The surge of research on marine litter is generating important information its inputs, distribution and impacts, but data the nature origin remain scattered. Here, we harmonize worldwide litter-type inventories across seven major aquatic environments find that a set plastic items from take-out food beverages largely dominates global litter, followed by those resulting fishing activities. Compos...

Abstract Information on movements and connectivity among populations of animals is important for the delineation units to conserve, so that demographic parameters, such as abundance, fecundity mortality, can be placed in an appropriate population conservation context. Common bottlenose dolphins ( Tursiops truncatus ) are often considered relatively ‘resident’ demonstrating strong site fidelity ...

The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...

This article uses a longitudinal survey (1999–2005) of commercial stakeholder organizations (CSOs) to assess the development, strengths and weaknesses of New Zealand’s fisheries co-management over its first six years. After presenting the current characteristics and activities of CSOs, the institutional analysis and development (IAD) Framework is used to examine the regime. Results show a patte...

We are examining how populations of euphausiids maintain high concentrations in coastal regions of the California Current despite the highly advective field. We are testing the hypothesis that mesoscale eddies and coastal counter currents create retention cells, where growth and reproduction are rapid and mortality is reduced. The immediate objective is to produce a data set on the biomass, pop...

We develop an economic model for a multi-species fishery that incorporates the spatial distribution of effort and fish stocks. Catchability coefficients and initial stocks are estimated from catch and effort data for each specific location. Vessels are allocated over space and time to locations of maximum profit which decline with harvest because of stock externalities. A supply function for la...

Small-eyed ray (Raja microocellata) is found on the inner continental shelf in the east Atlantic from the south-western coasts of the British Isles to northern Morocco (Stehmann and Bürkel, 1984). It is locally abundant in the Bristol Channel and parts of the English Channel (Ellis et al., 2005). It is an inshore demersal species, inhabiting the inner continental shelf waters down to a depth of...

Five species of apseudomorph tanaidaceans were distinguished in recent samples from inshore waters off Brunei. Two of these, Phoxokalliapseudes gobinae and Mendamanus ailurostoma, were known only from Brunei waters, while Pagurapseudopsis gracilipes was known before only from Vietnam waters. The opportunity is taken to describe the female cheliped of P. spinipes, highlighting the previously unk...

Astyanax cocibolca, a small filter-feeding species is a new characid species endemic to Lake Nicaragua. It is distinguished from the syntopic Astyanax aeneus by its high gill raker count, slender body, upturned snout, long maxillary bones, conical outer premaxillary teeth, lower number of scales above lateral line, more intense black lateral band, smaller size, and trophic niche partitioning. A...
