Gill net selectivity for European hake Merluccius merluccius from southern Portugal: implications for fishery management
A study of European hake Merluccius merluccius gill net selectivity was undertaken off the Algarve (Southern Portugal), between 1999 and 2001. Four nominal mesh sizes (70, 80, 90 and 100 mm) were used in fishing trials and the ‘share each length class catch total’ (SELECT) method was used to fit gill net selectivity curves. Hake were caught in the same size range by all mesh sizes, between 17 a...
متن کاملImpact of egg production and stock structure on MSY reference points and its management implications for southern hake (Merluccius merluccius)
Spawning stock biomass (SSB) is one of the most common measures of stock status. However recent research on reproductive potential has shown that alternative variables may be an improvement over SSB. In the case of European hake (Merluccius merluccius), it is known that large individuals produce more eggs by unit of body weight, and their quality is better than those of small individuals. Under...
متن کاملProtein denaturation in frozen stored hake (Merluccius merluccius L
Protein solubility of whole and minced muscle of hake (Merluccius merluccius L.) was evaluated at different temperatures of storage: -5°, -12° and -20°C. Proteins soluble in 1% NaCl did not show any change at any of the temperatures of storage, while the 5% NaCl-soluble proteins decreased significantly when whole hake was stored at -5° and 12°C (p < 0.01). A correlation was found between the de...
متن کاملSome characteristics of sperm motility in European hake (Merluccius merluccius, L., 1758)
The objective of this paper is to characterize some of the sperm motility parameters in European hake (Merluccius merluccius), which is considered to be a species with aquaculture potential. The total ATP, ADP and AMP concentrations were determined using high-performance liquid chromatography on hake sperm samples collected during the winter-early spring in the Bay of Biscay (France) (n = 22) a...
متن کاملInfectious pancreatic necrosis virus isolated from hake, Merluccius merluccius, from Scotland
Wild marine fish caught from a sea loch on the West Coast of Scotland were tested for infectious pancreatic necrosis virus (IPNV). One pool of 10 hake was found to be IPNV positive from 449 fish tested. This is believed to be the first isolation of IPNV made from hake caught in northern European waters. This was the only positive pool obtained from the study, illustrating a low prevalence of IP...
