Abstract

Squilla mantis shrimp is extremely a good source of high nutritive value making them a very healthy choice for human food. Therefore, the objective of the present study is to examine the relationship between environmental factors and the proximate composition of Squilla mantis (stomatopoda - squillidae):  as an indicator of the impact of climate change. Through measurement of the environmental factors (temperature, salinity, pH value, and dissolved oxygen) measured seasonally, at the same time of proximate composition and biochemical constituents were analyzed seasonally in the muscle tissue of Squilla mantis. The Crude protein, lipid, carbohydrate, calorific value, moisture and ash were quantified in Squilla mantis. The statistical analysis of the results showed that the values of the correlation coefficient for different biochemical composition parameters ranged between very strong positive correlation and very strong negative correlation, the relationships were different; the most influential factor is salinity, followed by dissolved oxygen, followed by temperature and pH. It was clear from this study that the ecological state of these constituents is affected by the alteration of environmental factors as a new indicator of the impact of climate change.
