Osmoregulation in decapod larvae as a consideration in culture techniques
Osmoregulation bei Decapoden-Larven und ihre Bedeutung für die Kulturtechnik
Helgoländer wissenschaftliche Meeresuntersuchungen volume 20, pages 697–706 (1970)
Kurzfassung
Die Larven der Decapoden weisen Veränderungen der osmoregulatorischen Fähigkeiten auf, die oft kurzfristiger Art sind und sich zwischen den Häutungsstadien manifestieren. Kurzzeitige Veränderungen der osmoregulatorischen Kapazität können von einem Tage zum anderen zutage treten. Hierfür werden Beispiele anhand von Untersuchungen an den Larven vonCallinectes sapidus, Libinia emarginata undHepatus epheliticus gegeben. Es wird darauf hingewiesen, daß es in vielen Fällen notwendig ist, Kenntnisse über die physiologischen Vorgänge der Osmoregulation zu gewinnen, um diese für die Zucht von Decapoden-Larven nutzen zu können.
Summary
1. Larvae of decapod crustaceans, especially crabs, change their capacity to osmoregulate from day to day and between moult stages.
2. These changes are related to alterations in internal osmoconcentration so that inward flow of water increases body turgor to assist in the moulting process.
3. It is useful, therefore, and often essential, to be aware of these physiological events during the course of culture.
