Autores: Le Foll, Didier; Latrouite, Daniel; Noel, Philippe.
For the analysis of spider crab populations it is necessary to split the size composition by sex and between age groups, and to convert length to weight. In some cases different length measurements need to be correlated in order to compare the results from different authors. Morphometricaly it is easy to use the abdominal flap to distinguish between male and female, and between immature and adult females, but for immature and adult males it is necessary to use Somertons method to analyse the relation between carapace length and claw width. The relation between carapace length and weight is normally established at moult stage 4, and it obtained separately for males, females, immature and adults spider crabs. When measuring carapace length the present length...

Autores: Martin, Jocelyne; Planque, Benjamin.
Long-term monitoring of zooplankton and temperature has been carried out at the nuclear power station of Flamanville (west coast of Cotentin, English Channel, France) since 1977. Zooplankton sampling and temperature measurements took place at fortnightly intervals, particularly during the spring and summer. In addition, daily records of water temperature were recorded since 1986. The seasonal appearance of Maja brachydactyla Balss, 1922 first stage zoeae in the plankton outside the thermal plume near to the power station can greatly vary from year-to-year. Earliest observations have occurred in early June whilst latest observations were made at the end of July. During the period of study, temperature records display a warming trend whilst hatching is...
