    Abstract

    In this lecture we are looking into the relevance of taxonomy while doing numerical modelling studies for identifying essential fish habitats. In order to develop a scientific system for developing the closed area approach, numerical models with outputs in integrated geographical information systems are used as decision supports in rightly identifying the essential fish habitats. Befitting to the fundamentals in the fisheries management concepts, numerical models are resorted for easily re-looking the fishing grounds, breeding areas and nursery areas relevant for a fish in a study domain. But while doing the simulation process, we often tend to make assumptions with respect to the biology and physiology of the fish. In this training lecture we will be looking into the taxonomic requirements which are useful in ascertaining the biological and physiological features of fish while doing a simulation experiment. Sciaenid’s commonly known as drums or croakers are taken as an example while simulating the larval movement of them in Gulf of Kachchh (GoK) using MIKE-21 model – a combination of hydrodynamic and particle tracking model. The model was resorted to know the amount of fish larvae retained at a particular site in the entire domain during the simulation study.
