A study on the effect of different colours of culture tanks in nursery, on the production performance, biochemical composition of flesh and physiological responses of whiteleg shrimp ( Litopenaeus   vannamei )

Abstract

Nursery is an effort to improve the quality and quantity of whiteleg shrimps (Litopenaeus vannamei) post‐larvae, before stocking in growth ponds. The objective of this research is to investigate the effect of coloured culture tanks on whiteleg shrimp production, performance and metabolic activities during nursery stage. The results showed that coloured culture tanks had no significant effect on their growth performance (p > 0.05), but had significant effects on their survival rate (>72%) (p < 0.05) and metabolic activities. Based on this research, the best colours for improving the survival rate and production performance of shrimps are green and blue.

Study of Bottom Substrate Variation in Zero Water Discharge Aquaculture for Mahseer Fish <i>Tor soro</i> Nursery

“…The incorporation of substrate materials such as gravel, plastic plants, and PVC pipes during the rearing of Tor putitora has been found to enhance their predatory abilities [13] and alleviate stress by significantly reducing cortisol and glucose levels [14]. Recent research has focused on utilizing biochemical parameters such as hematocrit, cortisol, red blood cell count, and haemoglobin as stress indicators in organisms [15][16][17][18][19].…”

A Study of Environmentally Friendly Recirculating Aquaculture System on Lobster <i>Panulirus homarus</i> Nursery

“…Alterations in the environmental conditions can lead to an elevation in glucose levels in the crustacean hemolymph as a response to stress [5,7,[21][22][23]. These studies require further observation to investigate other physiological parameters as stress indicators in utilizing different RAS.…”

“…These studies require further observation to investigate other physiological parameters as stress indicators in utilizing different RAS. THC can assess crustaceans' stress [5,7,[22][23][24]. In addition, total protein and hemolymph pH are metabolic variables that can be employed to monitor the stress conditions of crustaceans [7,25].…”
