Abstract
Seven species of catfishes Family:AriidaeArius caelatus A. venosus A. sagor Arius sp. Ketengus typus and Osteogeneosus militaris were sampled by the otter trawl and gill nets in the Matang mangrove waters. In trawls carried out in the mangrove channels A. venosus was abundant 456 ind. ha-1 while A. Caelatus had the highest biomass 11.3kg ha-1. The catfishes were not important in the mudflats and inshore waters. The 3.75 cm 1.5 in. mesh gill net recorded the highest abundance 787 individuals and a biomass of 1.63 kg hr-1 m-1. The day-flood tide combination recorded the highest biomass 11.9 kg ha-1 density 780 ind.ha-1 and catch per unit effort 4640 kg hr-1 values as compared to the other combinations day-ebb night-flood and night-ebb. Of the three most abudant ariids A. venosus had the highest percent of mature females 30 followed by A maculatus 16 and A. caelatus 12. Reasons for their abundance in the mangrove waters are discussed.
