Hence, they will only develop outside the lagoon, as proved by the observation of zoea I stages exclusively. Main recruitment starts in April, i.e. much later than the first larvae appear. Small crabs prefer Zostera noltii patches and colonize other sites when the carapace width exceeds about...
1.1. The growth (dry weight, W), protein, lipid content and nucleotide composition (ATP, ADP, AMP, UTP and GTP) were estimated at 16°C at daily intervals for growing and starving zoea I of Carcinus maenas.2.2. Larvae fed with Artemia sp. during the entire development moulted at the ...
Larvae of Carcinus maenas L. were reared in the laboratory from hatching through metamorphosis at 9, 12, and 18°C. Dry weight (DW) and elemental contents of carbon (C), nitrogen (N), and hydrogen (H) were analysed at short intervals through successive larval moulting cycles (four zoea-...
In all larval stages of Carcinus maenas L. oxygen consumption was measured at three temperatures (12,18,25 °C). Values increased during development and were in the range of 0.037 ± 0.01 (zoea-1, 12°C, x ± 95% CL) to 0.734 ± 0.047 μl O 2 · h 1 · ind 1 (megalopa, 25...
The following rearing temperatures proved most successful during larval development: (1) embryonic development, 10°C; (2) zoea stages, 15°C; (3) megalopa stage, 17.5°C. The larvae hatch preferably in darkness when reared under short-day conditions....

Improved methods for experimental rearing of Pagurus bernhardus and Carcinus maenas larvae are presented. Isolated maintenance was found essential for reliable statistical evaluation of results obtained from stages older than zoea-1. Only by isolated rearing is it possible to calculate mean values 卤95%...

Lethal and sublethal effects of particular starvation events were investigated in larvae of Carcinusmaenas L. Mean survival times of continuously starved zoeae-1 were approximately twice the normal stage duration (12, 18, 25掳C), and both increased with falling temperatures. At 6掳C zoea-1 was ...
