Lobsters are ubiquitous, economically important decapod crustaceans with apparently conflicting evolutionary relationships. Here, we describe the chromosomal location of major (45S rDNA) and minor (5S ribosomal gene families in four species Astacidea five Achelata, using two-color FISH. The family is located 4–16 sites per diploid chromosome set, Nephrops norvegicus (Nephropidae) showing highes...
This study describes experiments carried out to examine effects of the antiparasitic drug teflubenzuron, used in delousing farmed salmon, on a non-target species, the European lobster (Homarus gammarus). Juvenile lobsters were fed two doses of teflubenzuron, 10 and 20mg/kg successively for 7 days corresponding to a standard medication of the fish (10mg/kg day) and twice the standard dose (20mg/...
Ecophysiological studies on the developing eggs and embryos of the European lobster Homarus gammarus
In the Plymouth area, estuarine decapod crustaceans like Carcinus maenas and Palaemon serratus have much higher concentrations of zinc in the blood than marine species such as Homarus vulgaris and Maia squinado. These differences between species with different powers of osmotic and ionic regulation have not been explained, but they were the starting-point of the present work. This is a study of...
