Mangroves as a habitat for fish and prawns

Mangrove inlets and creeks in Selangor, Malaysia are the habitat for 119 species of fish and 9 species of prawns. The majority of fish and all prawns sampled in the inlets were juveniles. The common fish species in the inlets in terms of weight wereArius sagor, Ambassis gymnocephalus, Liza subviridis, Toxotes jaculator, Sphyraena barracuda andLates calcarifer. Prawns were represented by juvenilePenaeus penicillatus, P. merguiensis, P. indicus, Metapenaeus brevicornis andM. affinis. Samples from enclosure traps set on mudflats during ebbing water captured 37 species of fish and 11 species of prawns. The role of mangroves as nursery and feeding grounds for fish and prawns is reviewed in the light of recent work in Selangor. It is apparent that mangroves support fisheries by providing habitat and food

Redescriptions of Armigeres annulipalpis and Armigeres flavus (Diptera: Culicidae) from Sarawak, Malaysia

Redescriptions and illustrations of the pupae and larvae of Armigeres (Leicesteria) annulipalpis (Theobald) and Ar. (Lei.) flavus (Leicester) were made based on the specimens collected in Sarawak, Malaysia. Illustrations of abdominal ornamentation of adults and male genitalia were also given. The larvae of Ar. annulipalpis were found mainly in water accumulation of green bamboo stumps and splits. Armigeres flavus was commonly found in bamboo stumps and containers with very turbid water in mountain forests
