| Abstract |
Crangon crangon has a spawning period of about 46 weeks, and berried females with ripe eggs are present in all months of the year although their numbers vary greatly. For this study, the numbers of ripe eggs present in each month of the years 1978-1980 in the shrimp populations in 4 main areas of the coastal zone of the Netherlands and Belgium were correlated with the subsequent changes in the abundance of adult shrimps. The difference between large "winter" eggs spawned in relatively small numbers, and more numerous but smaller "summer" eggs produced by the same stock was studied in effects to stock-recruitment relations and biological relevance |
