We explore a fishery targeting the mature part of a stock, while bycatching the immature part. Both targeted catch and bycatch may have positive market values. Cost of effort is supposed to be a function of the selection properties of the fishing gears. Mature fish is assumed to cannibalise on the immature part of the stock. A bioeconomic model of the problem is set up and it is shown that the model ...

Benthic marine invertebrates collected from sub-Arctic regions of northern Norway, were found to be a promising source of novel bioactive compounds against human and fish pathogenic bacteria and fungi. Lyophilized material from seven species of ascidians, six sponges and one soft alcyonid coral were extracted with 60% acidified acetonitrile (ACN). After separation into an ACN-rich phase (ACN extract) ...

This study investigates the level and determinants of technical efficiency for a sample of gilnnet fishing vessels operating in Da Nang in 2009 by using a stochastic production frontier, which involved the simultaneous estimation of a translog stochastic frontier model and a model for vessel-specific technical inefficiencies. Furthermore, the other important determinants of this fleet were also ...
