Further studies on the use of mixed feeding schedules with plant- and animal-based diets for common carp Cyprinus carpio (Linnaeus)

Abstract

A growth trial was conducted on common carp Cyprinus carpio (L.) fry in cement tanks for 100 days in order to test the efficacy of mixed feeding schedules. The diets tested were a fishmeal-based diet (diet D with 30.9% protein) and three Colocasia esculenta-based diets (diet A with 16.7% protein, diet B with 19.7% protein and diet C with 25.8% protein) separately and in three mixed feeding combinations of diet A, B and C with D on alternate 2 days (2A/2D, 2B/2D and 2C/2D, where the numeral indicates the number of days that the particular diet was offered continuously). The results revealed no difference in growth of common carp fed the plant protein-based diets A and B (P > 0.05). Although the fish fed on diets C and D and mixed feeding combinations 2A/2D and 2B/2D performed comparably and higher than those on diets A and B, the schedule 2C/2D resulted in the highest final weight. Specific growth rate, feed conversion ratio and RNA/DNA ratios were the highest in the 2C/2D schedule. Among the mixed feeding schedules, the highest saving in protein and cost was recorded with the 2A/2D schedule, followed by 2B/2D and 2C/2D. An increase in dietary protein led to decreased protein and increased fat deposition in the carcass. An increasing trend in the protease and amylase activities was recorded with increased dietary protein level. The study highlighted the efficient utilization of plant proteins by common carp under mixed feeding schedules.

“…A similar finding was also reported with common carp (Nandeesha et al 1993, 2002, Srikanth et al 1989) and sutchi catfish (Ali et al 2005). This might be a result of the lower energy content of diet A or higher energy content of diet B as reported by Nandeesha et al (2002).…”

Fontes protéicas vegetais na alimentação da carpa húngara

“…A quantidade de gordura depositada nos juvenis de carpa húngara alimentados com a dieta controle (Tabela 4) pode ter sido uma resposta à composição das dietas, uma vez que o teor de extrato etéreo da dieta FCS foi superior aos demais (Tabela 2). Da mesma forma, NANDEESHA et al (2002) afirmam que o maior teor de gordura dos alevinos de carpa comum alimentados com dieta à base de farinha de peixe, em comparação aos farelos vegetais, é relacionado à maior concentração de gordura desse ingrediente.…”

Mini review on Incorporation of Cotton Seed Meal, an Alternative to Fish Meal in Aquaculture Feeds

“…Plant based feeds significantly raises the protein and fat levels in the carcass composition of major carps (Nandeesha et al 1995). Both animal and plant based diets lower the moisture level (Nandeesha et al 2002) and do not show prominent effects on ash contents (Garg et al 2002). In Atlantic cod, phosphorus supplementation in plant protein based diets could replace 50% dietary FM without growth impairment (Albrektsen et al 2006).…”
