Glass eels, the young life stage of endangered European eel entering continental waters, are exploited for human consumption (direct, or on-grown) and restocking. Restocking is considered as a potential contribution to conservation stock. For this, mortality glass eels during capture should be low. We studied handling obtained by commercial push net fisheries in different rivers France 2019 202...

The application of agent methodologies in process monitoring and control is a relatively novel approach, particularly suitable for distributed and dislocated systems. As for marine reservers, access monitoring is aimed at avoiding intrusions of unauthorized boats – also considering that, typically, marine reserves are located in areas not easily accessible. Typical solutions consist of using ra...

Setting up a marine reserve involves access monitoring, with the goal of avoiding intrusions of not authorized boats – also considering that, typically, marine reserves are located in areas not easily accessible. Nowadays, intrusion detection in marine reserves is carried out by using radar systems or suitable cameras activated by movement sensors. In this paper, we present a multiagent system ...

DURING 8 DAYS in early August and October, 1968, the members of an expedition from the University of Hawaii examined the distribution and abundance of sea urchins in two bays along the Kona (leeward) Coast of the Island of Hawaii (Fig. 1) : Kealakekua Bay (19 0 28' N; 155 0 55' W) and Honaunau Bay (19 0 25' N ; 155 0 55' W). The major sampling effort was expended in Kealakekua, the larger of th...

The goal of this paper is to strengthen the supervision fishing behavior in East China Sea and effectively ensure sustainable development fishery resources. Based on AIS data, analyzes three types boats (purse seine operation, gill net operation trawl operation) uses cubic spline interpolation algorithm optimize ship trajectory construct high-dimensional features. It proposes a new coding metho...

Black carbon (BC) emitted from diesel fuel combustion contributes significantly to particulate matter emissions that impact air quality and human health. Off-road sources of BC are increasingly important as on-road vehicles continue decrease. This study characterizes harbor craft activity, including tugboats, passenger boats, fishing vessels. Vessel traffic data suggest the Southern California ...

Mini purse seine boats in Rembang are divided into two sizes. The first one, namely mini seines measuring 10 - 20 Goss Tonnage (GT) (short trips) with a fishing operation duration of 3 7 days. second one is 21 30 GT (long dominant catch on this round scad, which used cooling mechanism ice blocks and bulking systems. This research evaluates the quality scad caught by (based Indonesian National S...

Several traditional fishing boats in Sendang Biru, Malang Regency are of the sekoci type using an inboard engine drive system with position propeller shaft installed at angle to ship's base line. Based on theory can reduce performance ship propulsion up (2-3)%. In this research, we analyzed how much was lost/decreased lifeboat above. The method use is Free Running Model Test by making a model b...
