1. Introduction. Many pelagic species, including some tunas, exhibit associative behavior underneath floating objects (e.g. logs, seaweed or palm fronds) on the ocean surface (Castro et al., 2002; Hall, 1998).Since the 1980s, artificial fish aggregation devices (FADs) have been developed and used for more efficient capture of tunas (Scott & …
2009. TLDR. Estimates indicate that salmon farms attract and aggregate over 12 000 t of wild fish into a total of just 750 ha of coastal waters on any given day in Norway, with possible consequences of these persistent, substan- tial aggregations of wild fishes at farms. Expand. 151.

Fish Aggregation Devices (FADs) are man-made objects used to attract pelagic game fishing species such as yellowtail kingfish, southern bluefin tuna and dolphin fish. The use of FADs adds great value to our Victorian Game Fishing scene as they help to attract these open ocean going fish to a specific location and within easy access to boating ...
The use of fish aggregation devices (FADs) can increase catchability of tuna purse seine for associated tuna schools. In the past decades, large scale deployments of FADs have drawn the international attention due to their negative effects on the marine environment. Finding a FAD design ecologically …

The aim of this research was to assess marine litter abundance and its effects on the benthic fauna in an area of the central Mediterranean Sea exploited by fisheries using fish aggregating devices (FAD). The study was carried out by means of a remotely-operated vehicle (ROV).
12.7.1.3 Fish Aggregating Devices Fishery. To ensure sustainability in fishery, various incentives have been introduced to divert fishing efforts from coastal fishing zones to deep sea fish aggregating devices (FADs) and demersal fisheries. Despite, certain traditional fishers are reluctant to adopt new technology and shift to other ...
submerged in waters. Recognizing their importance and potential, fishermen adopted the device with modifications to suit the differeht types of fishes caught, fishing methods and techniques. A FAD is any object on construction for the purpose of facilitating the aggregation and attraction of fish for harvest using various types of fishing gears.
Fish aggregation devices (FADs) are used worldwide to enhance the efficiency of various fisheries. Devices usually consist of a floating or subsurface component designed to exploit natural fish ...
Fish aggregating devices (FADs) are big floating rafts in the middle of the ocean used to concentrate fish in one location to make them easier to catch. Some FADs are moored close to shore, but most are drifting in the open ocean targeting pelagic species like tuna, swordfish, and mahi mahi. Purse seine vessels affix FADs with electronic ...
Abstract. The structure, materials and designs of drifting Fish Aggregating Devices (dFADs) have generally remained rudimentary and relatively unchanged since they first came into use in the 1980 s. However, more recently, dFADs have been increasing in dimensions and the prevailing use of plastic components.
The performance of cage fish farms as fish aggregation devices (FAD) is well known in the marine environment (Dempster et al., 2002; Sanchez-Jerez et al., 2011) and is mainly related to the ...
Abstract. In the past two decades, drifting fish aggregation devices (FADs) have revolutionized pelagic fisheries, and are now responsible for the majority of tuna purse seine catches. Here, we argue that by taking advantage of the same proven aggregative properties, FADs could be used to enhance the benefits provided by blue water marine ...

Fish Aggregating Devices (FADs) are man-made, usually floating wooden structures with hanging nets to attract fish. These rafts can either be free floating (known as drifting FADs or dFADs) or anchored to the seabed (known as anchored FADs or aFADs). Some tuna fisheries also target natural structures or objects, including free-floating logs ...
Maui's Fish Aggregation Devices (FADs) It has long been known that pelagic fishes will aggregate to floating objects like logs, nets, and other debris. However, these objects drift around and may only be occasionally encountered by lucky fishermen. Researchers have found that anchoring a buoy or platform in the open ocean will also attract ...
We reviewed the literature concerning fish aggregation devices (FADs) to determine areas of relative research deficiency. Using specific searches of the Aquatic Sciences and Fisheries Abstracts (ASFA) database from 1978 to December 2003 and a classical search of the pre-1978 literature, we collected 407 references on FADs. …
