The West Coast Rock Lobster Managed Fishery (WCRLMF) moved from input to output controls in 2010. This change affected the relativity of fishery-based data sources (e.g., catch rates and landed size composition), making assessment fishery problematic. A novel examination stock dynamics was required ensure robustness associated management arrangements. study derived estimates current biomass lev...

Abstract In the Northern Alboran Sea, artisanal small-scale fisheries using trammel nets suffer economic losses, and local fishermen see their way-of-life endangered, due to interactions with wildlife species such as alien dolphins. On one hand, seaweed Rugulopteryx okamurae , which was first recorded in Sea 2015, has undergone an intensive expansion sub-region, monopolizing available seabed, c...

Though mesopelagic fish respond to natural light (e.g., diurnal vertical migration), few studies have looked at how they artificial and if lights could be used in commercial operations improve catchability of fish. Here we present a preliminary study on organisms blue green spotlights, as well red white diffuse Masfjorden (Norway; max depth 480 m). The response each the three sound scattering l...

The optical acceleration cancelation (OAC) strategy, based on Chapman's (1968) analysis of the outfielder problem, has been the dominant account for the control of running to intercept fly balls approaching head on. According to the OAC strategy, outfielders will arrive at the interception location just in time to catch the ball when they keep optical acceleration zero. However, the affordance ...

Ferox Trout are large, long-lived piscivorous Brown Trout (Salmo trutta). Due to their exceptionally large size, Ferox Trout are highly sought after by anglers while their life-history strategy, which includes delayed maturation, multiphasic growth and extended longevity, is of interest to ecological and evolutionary modelers. However, despite their recreational and theoretical importance, litt...

Data on the depth and temperature preferences of bigeye tuna (Thunnus obesus) derived from archival tags were integrated with data on the spatial and temporal distribution of catches from an eastern Australian longline fishery to investigate the relationship between bigeye tuna behaviour and the fishery. Tagged individuals demonstrated variability in depth and water temperature preferences on d...

Abstract Catostomidae (catostomids) are suckers of the order Cypriniformes, and majority species native to North America; however, in this group understudied rarely managed. The popularity bowfishing gigging for United States has increased concerns related overfishing. Little information exists about relative gear effectiveness sampling catostomids. We sought evaluate boat electrofishing Black ...
