Use of the Daily Egg Production Method for Estimating Biomass of Clupeoid Fishes: A Review and Evaluation
Abstract:Since its first application to the northern anchovy of the California Current in 1980, the Daily Egg Production Method (DEPM) has been used successfully for anchovies and sardines of other regions, such as the Humboldt Current off Peru, the upwelling systems off Portugal and Spain, the Bay of Biscay, and the upwelling region off South Africa. Parts of the method, e.g., determination of batch fecundity and spawning frequency, have been applied to many other anchovy and sardine species. In addition, application of the DEPM has given us new insight into the reproductive biology of multiple spawning pelagic fish. The worldwide use of the DEPM for clupeoid fishes is reviewed and the advantages and problems encountered when applying it are identified.
