Social Learning of Prey Location in Hatchery-Reared Atlantic Salmon
Naïve, hatchery-reared Atlantic salmon Salmo salar parr were paired with demonstrators that had been pre-trained to accept live prey from the surface or from the benthos. After 6 days of observing demonstrators through a clear perspex partition the naïve fish’s benthic foraging skills were tested. The results revealed that hatchery-reared Atlantic salmon can be taught to target benthic prey ite...
متن کاملFeeding performance of juvenile hatchery-reared spotted seatrout Cynoscion nebulosus.
The feeding performance of individual hatchery-reared (HR) and wild juvenile spotted seatrout Cynoscion nebulosus was compared across a series of six 1·5 h feeding exposures over a 3 day period in a controlled experiment. The predation cycle served as a context for discerning feeding performance elements. The experimental design facilitated assessments of the effects of experience, motivation d...
متن کاملUnexplained Mortalities of Hatchery-reared, Juvenile Oysters, Crassostrea Virginica (gmelin)
Survival, growth and pathology of juvenile oysters, Crassostrea virginica, in off-bottom culture at Oyster Bay and Fishers Island, New York, were monitored during the summer of 1991 to document and help explain the episodic mass mortalities of cultured seed oysters that have occurred in the northeastern USA over the past several years. At Oyster Bay, where the more detailed study was conducted,...
متن کاملBALB/c Mice Immunity to Hydatidosis Induced by In-vitro Reared Echinococcus granulosus Adult Worm Antigens
Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...
متن کاملDescriptions of diplostomid metacercariae (Digenea: Diplostomidae) from freshwater fishes in the Tshwane area.
The metacercarial (larval) stages of diplostomid digeneans are known to inhabit freshwater fish, causing tissue damage in the process. Due to their widespread diversity, little is known about their life cycle. The classification of these parasitic stages to the species level using only the morphology is very challenging due to the lack of genitalia; they are regarded to be the most important st...
