Identification of groupers available in Indian water
Sea basses are mostly marine in habitat with
widespread occurrence from tropical and temperate
seas. Fishes are characterised by an opercle with
three spines with the main spine in centre and one
each above and below. Body scales are generally
ctenoid with cycloid scales also reported. Lateral line
is continuous, not extending onto caudal fin. Single
continuous dorsal fin, in some with notches, 7- 13
spines. Anal fin with 3 spines; caudal fin usually
rounded, truncate, or lunate. Tip of maxilla exposed,
pelvic fin with one spine and five soft rays; seven
branchiostegal rays usually present
Field Identification of Rays and Some Common Flatfishes of India
This suborder includes all of the Eagle Rays (Myliobatidae), Cownose Rays (Rhinopteridae) and the Mobulid Rays and includes about 40 species which are characterized by diamond shaped bodies and wing-like pectoral fins which they use to propel themselves through open water. Eagle Rays and Cownose Rays feed on the seabed, using their mouths to dig amongst the substrate in search of buried molluscs and crustaceans, while the mobulid rays lead a complete pelagic life. The order has 8 families under it

Field Identification of Groupers and Snappers
Sea basses are mostly marine in habitat with wide spread occurrence from tropical and temperate seas. Fishes are characterised by an opercle with three spines with the main spine in centre and one each above and below. Body scales are generally ctenoid with cycloid scales also reported. Lateral line is continuous, not extending onto caudal fin. Single continuous dorsal fin, in some with notches, 7- 13 spines
Self-Image, Self-Defence and Self-Reverence
Self-image is how you perceive yourself. It is a number of self-impressions that have
built up over time: These self-images can be very positive, giving a person confidence
in their thoughts and actions, or negative, making a person doubtful of their
capabilities and ideas
Flatfish fishery off Cochin and some aspects of the biology and stock of Malabar sole Cynoglossus macrostomus (Norman)
Flatfish landings increased from an estimated 58 t in 2000 to 299 t in 2002, but
declined to 65 t in 2003 and 61 t in 2004 at Cochin. August and September were
the months of peak landings, which were also the peak spawning months. The
optimum length of exploitation was 124 mm. Annual growth coefficient (K) and
L were 0.79 and 212.5 mm respectively. The resource is being exploited at a
level (E = 0.78) higher than the optimum (Emax = 0.458). Appropriate
management measures are discussed
Silverbelly fishery of Palk Bay and Gulf of Mannar with special reference to Leiognathus jonesi (James, 1967)
Silverbellies constitute an important group of demersal fishery resource along Tamilnadu coast. They are explited by trawl and a variety of artisanal gears like shore seines, boat seines and gill nets. The southeast region contributed nearly 85% of the silverbelly landings of india and Tamnadu's share was 70%
