Life cycle assessment of aquaculture systems—a review of methodologies
PURPOSE As capture fishery production has reached its limits and global demand for aquatic products is still increasing, aquaculture has become the world's fastest growing animal production sector. In attempts to evaluate the environmental consequences of this rapid expansion, life cycle assessment (LCA) has become a frequently used method. The present review of current peer-reviewed literature...
متن کاملLocomotion in scombrid fishes: morphology and kinematics of the finlets of the chub mackerel Scomber japonicus.
Finlets are small non-retractable fins located on the dorsal and ventral margins of the body between the second dorsal and anal fins and the tail of scombrid fishes. The morphology of the finlets, and finlet kinematics during swimming in a flow tank at speeds of 0.8-3. 0 fork lengths s(-1), were examined in the chub mackerel Scomber japonicus. Functionally, S. japonicus has five dorsal and anal...
متن کاملWestern Regional Aquaculture Center
Algae are the population of microscopic single and multiple-celled aquatic plants that live in water. While most individual algal cells can only be viewed using an instrument such as a microscope, algal blooms give color to the pond water. When populations of algal cells multiply, thereby clouding or giving color to a pond, it is called an algal bloom. Another term used to describe algae is phy...
متن کاملSteroidogenic and maturation-inducing potency of native gonadotropic hormones in female chub mackerel, Scomber japonicus
BACKGROUND The gonadotropins (GtHs), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are produced in the pituitary gland and regulates gametogenesis through production of gonadal steroids. However, respective roles of two GtHs in the teleosts are still incompletely characterized due to technical difficulties in the purification of native GtHs. METHODS Native FSH and LH were pu...
متن کاملThree-dimensional analysis of finlet kinematics in the chub mackerel (Scomber japonicus).
Finlets, which are small non-retractable fins located on the body margins between the second dorsal and anal fins and the caudal fin of scombrid fishes, have been hypothesized to improve swimming performance. The kinematics of three posterior finlets of the chub mackerel, Scomber japonicus, were examined using three-dimensional measurement techniques to test hypotheses on finlet rigidity and fu...
