Long-term Trends in Demersal Fishery Resources
A brief review is presented of the structure of the Ghanaian fishing fleet, and of the changes they induced on their resource base since the 1960s. These change consist of a reduction of the biomass of longer lived fishes, particularly in shallower waters, and in conjunction with environmental fluctuation, the creation of opportunities for invasive species of fish (triggerfish Balistes caroline...
متن کاملTrawl Selectivity in the Barents Sea Demersal Fishery
This chapter provides a general overview of the Barents Sea demersal trawl fishery. First, it reviews historical catch levels and current biomass status of four commercially important demersal species (cod, haddock, Greenland halibut, and redfish) and includes an overview of their management plan that has been carried out by the Joint Norwegian–Russian commission. Then, it presents the evolutio...
متن کاملMulti-Tracking of Moving Objects with Unreliable Sensors for Mobile Robotic Platforms
This work presents a method for tracking multiple moving objects from noisy and unreliable data taken by a mobile robotic platform. We develop a multihypothesis tracking algorithm based on Kalman filtering. The approach is implemented on a four-legged AIBO robot and tested in the context of multiple-balls tracking in the RoboCup domain, with features extracted from the vision module.
متن کاملA Survey of the Demersal Fishery in the Kigoma Area
Lake Tanganyika is the largest of the African rift lakes and the second deepest lake in the world (Coulter, 1991). It provides many critical services to communities in the four riparian countries of Tanzania, Zambia, D. R. Congo, and Burundi, and serves as an important source of protein through its vibrant fishery (Coulter, 1991). This fishery can be divided into two general categories based on...
متن کاملComparing Acoustic Tag Attachments Designed for Mobile Tracking of Hatchling Sea Turtles
The poorly understood movements of sea turtles during the “lost years” of their early life history have been characterized as a “passive drifter” stage. Biologging technology allows us to study patterns of dispersal, but the small body size of young life stages requires particular consideration that such tagging does not significantly impede animal movements. We tested the effect of instrument ...
