Field identification of scombroids from Indian seas
Scombroids are a diverse group of pelagic fishes ranging in size from
about 30 cm to over 3 m in length. Most of them, especially the tunas and
billfishes perform considerable and sometimes even transoceanic migrations.
Being highly valued table fishes, they are of significant importance both as a
commercial and recreational fisher

An appraisal of marine capture fisheries management in India
Through technological advancements and increased adoptionofinnovative fishing methods, Indian marine fisheries
has moved from a subsistence oriented traditional one to an industrial sector with annual fish production presently
stabili zing at around 2.7 million t. The ever-increasing demand for seafood from export and domestic markets has
resulted in intense competition for a maximum share ef the resource by the fishers and resulted in inter-sectoral
conflicts spurred by diminished catch rales. This has led to a situation where, some kind of management of fisheries
has become inevitable

Comparison of the growth of oil sardine Sardinella longiceps Val., off Vishakhapatnam and Malabar coasts
The growth of oil sardine, Sardinella longiceps off Visakhapatnam and Malabar
coast was compared. Hydrological and productivity regimes are found to influence
the growth pattern of oil sardine. Growth pattern of oil sardine exhibited
seasonality, which was more pronounced along the Malabar coast than off
Visakhapatnam
Fishery and biology of tunas in the Indian seas
Tunas and tuna-like fishes belong to 6 genera, viz., Thunnus,
Katsuwonus, Euthynnus, Auxis (tribe Thunnini) and Sarda (bonitos) and
Gymnosarda (tribe Sardini) of the family Scombridae. Tunas are among
the largest, most specialized and commercially important of all fishes
(Collette and Nauen, 1983). They are found in temperate and tropical
oceans around the world and account for a major proportion of the world
fishery products. Tunas are unique among fishes because they possess
body temperature several degrees higher than the ambient waters and
have high metabolic rates that enable them to exhibit extraordinary
growth patterns. They have streamlined bodies and vary extensively in
size, color and fin length. They are fast swimmers capable of traveling
more than 48 km/h (Collette and Nauen, 1983), migratory and have few
predators. They are the second most important item, next only to shrimps,
in the world seafood trade and therefore form specifically targeted
fisheries globally by nations such as France, Spain, Thailand, Taiwan,
Korea, Japan and USA. In the Indian Ocean which contributes 19% of
the world tuna catch, tuna fishing and fisheries have emerged as focal
points to address issues of sustainable development and management
of fishery resources, especially in the context of EEZ regulations,
UNCLOS and other international conventions
Tuna resources of India - their potential and exploitation
The average estimated annual tuna landings during 1995 -2004 along the mainland coast of India was 40,292 t comprising species such as Euthynnus affinis, Auxis thazard, A.rochei, Katsuwonus pelamis, Thunnus tonggol and T .albacares. Regionwise production indicated the southwest coast accounted for nearly 48 % of the tunas followed by the northwest (27 %), southeast (24 %) and northeast (1 %) coasts
Pelagic fisheries of India - Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008
The pelagic fishes live most part of their life in the surface or subsurface waters. This group exhibits
rich species diversity and abundance in the Indian EEZ. Though 240 species constitute the pelagic fisheries
along the Indian coast, it is only about 60 species belonging to 8 groups support major fisheries (Table1).
During the last decade, pelagic finfishes contributed to 46-56% (average: 51%) of the total marine fish
production, of which almost 70% was fished from within the 50 m depth zon
