Yellowfin assessments depend on accurate data on catch and on good indices of abundance that can be used to fit production models. Current catch statistics compiled by ICCAT seem accurate, but historic catches may have been at least partially under-reported. In this paper we investigate the effect that different historic patterns of under-reporting have in the assessment. We do this by fitting ...

Inclusion of catch stabilization mechanisms have been tested in the current HCR and are considered precautionary as they do not increase the probability of SSB< Blim above 0.05. Over the entire time period examined there are no significant differences in catch either with or without the stabilizers. The 50–50 rule may lead to considerably reduced interannual variation (IAV), but can generate hi...

This paper examines the incidence and correlates of linear growth catch up in early childhood among stunted children, using a range of definitions of catch up. Catch-up growth between two and five years of age is defined in both absolute terms (i.e. the centimetre height deficit from the healthy reference population mean is reduced) and relative terms (the height-for-age z-score improved or pas...

the aim of the present research is to survey the effects of environmental and biological factors on rutilus frisii kutum migration in the southwest region of caspian sea. for this purpose sampling was carried out by gillnet cooperatives company in tonekabon city  from november 2013 to april 2014. the total catch per unit effort  was calculated as 220 kg. rutilus frisii kutum  contains 69% of th...

BACKGROUND Analysis of US claims data from April 2010 to June 2011 estimated that 39% of the 13-valent pneumococcal conjugate vaccine (PCV13) catch-up eligible cohort would ever receive the catch-up vaccination; a previous analysis assumed 87%. METHODS This updated figure was applied to a previously published 10-year Markov model while holding all other inputs constant. RESULTS Our model es...

A unique database was created that describes the methods used to allocate shares in nearly every major catch share fishery in the world. Approximately 54% of the major catch share fisheries in the world allocated the Total Allowable Catch (TAC) solely on the basis of historical catch records, 3% used auctions, and 6% used equal sharing rules. The remaining 37% used a combination of methods, inc...

There are differences in perception of the status of fisheries around the world that may partly stem from how data on trends in catches over time have been used. On the basis of catch trends, it has been suggested that about 70% of all stocks are overexploited due to unsustainable harvesting and 30% of all stocks have collapsed to <10% of unfished levels. Catch trends also suggest that over tim...

Catch-up growth, a risk factor for type 2 diabetes, is characterized by hyperinsulinemia and accelerated body fat recovery. Using a rat model of semistarvation-refeeding that exhibits catch-up fat, we previously reported that during refeeding on a low-fat diet, glucose tolerance is normal but insulin-dependent glucose utilization is decreased in skeletal muscle and increased in adipose tissue, ...

Catch-up growth is a risk factor for later obesity, type 2 diabetes, and cardiovascular diseases. We show here that after growth arrest by semistarvation, rats refed the same amount of a low-fat diet as controls show 1) lower energy expenditure due to diminished thermogenesis that favors accelerated fat deposition or catch-up fat and 2) normal glucose tolerance but higher plasma insulin after a...

Traps that use ultraviolet light as an attractant for flies are widely used in urban situations. To determine the differences in trap efficacy from design and lighting, pairs of traps were compared under laboratory conditions. Comparisons were made between traps with open fronts and with traps with restricted open fronts, black light bulbs, and black light blue bulbs, and glue boards with and w...
