Implementing measures to avoid significant adverse impacts to vulnerable marine ecosystems (VMEs) requires a specific list of the taxa that are considered vulnerable in the fishery being assessed. New Zealand identified an interim list of taxa to monitor in fishery by-catch in the Ross Sea as part of its benthic fisheries impact assessment. The rationale for including or excluding each taxonomi...

Tuna purse seine fishery is a commercial and industrial fishery in the Iranian waters of Oman Sea. An observer programme was conducted to identify the by-catch composition of the tuna purse seine fishery in the Iranian waters of the Oman Sea. Investigations were carried out on board of purse seiner vessel “named Parsian Shila” between September and October 2015. The by-catch was composed of 17 ...

A common strategy for limiting the total annual catch in a fishery is to restrict entry and season length. We examine the results of this strategy when entry limitation amounts to a limit on capital, but fishing firms can vary an unrestricted input, and thereby use the restricted input more intensively. Under these regulatory constraints, fishing firms will earn rents that depend on the elastic...

This paper investigates the ability of a new hybrid forecasting model based on empirical mode decomposition (EMD), cluster analysis and Autoregressive Integrated Moving Average (ARIMA) model to improve the accuracy of fishery landing forecasting. In the first step, the original fishery landing was decomposed into a finite number of Intrinsic Mode Functions (IMFs) and a residual by EMD. The seco...

The Madison Swanson Marine Protected Area was established to protect gag grouper, Mycteroperca microlepis, spawning aggregations on high relief, deepwater habitat in the Gulf of Mexico. Fishery biologists observed a decline in the proportion of male individuals in the population. The decline led fishery managers to question the reproductive health of the gag grouper population. However, competi...

Non-fishery use of artificial reefs has been given attention in recent years. The primary concern associated with non-fishery artificial reefs is their effects to the surrounding ecosystems. This study examined the infaunal communities around two non-fishery artificial reefs (the sunken vessels YO257 and Sea Tiger) in Mamala Bay, Hawaii. Infaunal community structures at these artificial reefs w...

Recent reports suggest that many well-assessed fisheries in developed countries are moving toward sustainability. We examined whether the same conclusion holds for fisheries lacking formal assessment, which comprise >80% of global catch. We developed a method using species' life-history, catch, and fishery development data to estimate the status of thousands of unassessed fisheries worldwide. W...

Southern bluefin tuna is a highly valuable, severely depleted species, whose abundance and productivity have been difficult to assess with conventional fishery data. Here we use large-scale genotyping to look for parent-offspring pairs among 14,000 tissue samples of juvenile and adult tuna collected from the fisheries, finding 45 pairs in total. Using a modified mark-recapture framework where '...
