On the north-eastern coast of Sardinia, from November 2004 to January 2006, the first attempt in the Mediterranean basin to obtain information on encounter rate, group size and incidental capture of bottlenose dolphins in a marine fish farm was assessed, combining direct observations from fish farm boats with photo-identification studies. During 15 months of research, 79 d (65.3% of the total monitored days) were spent in direct observation of 146 groups of bottlenose dolphins around the fish… Expand
Bottlenose dolphins and aquaculture: interaction and site fidelity on the north-eastern coast of Sardinia (Italy)
TLDR
The occurrence of bottlenose dolphins appeared to be related with the seasons and with the fish farm harvesting operations, and the peak dolphin occurrence throughout Fall coincides with the period in which they spend most of their time foraging. Expand
Ecology of common bottlenose dolphins along the North-western Sardinian coastal waters (Italy)
ABSTRACT In this paper, the temporal distribution of dolphins, group dynamics, site fidelity and abundance of common bottlenose dolphins along the North-western coastal waters of Sardinia (Italy) wasExpand
Long-term acoustic monitoring of bottlenose dolphins, Tursiops truncatus, in marine protected areas in the Spanish Mediterranean Sea
Abstract The presence of bottlenose dolphins ( Tursiops truncatus ) was monitored with echolocation loggers (T-POD) for 12 months in seven Spanish Mediterranean Marine Protected Areas (MPA).Expand
Interaction between bottlenose dolphins (Tursiops truncatus) and artisanal fisheries in the Valencia region (Spanish Mediterranean Sea)
Abstract Coastal waters of the Valencia region are important habitats for bottlenose dolphins, but also important fishing grounds for artisanal fisheries. No studies have been carried out here toExpand
Ecology and conservation of common bottlenose dolphins Tursiops truncatus in the Mediterranean Sea
Bottlenose dolphins Tursiops truncatus are amongst the best-known cetaceans. In the Mediterranean Sea, however, modern field studies of cetaceans did not start until the late 1980s. BottlenoseExpand
Marine aquaculture and bottlenose dolphins’ (Tursiops truncatus) social structure
In this study, we investigate association patterns of 249 bottlenose dolphin feeding groups off Sardinia Island (Italy) from January 2000–May 2007 and describe how their association behaviour isExpand
The impact of shellfish farming on common bottlenose dolphins’ use of habitat
TLDR
New insights are provided into the understanding of how shellfish aquaculture influences coastal dolphins and hence support the design of policies aimed at implementing ecosystem management principles. Expand
Fish farming and its appeal to common bottlenose dolphins: modelling habitat use in a Mediterranean embayment
1. Common bottlenose dolphins Tursiops truncatus interact with fish farms in the Mediterranean Sea. These interactions were investigated in a Greek bay by incorporating multiple geographic,Expand
Comparison of local knowledge about the bottlenose dolphin (Tursiops truncatus Montagu, 1821) in the Southwest Atlantic Ocean: New research needed to develop conservation management strategies
Abstract The aim of this study was to compare the local knowledge of artisanal fishermen about interactions between the bottlenose dolphin (Tursiops truncatus) and fisheries in Brazil and Uruguay.Expand
Occurrence, abundance, range, and residence patterns of Tursiops truncatus on the coast of Aragua, Venezuela
Throughout the distribution of the bottlenose dolphin Tursiops truncatus, the occurrence, abundance, local distribution, and residential patterns are highly variable according to the pressure of theExpand

Interactions between Mediterranean bottlenose dolphins ( Tursiops truncatus ) and gillnets off Sardinia, Italy
TLDR
The extent of the estimated bycatch is worrisome in terms of the ability of bottlenose dolphins off Sardinia to sustain such an annual loss, and the distribution of daily encounter rate among seasons, group size, or number of immatures, in the presence or the absence of gillnets. Expand
Bottlenose Dolphin (Tursiops truncatus) Predation on a Marine Fin Fish Farm: Some Underwater Observations
TLDR
Underwater observations of bottlenose dolphin feeding behaviour in a marine fin fish farm on the Sardinian coast in Italy from 2000 to 2005 suggest that the use of different feeding strategies is consistent with the hypothesis that Bottlenose dolphins apply common decision rules in relation to prey availability, resulting in theUse of different foraging techniques.

The effects of aquaculture on bottlenose dolphin (Tursiops sp.) ranging in Shark Bay, Western Australia
TLDR
Long-term ranging patterns of adult female bottlenose dolphins are compared before and during full-scale pearl oyster farming operations to determine if they were displaced and suggest that shellfish aquaculture could have a large impact on small cetaceans. Expand

Abstract In recent years there has been growing concern about the environmental consequences of the rapidly expanding Scottish fish farm industry. One such concern is the control of fish predators. AExpand
Marine Mammals and Aquaculture: Conflicts and Potential Resolutions
TLDR
It is recommended that owing to potential for entanglement, chemical and sound pollution, habitat loss or gross alteration, traffic, and changes in species interactions, all proposed development of marine aquaculture in nature should be subjected to initial evaluations and scientific research relative to interactions between the food being raised by humans and the predators that attempt to take advantage of this.

A survey of antipredator controls at marine salmon farms in Scotland
TLDR
The survey suggests that the degrees of protection afforded by predator control methods vary appreciably between sites, and there is a need for a range of antipredator devices to be tested under controlled conditions to determine under which circumstances each is most effective. Expand

Salmon aquaculture facilities in Downeast Maine are occasionally attacked by harbor seals and gray seals. The predators kill and injure valuable fish and may damage net-pens allowing farm-fish toExpand

TLDR
The relationships of cetaceans with trawls need to be further studied to determine what effects the trawl fisheries have on the ecology and population status of the whales and dolphins involved. Expand
