Abstract

Quantitative fish stock assessment has been a subject crossing a century if one strictly goes by the tools and techniques and gets yonder by another 75 years when it comes to its praxis. With assessment and management being viewed as two sides of the same coin, the practice of setting task forces to review the exploitation and related developments dates back to the 19th century. Closely following these developments are the governance interventions like regulations and penalties. Thus, this domain of scientific knowledge with immediate practical relevance is almost as old as any other branch of similar stature. But to anyone having a serious look at this field, it always gives a feel of a subject still nebulous in concept and context. This can be attributed to the type of resource this domain touches, fish. Fishery resources, both marine, brackish water or freshwater, are a bunch of natural resources that have more hidden than what is revealed. When the focus is on marine fisheries, this enigma entangled with surprises is a common sight. Under a thick sheet of water which is contained in a nearly bottomless and brimless container of sorts, identifying, studying, assessing and managing these resources themselves are quite a handful. Be it a researcher or a manager these resources throw up the dichotomy of being too simple to interpret, yet too difficult to manage. Thus logically speaking fish stock assessment is a dynamic admixture of science and art, whose proportions change as per ground reality. If the resources could be successfully brought under the realms of numbers then the science proportion gets to its peak, whilst the existing fishery throws up more diversity in terms of modes, means and status of those earning a livelihood out of this, the dosage of science gives way to what falls under the realms of the art of stakeholder management.
