This resource was monitored at Veraval, Bombay, Karwar, Calicut, Cochin, Tuticorin, Mandapam, Madras, Visakhapatnam and Kakinada Research Centres. Bulk of the catch is taken by the trawl but considerable landings take place by other gears like gillnet and dol net in certain regions particularly off Maharashtra and Gujarat. The estimated annual landings of croakers during 1996-98 were 161080 t and 158270 t and 199740 t respectively. The landing in 1998 was the highest so far and this is brought out by the increased landings in Maharashtra and Gujarat. Protonibea diacanthus, Otolithus cuvieri, Johnieops sina, Nibea maculata, Pennahia macrophthalmus, Johnius carutta, J. vogleri, J. macrorhynus are the dominant species along different regions of the Indian coast. Data on species landed, Length composition of catch of the dominant species and aspects of biology such as maturation, spawning, and food are collected and processed.

Lizard fish
Lizardfishes are Caught mainly in trawls, they are dominated by Saurida tumbil off Veraval, Bombay and Calicut, S. undosquamis at Cochin, Madras and Visakhapatnam. Other species represented in stray numbers were Synodontus englemanni and Trachynocephalus myops off Cochin and Saurida micropectoralis off Visakhapatnam. A very clear demarcation in regional species distribution is evident in this group. Lizardfish’s with an annual catch of 30055 t and 20528 t contributed to 1.24% and 0.77% of the total marine fish landings during 1996 and '97.
The length range of Saurida tumbil along the Gujarat coast is 165-495mm, in Maharashtra 65-335mm and in Kerala 225-465mm. In S. undosquamis, in the catch off Maharshtra the length range of 125-225mm is dominant, 185-265 mm along Kerala and 125-205 mm along Tamilnadu.

Bull’s Eye
This is an emerging demersal fishery resource. The fishes are exploited mainly in trawls at depths greater than 50 m and the major species is Priacanthus hamrur, P. macracanthus, P. tayenes, P. cruentatus, lookeolus boops. This resource is exploited mainly along the southwest coast and northwest coast. Biology of the species studied indicated their carnivorous feeding habit with extended spawning periodicity .

Pomfrets are landed in large quantities along Maharashtra and Gujarat in gillnets, especially during October-December. Pampus argenteus and Formio niger are the dominant species in the fishery at different regions. Satpathi along the Maharashtra coast is the most important landing center for pomfrets along the entire Indian coast.

Flat fishes
Cynoglossus macrostomus was the dominant species at Mangalore and Malpe, while at Calicut, C. macrolepidotus and at Vizhinjam, C. bileneatus was the major species. Flat fishes are observed to have a distinct species distribution pattern. Cynoglossus macrostomus dominates the landings along the north Kerala-south canara coast (90% of the flatfish landing) whereas C. bilineatus along the south Kerala and C. macrolepidotus in the Gulf of Mannar. Along the southwest coast the length range of C. macrostomus is 50-170mm
