Effect of fish meal replacement with lentil seed (Lens culinaris) in common carp (Cyprinus carpio) L. diet

Abstract

The aim of this study was to see how replacing fish meal with lentil seeds (LS) as an alternative plant protein source in diets for common carp Cyprinus carpio affected growth performance, feed consumption, and the composition of the fish's proximate carcass. The fish (100-106 g mean initial weight) were fed 0% (LS0), 5% (LS5), 10% (LS10), 15% (LS15) and 20% (LS20) of Lentil seed protein for 10 weeks. With increasing fishmeal replacement with lentil seed in the fish diet, there was a significant (p<0.05) increase in weight gain, relative and specific growth rate. T5 (20% LS) had a significantly (p<0.05) higher feed efficiency ratio and protein efficiency ratio than the other treated groups. There were no significant (p<0.05) differences in the mean values of proximate composition of fish fillets, such as moisture, crude protein, crude lipid and ash. Finally, no significant differences in muscle ratio (weight without viscera vs. weight without viscera & head) were found. The current study found that lentil seed can replace 20% of dietary fish meal in common carp diets for better growth.Keywords: lentil seed, fish meal, common carp, growth performance and feed utilization.

Role of microbial phytases in improving fish health

“…rohita 74 and C. carpio 126 and increased growth was obtained in both the cases. The inclusion of phytase in a methionine-supplemented diet showed a significant improvement in the growth of Chinese sucker (Myxocyprinus asiaticus).…”

Eficiencia de una dieta con base en harina de lenteja (Lens culinaris), en el crecimiento de alevines de tilapia

“…Abdulrahman y Abdulla (2020) y Abdulrahman et al (2021) reportaron que obtuvieron mejor ganancia de peso y talla en adultos de C. carpio con la inclusión del 20 % de harina de L. culinaris con respecto a los demás tratamientos y al control. Estos resultados también fueron obtenidos por Guo (2016) que usó almidón de L. culinaris en reproductores de tilapia, en los que se mostró una mejor eficiencia en los índices productivos.…”

“…lo que se evidencia en este trabajo una asimilación y aprovechamiento del alimento. Sin embargo, con relación a Abdulrahman et al (2021) que trabajó con L. culinaris al 20 %, reportó el 0,34 % en adultos de C. carpio, resultado que está influenciado por la cantidad de proteína encontrada en la dieta, edad y especie del individuo, además que la TEA en alevines es mayor.…”

Use of Natural by Products in Fish Nutrition

“…Significant improvements in fish growth, coloring, reproduction, and flesh quality can be achieved by adding Spirulina platensis to fish diets as a feed supplement or as a partial replacement for fishmeal (Abdulrahman et al 2019). According to the latest research, common carp diets can substitute 20% of their fish meal with lentil seed for improved growth (Abdulrahman et al 2021). Allicin is an active garlic compound that causes increases in diet intake (Zeng et al 1996).…”
