Maximising the survival of bycatch discarded from commercial estuarine fishing gears in NSW
The mortalities and contributing parameters were estimated for key species discarded during commercial gillnetting (80-mm mesh) targeting dusky flathead Platycephalus fuscus in a southeastern Australian estuary. Bycatches (1470 individuals from 16 species over 11 deployments) were assessed for their immediate mortalities onboard the gillnetter, before subsamples (570 individuals from 11 species...
متن کاملPlatycephalus orbitalis, a new species of flathead (Teleostei: Platycephalidae) collected from western Australia
A new plataycephalid, Platycephalus orbitalis, is described on the basis of specimens collected in the Indian Ocean off the coast of Western Australia at depths of 50–144 m. The new species had been mistakenly identified as P. marmoratus, which is now known to be restricted to eastern Australia. Several morphological characters (e.g, 65–68 pored scales in lateral line, snout and interorbit nake...
متن کاملTaxonomic revision of the flathead fish genus Platycephalus Bloch, 1785 (Teleostei: Platycephalidae) from Australia, with description of a new species.
The taxonomy of the fish genus Platycephalus Bloch, 1785 from Australia is revised following examination of all extant primary types of Australian species, including those previously synonymized. The following 16 Australian species, including a single new species, are recognized in this study: Platycephalus angustus Steindachner, 1866, Platycephalus aurimaculatus Knapp, 1987, Platycephalus bass...
متن کاملDevelopment of the skeleton and feathers of dusky parrots (Pionus fuscus) in relation to their behaviour.
A clutch of five dusky parrots (Pionus fuscus) was observed from hatching to fully grown. They were examined radiographically from 16 to 45 days of age, a few days before the cessation of bone growth, and the development of their feathers and their behaviour were also studied. It was observed that when growing birds were removed from the nest and placed singly on a flat surface they would stand...
متن کاملConservation genetics of extremely isolated urban populations of the northern dusky salamander (Desmognathus fuscus) in New York City
Urbanization is a major cause of amphibian decline. Stream-dwelling plethodontid salamanders are particularly susceptible to urbanization due to declining water quality and hydrological changes, but few studies have examined these taxa in cities. The northern dusky salamander (Desmognathus fuscus) was once common in the New York City metropolitan area, but has substantially declined throughout ...
