The biochemical composition of red seaweeds,Catenella repens was investigated in this present study along with subsequent analysis of relevant physico-chemical variables.In this study, the relationship between the nutritive components of this species and the ambient environmental parameters was established.Protein content varied from 2.78 ± 0.30% of dry weight (stn.3)to 16.03 ± 0.96% of dry weight (stn.1) with highest values during monsoon.The protein levels were positively correlated with dissolved nitrate content and negatively correlated with water temperature (except stn.3)and salinity.Carbohydrate content of this species varied signiﬁcantly (𝑝 > 0.05) during pre-monsoon between stations and the values showed positive relationship with salinity and surface water temperature.In contrast to carbo- hydrate,lipid concentration was lowest in values and varied very slightly between seasons and stations.Astaxanthin content of the seaweed species was greater in pre-monsoon than monsoon and post-monsoon in all the selected stations.Compared with the three seasons, samples of red seaweed collected in pre-monsoon has high carbohydrate –astaxanthin in contrast to protein –lipid which showed high values during monsoon.Statistical analysis computed among the environmental and biochemical parameters suggests the potential role played by the abiotic parameters on biosynthetic pathways of seaweed.This paper also highlights the inﬂuence of the nutritional quality of water that can be used for mass cultivation of Catenella repens.
