Abstract:

In general, the fishing fleets operating in Maluku waters are consisted of monohull and trimaran vessels with outriggers managed by local entrepreneurs. Monohull fishing vessels have limited deck space and low transverse stability, whereas trimaran fishing vessels have more deck space and greater transverse stability than monohull fishing vessels, but space is still limited due to their outrigger shape. This study aimed to analyze the development of the trimaran fishing vessel in terms of energy requirements, safety and comfort of the crew during fishing operations. At the beginning of this re

Abstract:

Fishing vessel is one of an important thing among a fishing unit. All fishing activities are carried out on fishing vessel. In Indonesia, the shape and size of fishing vessels are vary, depending on the habits of the fishers and the area where the fishing vessels are built and operated. In West Aceh Regency, there are fishing vessels with various sizes. This study aims to identify the shape of fishing vessels measuring less than 10 gross tonnages (GT) at the Fish Landing Base (PPI) Ujong Baroh, West Aceh Regency.

Abstract:

Monitoring and understanding the behavior of fishing vessels are important in facilitating effective management, preventing illegal fishing, informing fishing grounds and evaluating effects of harvests on fishery resources. In recent decades, a large quantity of real-time data of fishing vessels have become available with the development of vessel-tracking systems, making it possible to study the behavior of fishing vessels in high spatial and temporal resolutions. To effectively and efficiently deal with the large amount of data, algorithms from artificial intelligence (AI) are increasingly a

A model for optimal planning of fishing activities has been proposed. It includes the formation of a biological component (a set of fishing objects considered taking into account their distribution over fishing zones) and a technological component (a set of fishing vessels and fishing technologies). On the basis of these two components, the technological chain "field object – production vessel – production technology" is formed. For each type of fishing vessel, it is permissible to use a certain type (or several types) of fishing technologies that are directly related to fishing objects, their

Abstract:

A catch unloading is a fishing vessel activity carried out regularly at the port. The high frequency of unloading activities leads to a long queue which requires fishing vessels to wait in significant time for their unloading turn. One of the fishing ports with a significant waiting time is Karangsong Port, where the unloading queue can reach three weeks. To reduce the waiting time, there is a need to identify the utilization level of unloading facilities and queue patterns, as well as calculate unloading time and its influencing factors at Karangsong fishing port.

Thus, they are not subject to the International Maritime Organization (IMO) maneuverability standards, affecting research on maneuverability. However, upon referencing the statistics of marine accidents related to vessel maneuvering, the number of marine accidents caused by fishing vessels is 3 to 5 times higher than that of merchant ships. Therefore, systematic and consistent research on the maneuverability characteristics of fishing vessels is surely required. In particular, a fishing vessel frequently enters

Abstract Danish fishing vessels can be characterized by their diversity of fishing practice in terms of fishing gear and target species, and by their operational flexibility in respect of these fishing practices throughout the year. We describe the temporal fluctuations in this flexibility by following the activity of individual fishing vessels between 1989 and 2001. Initially, a typology of fisheries (classification of fishing trips) and vessel groups (classification of fishing vessels) was established through multivariate analyses of catch and effort data for 1999.

The management plan is still challenging to implement because there is no information about the vessel storage volume. In addition, small fishing vessel fishers still store their catch in boxes made of fibre-reinforced plastic (FRP). That box is often placed on the deck floor, causing decreased vessel stability. The size of the available storage volume on the vessel must be ideal, so it needs to be compared with the cubic number. This research aims to dete

Abstract:

Recent technological developments facilitate the collection of location data from fishing vessels at an increasing rate. The development of low-cost electronic systems allows tracking of small-scale fishing vessels, a sector of fishing fleets typically characterized by many, relatively small vessels. The imminent production of large spatial datasets for this previously data-poor sector creates a challenge in terms of data analysis. Several methods have been used to infer the spatial distribution of fishing activities from positional data. Here, we compare five approaches using either vessel sp

Increasing the efficiency of tapping the aquatic biological resources by fishing vessels directly depends on the improvement of production and technological activities in the unpredictable field conditions. Like any production process, the production and technological activity of fishing vessels is associated with the occurrence of costs at all stages (phases) of the production process, the aggregate and structure of which depends on the fishing technological system of the fishing vessel. The stages of the production process form the main material flow, ensuring its end-to-end promotion. Its e

Abstract This paper aims to examine how to protect of artisanal fishermen fishing ground and the policies that protect them. Small-scale fisher fishing grounds has to have a special attention due to their limitation. They are using very simple fishing gear, so they can’t sail far away from the coastal waters. The Fishing law give a specific attention for this matter, by limiting fishermen with 5 gross tonnage (GT) are only able to conduct their activities within the coastal waters.

The vessel that have heavier empty weights will cause poor motion when operating and reduced capacity to accommodate the vessel.

Abstract:

A microcomputer-based program has been developed at the University of British Columbia to help fisherman and naval architects estimate fishing vessel fuel consumption. The program allows users to calculate the fuel consumption for a given fishing trip scenario. The program can then be used to calculate the return on investment of fuel saving improvements made to the vessel such as: Kort nozzle, two speed gearbox, variable-pitch propeller, and new propeller design. The program can be used for the design of small vessels such as tugs and supply vessels.

In general, fishing fleets operating in Maluku waters and managed by local entrepreneurs consist of monohull and trimaran fishing vessels with outriggers. Monohull fishing vessels have limited deck space and poor transverse stability, while trimaran-type vessels have better deck space and transverse stability than monohull vessels, but because they are still in the form of outriggers, the space is limited. This study aims to examine the development of the trimaran fishing vessel in terms of energy requirements, safety, and comfort of the crew during fishing operations. The initial stage of thi

Croatia has a fishing fleet of 7559 vessels. Of these, small-scale coastal fishing boats, less than 12 meters in length, makes up 95,7% of the fleet. However, the largest percentage of catches, more than 94%, is made by purse-seiners that are representing only 3% of total fishing vessels. These vessels target small pelagic fish, predominately sardine and anchovy.

Abstract:

Abstract Minimizing fishing-induced mortality on bycatch and endangered, threatened or protected species is a necessity for fisheries managers. Estimating individual vessel bycatch rates by dividing the amount of bycatch by effort (nominal rate) can be biased, as it does not consider effort heterogeneity within the fleet and ignores prior knowledge of fleet bycatch rates. We develop an empirical Bayesian approach for estimating individual vessel and fleet bycatch rates that: (i) considers effort heterogeneity among vessels and; (ii) pools data from similar vessels for more accurate estimation.
