Biochemical indicators of muscle growth in the snow crab Chionoecetes opilio (O. Fabricius).
This study examined the relationships between muscle growth rate, the activity of metabolic enzymes and the RNA:DNA ratio, in adult snow crabs Chionoecetes opilio. After moulting, crabs were assigned to three feeding rations to attain a range of tissue growth rates. Muscle growth rate, estimated by the variation in dry tissue content per ml of merus of the first walking leg, was positively corr...
متن کاملChanges in muscle of postmoult snow crabs Chionoecetes opilio ( O . Fabricius ) fed different
Somatic growth, muscle cell condition and metabolism, and gonadal production have been 21 21 studied in male snow crabs Chionoecetes opilio fed 0, 0.4 and 2 g ? animal ? day and sampled 5, 25, and 60 days after the terminal moult. Twenty-five days after moulting, muscle growth rate was low in crabs fed a high ration and negative in the other groups, and no gonadal production took place. This su...
متن کاملPathology of Hematodinium infections in snow crabs (Chionoecetes opilio) from Newfoundland, Canada.
Bitter crab disease (BCD) of snow crabs, Chionoecetes opilio, is caused by a parasitic dinoflagellate, Hematodinium sp. The disease has shown an alarming increase in prevalence in the commercial fishery in eastern and northeastern areas of Newfoundland and Labrador since it was first recorded there in the early 1990s. We documented histopathological alterations to the tissues in snow crabs with...
متن کاملMonofilament gill net and trammel net selectivity for the silver crucian carp (Carassius gibelio Bloch, 1782) in the Eğirdir Lake, Isparta-Turkey
The aim of this study was to determine the selectivity of monofilament gillnets with different mesh size for silver crucian carp in Eğirdir Lake. In this study, it was investigated that the selectivity of monofilament gillnets with nominal mesh size (stretched) with 32, 40, 50, 60, 70, 80, 90 mm and trammel nets with 100, 110, 120, 130, 140, 150 mm for catching of silver crucian carp. Fieldwork...
متن کاملAntibiotic Resistance of Bacteria Isolated from the Internal Organs of Edible Snow Crabs
Antibiotic resistance and microbiota within edible snow crabs are important for the Chionoecetes (snow crab) fishing industry. We investigated these parameters using culture methods and antibiotic susceptibility tests with six internal organs from three species of Chionoecetes. Each sample revealed many unexpected microbial species within Chionoecetes internal organs. On the basis of 16S rRNA s...
