Consumption Impacts by Marine Mammals, Fish, and Seabirds on The
83 Consumption impacts by marine mammals, fish, and seabirds on the Gulf of Maine–Georges Bank Atlantic herring (Clupea harengus) complex during the years 1977–2002 W. J. Overholtz and J. S. Link Overholtz, W. J. and Link, J. S. 2007. Consumption impacts by marine mammals, fish, and seabirds on the Gulf of Maine–Georges Bank Atlantic herring (Clupea harengus) complex during the years 1977–2002. ICES Journal of Marine Science, 64: 83–96. A comprehensive study of the impact of predation during the years 1977–2002 on the Gulf of Maine–Georges Bank herring complex is presented. An uncertainty approach was used to model input variables such as predator stock size, daily ration, and diet composition. Statistical distributions were constructed on the basis of available data, producing informative and uninformative inputs for estimating herring consumption within an uncertainty framework. Consumption of herring by predators tracked herring abundance closely during the study period, as this important prey species recovered following an almost complete collapse during the late 1960s and 1970s. Annual consumption of Atlantic herring by four groups of predators, demersal fish, marine mammals, large pelagic fish, and seabirds, averaged just 58 000 t in the late 1970s, increased to 123 000 t between 1986 and 1989, 290 000 t between 1990 and 1994, and 310 000 t during the years 1998–2002. Demersal fish consumed the largest proportion of this total, followed by marine mammals, large pelagic fish, and seabirds. Sensitivity analyses suggest that future emphasis should be placed on collecting time-series of diet composition data for marine mammals, large pelagic fish, and seabirds, with additional monitoring focused on the abundance of seabirds and daily rations of all groups. -

Seafood Watch defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. The program’s mission is to engage and empower consumers and businesses to purchase environmentally responsible seafood fished or farmed in ways that minimize their impact on the environment or are in a credible improvement project with the same goal. Each sustainability recommendation is supported by a seafood report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s Sustainability Criteria to arrive at a recommendation of “Best Choice,” “Good Alternative,” or “Avoid.” In producing the seafood reports, Seafood Watch utilizes research published in academic, peer-reviewed journals whenever possible. Other sources of information include government technical publications, fishery management plans and supporting documents, and other scientific reviews of ecological sustainability. Seafood Watch research analysts also communicate with ecologists, fisheries and aquaculture scientists, and members of industry and conservation organizations when evaluating fisheries and aquaculture practices. Capture fisheries and aquaculture practices are highly dynamic; as the scientific information on each species changes, Seafood Watch’s sustainability recommendations and the underlying seafood reports will be updated to reflect these changes. -

Conservation Advisory Science Notes No. 164, Department of Conservation, Wellington. Keywords: Whales, seals, food preparation (marine mammal), meat quality assessment (marine mammal), flensing, pathogens, contaminants Abstract Interest in the use of stranded whales as a source of food and the use of seals for cultural purposes has been expressed to the Department of Conservation by Ngati Hawea and Ngai Tahu Maori respectively. The known and anecdotal history of consumption of whale and seal meat in New Zealand and elsewhere is briefly discussed. Comments on the palatibility of marine mammal meat and the use of whales and seals as food are presented. Post-stranding damage and carcass contamination result in unsuitability of meat for human consump- tion. Criteria for the assessment of meat quality from stranded animals are presented. The transmission of parasites, particularly Anisakis sp., and the cumulative effects of persistent pesticides and heavy metals from consump- tion of meat from species such as pilot whales is discussed. Meat collection and storage should be conducted under the same conditions and constraints applied to terrestrial mammals. -

Sustainable Fishing: Orange Roughy
sustainable fishing: Orange Roughy Orange Roughy Ecology & Fishing: Classification and name Orange Roughy belong to the Trachichthydae family. Orange Roughy were originally known by the name ‘Slimehead’ but were renamed Orange Roughy as this was thought to be a more marketable name. Can you imagine ordering ‘Slimehead’ at a fancy restaurant? Scientific name: Hoplostethus atlanticus Common name: Orange Roughy Other name(s): Slimehead, Deep Sea Perch, Red Roughy Habitat and Distribution Orange Roughy are found deep in oceans around the world. They like to live in water over steep continental slopes and ocean ridges [beyond the continental shelf]. Orange Roughy can be found at depths of 750 to 1200 metres right around Aotearoa New Zealand, although the largest fisheries are south of the middle of the North Island. In Australia, Orange Roughy are found deep in in depths of 700 – 1400 metres around the bottom half of the country. Characteristics Orange Roughy are typically 30 – 50cm in length but can grow to 75cm in length. They typically weigh 0.8kg up to 3.5kg, although have been known to be as heavy as 7kg. Life cycle Orange Roughy are slow growing. In Aotearoa New Zealand Orange Roughy are thought to start reproducing at 23 to 31 years of age. In Australia, it is thought to be 1 27-32 years of age. Orange Roughy reproduce by spawning. Females spawn [release eggs] into the water over the period of about a week. Males spawn for a 1-2 week period. In Aoteaora New Zealand spawning happens between June and August and in Australia spawning occurs in July and August. -

Occurrence of Depredation by Common Bottlenose Dolphins
Occurrence of depredation by common bottlenose dolphins (Tursiops truncatus) on reef fish captured and released by rod and reel fisheries in the northeastern Gulf of Mexico by Corie E. Grewal Advisor: Dr. Andrew J. Read Prepared for: Jessica Powell, National Marine Fisheries Service April 30, 2021 Masters project submitted in partial fulfillment of the requirements for the Master of Environmental Management degree in the Nicholas School of the Environment of Duke University Executive Summary In the Gulf of Mexico, common bottlenose dolphins (Tursiops truncatus) have been observed depredating fish from rod and reel anglers. Depredation is defined as the removal of captured fish or bait by a predator, in this case bottlenose dolphins. Depredation can cause serious injury and mortality for dolphins who may become entangled or hooked in fishing gear and also increases the costs of fishing for anglers by forcing them to replace gear and bait, as well as the loss of catch to dolphins. Protected species managers in the Gulf are receiving an increasing number of reports about depredation from anglers and are hoping to gain more insight into how such interactions can be reduced. To better understand the nature and extent of these interactions, I examined potential factors that could influence the probability of depredation and the spatial distribution and frequency of such interactions. I analyzed data collected from the Florida Fish and Wildlife Conservation Commission (FWC) fisheries-dependent monitoring at-sea observer program to determine which factors played a role in rod and reel dolphin depredation of rod and reel fisheries between 2009 and 2020.
