Population density, biomass and allometric relationship of shortneck clam Paphia malabarica (Chemnitz, 1782) from estuarine regions of Goa, west coast of India
INDIAN JOURNAL OF FISHERIES(2014)
摘要
Studies on morphometry and length-weight relationship of Paphia malabarica were carried out in samples collected during March 2009 to March 2010 at two locations in Goa. Morphometric relationships between length-breadth and length-depth variables were found to be linearly related. However, the relationship between length-total weight, length-shell weight, length-wet weight and length-dry weight showed a nonlinear isometric pattern at both stations. Data also indicated significant spatio-temporal variation in the density, biomass and dimensions among clams at the two sampling stations. The clam population density was compared with relevant physico-chemical parameters and is discussed in the present study. Chlorophyll a of water sample was observed to be the major water quality parameter influencing the density of P. malabarica at both the stations.
