Assessment of Inland Fisheries Population Dynamics in Goa

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.
