A newly developed computer-based method for the analysis of length-frequency data (ELEFAN I & II) is applied to data on reef fishes. It is shown that the growth of reef fishes often oscillates seasonally, and that adjusting for this effect considerably increases the accuracy of growth parameter estimates. This is also confirmed by a re-analysis of tagging data from the Caribbean.

Laguna de Bay, the largest lake in the Philippines, has a catchment of about 290,000 ha, a surface area of about 90,000 ha, an average depth of 2.8 m and temperatures of 22-34°C, with little or no thermal stratification. Its waters are frequently turbid due to wind-stirred bottom sediments, detritus, inflowing silt-laden streams and dense plankton.
