| Abstract: | The paper deals with growth of Japanese anchovy (Engraulis japonicus) and variations in length by area and maturity of anchovy and some selected fish species obtained during surveys with R/V “Bei Dou” in the Yellow Sea and East China Sea,in 1984-1999.Demersal trawl catch rates for some selected fish species from the same surveys are also included.No density-dependent growth in length or weight of anchovy was found.Reduced length at maturity of small yellow croaker was apparent from 1986 to 1994. |
