Influence of physico-chemical parameters on population structure and length-weight relationship of Artemia franciscana
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
The Artemia franciscana populations were found throughout the year in Tuticorin saltpan ecosystem. In order to provide better growth and understanding of brine shrimp A. franciscana, the different ecological and biological parameters were taken out during 4 different seasons from January to December 2014. This study determines the impact of algae on growth and physicochemical parameters on population structure and length-weight of Artemia in different seasons of man-made saltpan habitat and algae fed Artemia culture pond at Tuticorin. Maximum population density of brine shrimp was observed in the monsoon season nauplii 54.91% & 52.77%, juvenile 20.52% & 20.03%, pre-adult 15.31 & 14.48%, male 4.91 & 7.53%, female 4.33 & 5.15% were observed in Station 1 & 2 respectively and decline was observed in summer season. The length was observed to the maximum of 8729.44 (μm) & 9696.00 (μm), and the minimum of 7909.77 (μm) & 8367.11(μm) in Station 1 & Station 2 respectively; maximum weight ranged from 0.007g & 0.009g in Station 1 & Station 2 respectively. The sex- ratio showed that males pre-dominated than females during the entire season in both stations. Based on the present study the growth and abundance of Artemia population were high in station 2 because of the enrichment of the algae supplementation.
