Behavioral responses to encounter of fishing boats in wandering albatrosses
Animals are attracted to human food subsidies worldwide. The behavioral response of individuals to these resources is rarely described in detail, beyond chances of encounters. Seabirds for instance scavenge in large numbers at fishing boats, triggering crucial conservation issues, but how the response to boats varies across encounters is poorly known. Here we examine the behavioral response of ...
متن کاملTwo Heat Pipe Type High Efficient Adsorption Icemakers for Fishing Boats
The adsorption performances of compound adsorbent (the mixing of activated carbon and CaCl2 by proper technology)-ammonia are studied, which shows the obviously improvement for long term stable operation of adsorption/desorption, and also the large adsorption cooling density. A multifunction heat pipe for heat transfer design in adsorber is invented to use waste heat for heating and sea water f...
متن کاملOverturning conclusions of Lévy flight movement patterns by fishing boats and foraging animals.
A surprisingly diverse variety of foragers have previously been concluded to exhibit movement patterns known as Lévy flights, a special type of random walk. These foragers range in size from microzooplankton in experiments to fishermen in the Pacific Ocean and the North Sea. The Lévy flight conclusion implies that all the foragers have similar scale-free movement patterns that can be described ...
متن کاملOptimum fishing strategies for Isostichopusfuscus (Echinodermata: Holothuroidea) in the Gulf Of California, Mexico.
The Isostichopus fuscus fishery in Mexico was heavily exploited until 1994, when it was closed due to overfishing. However, no information existed on the status of the populations. The fishery was evaluated through an age structured simulation model, and according to our analysis of the stock, the fishery can be feasible and sustainable as long as fishing mortality and age of first catch are op...
متن کاملOptimum Fisheries Management under Climate Variability: Evidence from Artisanal Marine Fishing in Ghana
In most developing coastal countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could impact the environmental carrying capacity of the fish stock. This study investigates the effect of ...
