Cynoscion is a genus of umberfishes , which occurs with 24 species in the tropical and warm-temperate areas of the western Atlantic and the eastern Pacific . They mostly inhabit waters near the coast. They are popular food and sport fish , which are known in English as weakfish (soft fish) or seatrout (sea trout)due to their tender meat.
features
Cynoscion species are elongated, spindle-shaped fish with a laterally flattened body and an oval body cross-section. The head is conical with a pointed snout, medium-sized eyes and no barbels or pores. The mouth is large, with hanging corners and a protruding lower jaw. The pointed teeth sit in close rows, a pair of long, pointed fangs sit in the upper jaw. The front cover is smooth-edged. The elongated dorsal fin has six to ten hard rays and one hard and 20 to 30 soft rays behind a deep notch. The anal fin has two short hard rays and 8 to 20 soft rays. The swim bladder has two short, unbranched appendages at its front end.
The species Cynoscion othonopterus, which occurs in the Eastern Pacific, generates click sounds during the breeding season in the area of the Colorado River Delta, which can be up to 150 decibels and are considered to be the loudest noises ever recorded in fish.
