Abstract Developing Species Distribution Models (SDM) for marine exploited species is a major challenge in fisheries ecology. Classical modelling approaches typically rely on fish research survey data. They benefit from standardized sampling design and controlled catchability, but they usually occur once or twice year may sample relatively small number of spatial locations. Spatial monitoring c...
Live transport of fishes is recognised as a major source stress leading to poor welfare and mortality within the ornamental fish industry. While previous studies have aimed simulate stressors experienced by during in laboratory, there little documented evidence actual conditions under commercial conditions. The aim this study was monitor water quality health (physiology behaviour) through suppl...
BACKGROUND Sea lice infection is the most expensive disease factor for Atlantic salmon sea-cage farming. For triploid salmon to be accepted as a commercial possibility, investigation of susceptibility of triploid salmon to sea lice infection is a fundamental milestone. The susceptibility of diploid and triploid salmon to infection with Lepeophtheirus salmonis was examined in a tank trial in Sco...
Vision based solution of safe navigation for commercial vehicles with fish-eye camera is presented in this paper. This work aims to develop a system which is able to detect persons or objects around commercial vehicles for preventing any accidents. This is achieved by integrating classifier based window searching algorithm and ego-motion based algorithm into the system. The classifier is traine...
The increasingly intense competition between commercial and recreational fishermen for access to fish stocks has focused attention on the economic implications of fishery allocations. Indeed, one can scarcely find a management plan or amendment that does not at least refer to the relative food and sport values of fish and to how expenditures by commercial and recreational fishermen on equipment...
THE LOUSEFISH, Phtheirichthys lineatus (Menzies) , is a slender member of the Echeneidae which is often free-swimming but which also attaches to immotile objects or slow-swimming fishes. It is pantropical, uncommon, and little known biologically. This paper reports on 24 lousefish in the collections of the Bureau of Commercial Fisheries Biological Laboratory in Honolulu. Capture data for these ...
