM) at 25% (D25) and 50% (D50), just like Coppens feed, significantly increased the growth in C. gariepinus fingerlings, compared to those fed with the normal diet and diet in which FM was completely replaced with LBM. These results are in conformity with those obtained by Nyadjeu et al (2018) on the effect of fish meal substitution with Lima bean meal on growth and feed utilization in common carp fry (Cyprinus carpio). Therefore, the results demonstrate that partial substitution of FM with LBM enhances nutrient utilization in C. gariepinus fingerlings, which was reflected in improved weight gain, specific growth rate, feed intake, feed conversion ratio, protein intake, and protein efficiency ratio.…”
