Effect of strong winds on the nutritional condition of anchovy (Engraulis encrasicolus L.) larvae in the Bay of Biscay, Northeast Atlantic, as inferred from an early field application of the DNA/C index
A new biochemical index was used to assess larval fish nutritional condition during a survey cruise in the Bay of Biscay in early June 1993. This period corresponds to the breeding season of the European anchovy ( Engraulis encrasicolus L.). The analysis of samples taken at grid points indicated a c...

A new biochemical index was used to assess larval fish nutritional condition during a survey cruise in the Bay of Biscay in early June 1993. This period corresponds to the breeding season of the European anchovy ( Engraulis encrasicolus L.). The analysis of samples taken at grid points indicated a clear spatial pattern in nutritional condition, which increased from the middle shelf to the shelf edge. A relatively large fraction of the larval population proved to be in poor condition. Strong winds with speeds of 20–30 knots occurred during 3 d after the first survey and affected the vertical hydrological structure.
