The Relationship Between Shrimp Yields and Intertidal Vegetation (Mangrove) Areas: A Reassessment

Three data sets (one from a worldwide survey, one from Indonesia and one using Philippine data) are combined to derive a single relationship linking penaeid shrimp yield, intertidal vegetation area (mainly mangrove) and latitude. This relationship, being logarithmic, cannot be used to compute precise estimates of shrimp fishery losses, given destruction or reclamation of a given surface area of intertidal vegetation. It gives support, however, to the widely held perception that intertidal vegetation plays a major role in penaeid shrimp recruitment.
