In this study, we examined the effects of the ink of the longfin inshore squid (Doryteuthis pealeii) on two species of predatory fishes, the summer flounder (Paralichthys dentatus) and the sea catfish (Ariopsis felis).
Sea catfish, A riopsis felis (Linnaeus 1766) (male and female, 10-30 cm), were purchased from Gulf Specimen Marine Laboratory, Panacea, Florida.
Natural seawater was used for summer flounder, and artificial seawater (Instant Ocean) was used for sea catfish.
Populations of the Giant Sea Catfish
as well as the Yellow Tail Scad have been deemed as being "fished within sustainable levels and their stock is currently not experiencing heavy fishing pressure," said the Emirates Wildlife Society and World Wildlife Fund (EWS-WWF).
A role of olfaction in schooling of Japanese sea catfish, Plotosus lineatus.
Genetic variation in schools of Japanese sea catfish, Plotosus lineatus (Cyprinida, Plotosidae), and advantages of schooling.
The spawning and the larva rearing of the sea catfish, Plotosus anguillaris.
The black bullhead and sea catfish were collected only by gill net.
They also demonstrated a seasonal pattern for sea catfish and gafftopsail catfish, which were present only from April through November.

Usually the artisanal fishermen capture the pemecou sea catfish in first order intertidal mangrove creeks using non-selective fishing methods such as block nets (mesh size 3 cm) or fish trappings, thereby causing an adverse effect on fish recruitment (Giarrizzo and Krumme 2007b).
Although pemecou sea catfish is an important fishery resource along the Brazilian coast, information on its biology and ecology is still lacking.
