  Larval stage of marine fishes, habitat characteristics, nursery and feeding ecology has been discussed in this review. Identification of fish larvae is difficult and that is why limited research is available on biology of fish larvae in the Indo-Pacific coastal region. Estuaries play a vital role in energy transfer between a river and a sea, which is especially important for many commercial coastal fishes whose larvae and juveniles are dependent on the estuary as a nursery and feeding grounds. Many coral reef fish species use mangrove and seagrass beds as nursery habitats. Diet composition of the family Clupeidae were made up of seven major categories to include phytoplankton, plant-like matter, debris, fragment of copepod, algae and unidentified food items. The most predominant food item in the gut of clupeids was phytoplankton (82.53%).

  Diet composition of most common fish larvae of family Sparidae was studied in the Sungai Pulai seagrass bed of Gelang Patah South Western part of Johor, Peninsular Malaysia from December 2007 to May 2008. Larvae were collected by subsurface towing of a bongo net. In situ hydrographic parameters were recorded during the sampling cruises. Stomachs were removed from a total of 80 Sparidae specimens during the study period and the stomach contents were examined. Analysis of prey in the stomach showed 24 important food items belonging to 8 major groups: phytoplankton, zooplankton, algae, insects, plant like matter, decapod appendages, debris and unidentified matters. The predominant food items found in the stomach were phytoplankton (60.85%). This was followed by algae (11.73%), zooplankton (9.35%), plant matters (7.84%), debris (4.60%), insects (2.84%), unidentified matters (1.96%) and decapod appendages (0.82%). Habitat in situ temperatures were recorded at 26.92-30.83°C (Mean± SD, 28.60± 1.38); Dissolved oxygen ranged from 4.73 to 6.24 mg L-1 (5.56± 0.53) and the salinity fluctuation was between 29.37 and 33.68 ppt (31.31± 1.68). Among the food items, phytoplankton was the first rank by Simple resultant index (60.85%) followed by algae (11.73%). Therefore, it could be concluded that the fish larvae of family sparidae are mainly herbivorous.
