Effort development in German brown shrimp fishery and the attempt to standardize annual landings per unit effort in the period 1976 to 2010Abstract
Brown shrimp is a fastgrowing, shortlived species, and all attempts to use stock assessment methodologies typically applied to other fisheries are usually unsuccessful.Here landings per unit effort data (LPUE) for the German fleet based on a number of effort metrics are used as indices of stock size. Their utility in relation to describing stock development and fisheries management is discussed.LPUE estimates indicate that stock sizes between 1976 and 1989 were relatively stable. In 1990, the lowest reported landings of brown shrimps in Germany coincided with severe economic problems for the shrimp fisheries. From 1990 to 2010 standardised annual indices show that both landings and LPUE estimates have increased at variable rates suggesting large stocks of brown shrimps in recent years.This is discussed in relation to the positive effects of reduced predator abundance and favourable climatic factors.Journal
