Influence of shrimp head meal incorporated diet on growth and maturation of goldfish Carassius auratus

Abstract

The present study was carried out to find the influence of shrimp head meal on the growth and gonad maturation of goldfish, Carassius auratus. The experiment was carried out with gold fish juveniles (Average Body Weight - 5.98±0.65g) stocked in troughs and fed with shrimp head meal supplemented diet at two concentrations T1 (10%) and T2 (15%) with control diet for a period of 60 days. Sampling on the growth and histological observation was done within 10th and 30th days respectively. T2 fishes had the highest growth rate and weight (75.03 g) and the control group had immature ova. Generally, both T1 and T2 group fishes had well developed ovary with eggs in Tertiary Vitellogenesis (TVO) stage on the 30th day. Therefore, shrimp head meal incorporated at (15%) diet can give better biological parameters of growth and gonad maturation in goldfishes.
