Developmental expression of the octopamine phenotype in lobsters, Homarus americanus.
We have used immunocytochemical methods to examine the sequence of appearance of octopamine-immunoreactive neurons during development, and to try to correlate that appearance with the emergence of behavioral or physiological capabilities. The first octopamine neurons express their transmitter phenotype at approximately 43% of embryonic development. The last cells show immunostaining at the 3rd ...
متن کاملLong-term consequences of agonistic interactions between socially naive juvenile American lobsters (Homarus americanus).
Agonistic behavior of decapod crustaceans occurs in the wild, is highly stereotypical, and is readily quantifiable. Here we explore the persistence of dominance relationships in socially naı̈ve juvenile American lobsters (Homarus americanus) by examining the time frame over which behavior changes as a result of previous fight experience. We paired opponents for three fights: initial; 1 hour late...
متن کاملBait and the susceptibility of American lobsters Homarus americanus to epizootic shell disease.
Shell disease (SD) has been observed in lobster populations for almost a hundred years, but recently, rates of an epizootic form of shell disease (ESD) have increased in the southern New England (USA) area. A large proportion of fish in the diet of American lobsters Homarus americanus has been linked to increased rates of SD. Therefore, the use of fish as lobster bait may be linked to increased...
متن کاملA noninvasive method for in situ determination of mating success in female American lobsters (Homarus americanus).
Despite being one of the most productive fisheries in the Northwest Atlantic, much remains unknown about the natural reproductive dynamics of American lobsters. Recent work in exploited crustacean populations (crabs and lobsters) suggests that there are circumstances where mature females are unable to achieve their full reproductive potential due to sperm limitation. To examine this possibility...
متن کاملAmerican Lobsters (Homarus Americanus) not Surviving During Air Transport: Evaluation of Microbial Spoilage
Eighteen American lobsters (Homarus americanus), dead during air transport, were analysed in order to evaluate the microbial population of meat, gills and gut: no specific studies have ever been conducted so far on the microbiological quality of American lobsters' meats in terms of spoilage microbiota. The meat samples showed very limited total viable counts, in almost all the cases below the l...
