Physico-chemical analysis of natural water sources at Thengaipattinam, Kannyakumari District, Tamilnadu, India

摘要

The physico-chemical characteristics are said to play a significant role in the distribution of organisms such as reproduction, and feeding etc. Various physico-chemical and biological processes in the mangals make it a habitat for vast array of organisms, leading to rich biodiversity. Generally fish is considered as a highly protein rich food in relation to vegetable and other animal foods. This fish has a high feed efficiency ratio, but due to its feeding behavior it has bad smells that cause to sell with a lower price. The physico - chemical analysis of water samples was performed by standard methods. The edible freshwater fish Cyprinus carpio are collected from the fish culture pond, the fish are sacrificed by shock treatment, Organoleptic assessment is laid on general appearance, slime formation on the body surface, nature of eye, colour of gills, texture, odour and overall acceptability of the fish is examined followed by the microbial analysis in which the Total heterotrophic bacterial population (THBP) is enumerated in collected fish digestive tract samples. The main parameters which affect the shelf life of the stored fish products are the production form, features of packing material, storage temperature, packing process and machines that are used. Hence, the aim of present study is to develop from common carp (Cyprinus carpio) and to determine the rate and the type of a deterioration process that occurs during the refrigerated and frozen storage using sensory, bacteriological, physicaland chemical assessments.
