Modified handling is often claimed to reduce (sub-)lethal impacts among organisms caught-and-released in fisheries. Improving welfare of discarded fish warrants investigation, when their survival is of both economic and ecological importance. In this study, juvenile yellowfin bream (Acanthopagrus australis) were trawled in an Australian penaeid fishery and then discarded after on-board sorting ...

Elements contained within calcified structures of fish, molluscs, bivalves and corals may provide a means to determine the characteristics of the environment occupied by an organism over time. In order to establish these characteristics it is first important to establish a link between one or more environmental variables and the concentration of elements within such a calcified structure. Black...

Received:1 March, 2014 Accepted: 12 April, 2014 Published: 20 May, 2014 The differentially expressed genes by exposure to environmental pollutants can provide the important information about the reaction mechanisms in the organism as well as adaptation to exterior stresses or environmental changes. Also they can be developed as biomarkers for the detection of environmental stress and exterior s...

Measurements of closely related sets of classical and truss dimensions were analyzed to discriminate species of scorpaenidae including the dark banded rockfish, Sebastes inermis, the black rockfish, S. schlegeli, and gobioninae including the striped shiner, Pungtungia herzi, and the slender shiner, Pseudopungtungia tenuicorpa. The measurements of the dimensions were arc sin square root transfor...
