Fishes of the family Priacanthidae are popularly called as big eye or bull’s eye. Priacanthus hamrur is an important deep-water
inhabitant of great commercial value. High percentage of landings of Priancanthidae was used as raw material for surimi, sausage
and other fishery by-products. Presently, it has great demand in Singapore, Thailand, Taiwan, Hong Kong and other countries. For
the maturation studies, samples were collected from commercial landing centre, Mangalore. Studies on reproductive biology showed
that Priacanthus hamrur spawns twice in a year, the spawning season extending fromMarch to May and October to November. Based
on the percentage occurrence of mature fishes in various size groups, it was inferred that male attained maturity at smaller size than
female. This study will enable us to understand the spawning periodicity, cyclic morphological changes in male, female gonads and
also it helps to improve stock size by enforcing fishing ban in particular season by assessing spawning periodicity.

stock assessment, taxonomy of finfish and shellfish, biodiversity of finfish and shellfish, marine fishery resources, anatomy, physiology of finfish and shellfish,
biology of fish, tropical fish stock assessment, Applications of fisheries models in stock assessment and Modern techniques in ichthyotaxonomy. Besides, his role
also includes research work of applied nature related to fisheries resources, their abundance, distribution, assessment and management. In addition, an effective
extension work in fisheries is undertaken as a tool of taking the message from lab to land. Popular articles, interviews through local electronic media, etc., are also
