Linkage Disequilibrium Estimation of Effective Population Size with Immigrants from Divergent Populations: A Case Study on Spanish Mackerel (Scomberomorus commerson)
Estimates of genetic effective population size (Ne) using molecular markers are a potentially useful tool for the management of endangered through to commercial species. However, pitfalls are predicted when the effective size is large because estimates require large numbers of samples from wild populations for statistical validity. Our simulations showed that linkage disequilibrium estimates of...
متن کاملPopulation dynamics of the Spanish mackerel (Scomberomorus commerson) in coastal waters of Oman Sea
Length composition data of narrow-barred Spanish mackerel, Scomberomorus commerson (Lacepede 1800), landed between April 2002 to March 2004, were monthly used to estimate the growth, mortality and exploitation parameters of the stock. Maximum fork length and weight were 170 cm and 38 kg, respectively. Nonlinear least square fitting provided a complete set of von Bertalanffy growth estimates: L&...

متن کاملThe effect of Hanging Ratio Factor on the catch amount of multifilament gill nets in coastal waters of Bushehr province, Persian Gulf
The aim of this study was to comparing the effect of different hanging ratios (E=0.5 and 0.6) of drift gillnets on catch rates, length composition and Catch per Unit Effort (CPUE) in Bushehr coastal waters between late September 2010 to late March 2011. The length frequency of Spanish Makerels did not differ significantly between gillnets with 0.5 and 0.6 hanging ratios (P>0.05). A total of 558...
متن کاملFeeding performance of king Mackerel, Scomberomorus cavalla.
Feeding performance is an organism's ability to capture and handle prey. Although bite force is a commonly used metric of feeding performance, other factors such as bite pressure and strike speed are also likely to affect prey capture. Therefore, this study investigated static bite force, dynamic speeds, and predator and prey forces resulting from ram strikes, as well as bite pressure of the ki...
