Studies On Growth And Survival Rate Of Pearl Freshwater Mussel Lamellidens Marginalis During The Culture In A Pond
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 1
Abstract
The culture of Pearl Freshwater Mussel in a pond have been studied for a period of one year (from July 2014 to June 2015) with the data on growth and survival factors and discussed with reference to similar work. During one year, the instantaneous and relative growth rate, and survival rate (%) for the pearl mussels were evaluated. A total of 864 Lamellidens marginalis were collected and the growth (shell length, width, height, weight, tissue weight and total weight) and survival of pearl mussels were measured and recorded on a monthly basis throughout the study. Average shell length, width, height, weight, tissue weight and total weight were 71.90 ± 7.04 mm,, 37.79 ± 3.69 mm, 23.31 ± 2.03 mm, 18.03 ± 6.38 g, 41.58 ± 5.13 g and 59.61 ± 11.08 g respectively. The instantaneous and relative growth rate were calculated and ranged from 0.64 % to 3.14 % and from 36.60 % to 164.45 % respectively. The minimum survival rate was registered as 94% during the month of May 2015. Water quality parameters are also tested during the initial and final culture period which in turn did not affect the growth and survival. Significant increases (P < 0.01) were detected in the shell length, height, width, weight, tissue weight and total weight of mussels at all months during the study using ANOVA.
