Abstract

Development of a sound data base in inland fisheries  has been receiving attention in the recent past. To  build, up a reliable data base, it is essential that data  collection and estimation methodology is evolved  based on scientific lines and the same is put to  practice for assessing the nature and quantity of  inland fishery resources. Population dynamics deals  with mechanisms of population regulation in an area  and their management practices to analyse the  biomass dynamics of populations. Population  dynamics narrates how the population increase or  decrease over the time, as it is regulated by natality,  mortality, immigration, and emigration. It is helpful  in understanding changing population patterns and  causative issues such as habitat loss, predation and  optimal harvesting rates. An attempt was made to  investigate the population dynamics of economically  important inland fish species of Goa. Primary Data  was collected from the Directorate of fisheries,  Government of Goa web site for the present  assessment, to get the abundance of resources. In the  Present study, data composed of 20 inland captured  fisheries species of which the prawns, clams, mullets  and crabs are among the highest catch and milk fish  0.212, anchovy 0.158, megalops 0.096 , lutianes 0.0827,  black water clams 0.0730 have shown excellent  growth potential during the study period.
