This paper explores the possible options for quantitative fishery stock assessment in tropical
waters and is composed of four layers viz., concepts, methodologies, data and indicators.
The concept promotes the fundamental theory that has been popular in research on stock
dynamics, including the possibility of combining it with various doses of intrinsically
biological information, from individual fish to regional stocks. After reviewing the concepts,
tools and their evolution, an attempt has also been made to propose a few guidelines as the
best ways to approach stock assessment and formulate input control or output regulation
strategies in the most pragmatic yet scientific manner, thereby ensuring minimal impact on
the fishery, fishers and stocks in the medium term.
