As climate change accelerates and fisheries management continues to evolve, California's commercial are changing. To improve the understanding of recent California dynamics, we compiled analyzed landings receipts characterize temporal spatial variation in landing value key groups within exclusive economic zone across state from 2005 2019. We found that continue a shift first observed 1980s high...

the size composition, growth pattern, sex ratio and feeding habits of the blue swimming crab, portunus segnis from persian gulf in south of iran, was studied. sampling was performed by trawl net during a one- year period (july 2011 to may 2012) as processed 864 crabs was collection. the crabs carapace width ranged were from 7.5-17.5 cm for males and 7.0-16.5 cm for females. the crab carapace le...

Many introduced marine organisms are ecological and economic pests. Nevertheless, no management approach is available to mitigate their impacts. Now, a theoretical perspective borrows principles from classical biological control, as widely applied to terrestrial and fresh water systems, to control the abundance of introduced marine pests. A banner example of a marine pest is the European green ...

Abstract The increase in fuel prices will gradually have an impact on the capture fisheries sub-sector, especially fishermen. Sail technology is alternative that can be used to save oil, although it realized this cannot completely replace diesel motor commonly fishing operations. This study explain application opportunities of sail vessels for blue swimming crab (Portunus pelagicus) deep waters...

Context The spanner crab (Ranina ranina) stock of eastern Australia is distributed across two state jurisdictions and, as a non-migratory species with pelagic larval phase, connectivity within this likely to occur by dispersal, driven ocean currents. Aims To understand and patterns supply in the Australian stock. Methods Lagrangian particle tracking methods were used simulate transport around k...

We present the results of deep, high-resolution, multi-band optical observations of the field of the young (∼ 5, 000 yrs) 16 ms X-ray pulsar PSR J0537−6910 performed with the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope (HST). Although a few new potential counterparts have been detected within or close to the revised Chandra X-ray error circle (≃ 1′′) of the pulsar, only ...

During its life, BeppoSAX observed several isolated pulsars, giving important contributions to the knowledge of the phenomenology and properties of the X-ray emission from this class of sources. In this paper I review the spectral and timing results obtained from BeppoSAX observations. In particular, results on three Crab-like (Crab, PSR B1509-58 and PSR B0540-69) and 3 millisecond pulsars (PSR...
