چکیده
Project objectives and scientific hypotheses: Central to any successful fishery management plan is the availability of accurate, detailed and updated life history information on the species. Several reports, including the current spiny dogfish FMP, outline an extensive list of research needs that would help build a successful management plan for this species. Two of the most important questions regionally, is whether or not spiny dogfish in the Gulf of Maine should be considered as part of the NW Atlantic stock and what areas of the Gulf of Maine are represent essential fish habitats for this species. Satellite tags offer a means to study the real time movement patterns and how an animal utilizes its environment. The success of this technique on several marine species, suggest that the use of this technology will provide insight into dogfish movements and habitat use in the Gulf of Maine. If the method in this pilot effort proves successful, the use of these techniques may be expanded to determine whether or not spiny dogfish should be considered a unit stock in Gulf of Maine and the determination of EFH for this species. Thus our goals are to test the feasibility of using satellite tag technology to track spiny dogfish movement in the Gulf of Maine.

Spiny dogfish (Squalus acanthias) are assumed to be a highly migratory species, making habitual north-south migrations throughout their northwestern Atlantic United States (U.S.) range. Also assumed to be a benthic species, spiny dogfish stock structure is estimated through Northeast Fisheries Science Center (NEFSC) bottom-trawl surveys. Recent anomalies in population trends, including a recent...

The spiny dogfish (Squalus acanthias) is a temperate, coastal squaloid shark with an antitropical distribution in the Atlantic and Pacific oceans. The global population structure of this species is poorly understood, although individuals are known to undergo extensive migrations within coastal waters and across ocean basins. In this study, an analysis of the global population structure of the s...

Five spiny dogfish were captured in early-mid May during gillnet and longline sampling targeting juvenile coastal sharks in inshore North Carolina waters. Dogfish captures were made within Back Sound and Core Sound, North Carolina. All dogfish were females measuring 849-905 mm total length, well over the size at 50% maturity. Dogfish were caught at stations 1.8-2.7 m in depth, with temperature...

Changes in the feeding mechanism with feeding behavior were investigated using high-speed video and electromyography to examine the kinematics and motor pattern of prey capture, manipulation and transport in the spiny dogfish Squalus acanthias (Squalidae: Squaliformes). In this study, Squalus acanthias used both suction and ram behaviors to capture and manipulate prey, while only suction was us...
