Evidence for Magnetoreception in Red Drum (Sciaenops ocellatus), Black Drum (Pogonias cromis), and Sea Catfish (Ariopsis felis)
Over the past few decades, magnetoreception has been discovered in several species of teleost and elasmobranch fishes by employing varied experimental methods including conditioning experiments, observations of alignment with external fields, and experiments with magnetic deterrents. Biogenic magnetite has been confirmed to be an important receptor mechanism in some species, but there is ongoin...
متن کاملA genetic linkage map of red drum, Sciaenops ocellatus.
Second-generation, sex-specific genetic linkage maps were generated for the economically important estuarine-dependent marine fish Sciaenops ocellatus (red drum). The maps were based on F(1) progeny from each of two single-pair mating families. A total of 237 nuclear-encoded microsatellite markers were mapped to 25 linkage groups. The female map contained 226 markers, with a total length of 127...
متن کاملAge, Growth, and Mortality of Black Drum, Pogonias cromis, in the Chesapeake Bay Region
-we used otolith ageing to describe the population dynamics of black drum, Pogonias cromis, collected over a three-year period from the Chesapeake Bay region's commercial and recreational fisheries. Black drum average age, total length, and weight were 26 years, 109.5 cm, and 22.1 kg respectively. The oldest fish was 59 years and fish older than 50 years were present in the catch from 1990 to 1...
متن کاملRadiocarbon From Nuclear Testing Applied to Age Validation of Black Drum, Pogonias cromis
-Radiocarbon < 14C >in the world's oceans increased sharply between 1950 and 1970 as a result of the atmospheric testing of nuclear weapons. Through comparison with the 14C time series reconstructed from atmospheric measurements and marine carbonates, Kalish, in 1993, used the 14C concentration measured in fish otolith cores as a means of confirming the annulus-based age estimates for some Sout...
متن کاملOntogeny of critical swimming speed of wild-caught and laboratory-reared red drum Sciaenops ocellatus larvae
Critical swimming speed (Ucrit) provides a useful estimate of maximum swimming performance for fish larvae that can be used to assess transport and migratory potential. We measured Ucrit of red drum Sciaenops ocellatus larvae through its ontogeny and compared the swimming performance of laboratory-reared larvae to that of wild-caught individuals. Ucrit increased with ontogeny (size), even thoug...
