This paper describes a methodology that combines meta-population theory and stock assessment models to gain insights about spatial heterogeneity of the meta-population in an operational time frame. The methodology was tested with stochastic simulations for different degrees of connectivity between sub-populations and applied to two case studies, North Sea cod (Gadus morua) and Northeast Atlanti...
Bait usage in the KwaZulu-Natal recreational and commercial linefishery was assessed using historic fisher-derived data and current sales records of bait providers. Total bait usage in two of the three linefishery components in KZN was estimated to range from 928 3,400 tonnes per year. A total of 39 different bait types were identified to have been used in the KZN linefishery, and sardines (Sar...
Sind sardine Sardinella sindensis (Day, 1878) is the most important ecological and commercial surface resources in Persian Gulf and Oman sea. This study was carried to study some population dynamics parameters of Sind sardine in Coastal waters of Jask Province during January 2011 to December 2012. A totall 2887 specimens were collected from commercial fishing Purse seiners, monthly. Biometric p...
BACKGROUND Krill oil, rich in n-3 (omega-3) polyunsaturated fatty acids (PUFAs) incorporated in phosphatidylcholine, has been reported to have many effects on physiological function. However, there are few studies using psychophysiological methods published that describe the effects of krill oil on brain function. We investigated the influence of ingestion of krill oil on cognitive function in ...
The influence of dietary lipids on the liver microsomal mixed function oxidase system and on pentobarbital-induced sleeping time was studied in rats. Giving diets containing (g/kg) 150 olive oil, 150 lard or 150 soya-bean oil for 21 d (Expt 1) increased the cytochrome P-450 content in the order: olive oil less than lard less than soya-bean oil. When diets containing (g/kg) 150 lard, 150 soya-be...
To achieve sustainable fisheries implies that resources’ management is carried out in accordance with biologically and ecologically relevant processes. In this context, to infer the boundaries of genetic stocks along their distribution crucial avoid depletion diversity induced by fishing pressure. Despite its remarkable ecological role commercial interest, there are still many uncertainties abo...
The influence of sea-cage aquaculture on wildfish assemblages has received little attention outside of Europe. Sea-cage aquaculture of finfish is a major focus in South Australia, and while the main species farmed is southern bluefin tuna (Thunnus maccoyii), there is also an important yellowtail kingfish (Seriola lalandi) industry. Yellowtail kingfish aquaculture did not appear to have any loca...
