As part of monitoring, control and surveillance marine fisheries, a logbook monitoring vessel system (VMS) were introduced for multi-day fishing. The present study investigates the possibility using VMS data to validate records fishing locations vessels. from 1,424 multiday vessels fitted with VMS, which was operated May 2017 April 2018. During period, there 17,626 trips 66,717 occasions. In tr...

This paper examines development of tourism in Korean fishing communities, and illustrates the ways in which the responses of the state and the fishing village cooperative to tourism have advanced the privatization of commonly held local fishing grounds and of cooperative businesses. The financial assistance from the state and some privatization of common fishing grounds by the cooperative preci...

The effects of climate and fishing on marine ecosystems have usually been studied separately, but their interactions make ecosystem dynamics difficult to understand and predict. Of particular interest to management, the potential synergism or antagonism between fishing pressure and climate forcing is analysed in this paper, using an end-to-end ecosystem model of the southern Benguela ecosystem,...

The Pacific coast of Colombia has some of the most extensive mangrove forests in South America. As an isolated region and one of the country’s poorest, coastal communities rely on fishing as a main source of animal protein and income. In an attempt to reverse declining trends of fisheries resources, in 2008, an Exclusive Zone of Artisanal Fishing closed to industrial fishing, was established by...

To understand how fisheries affect parasites, we conducted a meta-analysis of studies that contrasted parasite assemblages in fished and unfished areas. Parasite diversity was lower in hosts from fished areas. Larger hosts had a greater abundance of parasites, suggesting that fishing might reduce the abundance of parasites by selectively removing the largest, most heavily parasitized individual...

There is great need to identify simple yet reliable indicators of fishing effects within the multi-species, multi-gear, data-poor fisheries of the Caribbean. Here, we investigate links between fishing pressure and three simple fish metrics, i.e. average fish weight (an estimate of average individual fish size), fish density and fish biomass, derived from (1) the parrotfish family, a ubiquitous ...

Marine debris is a growing global marine environmental issue. It causes negative and serious impacts on marine ecosystem, tourism, navigation safety, and fisheries. Derelict fishing gears (DFGs) have been considered as one of the major sources of marine debris in the Korean seas. The Korean government has implemented many policy measures to control DFGs since late 1990s. We compared three repre...

In recent years, global demands for safe and sustainable ships led to dramatic changes in maritime industry. Digitalization is expected play important part the future. This supported by analysis of autonomous market which shows that digitalization large ship types such as tankers container well on track. Although date designs High Speed Craft (HSC) have been developed, there are only a few stud...
