Do Some Atlantic Bluefin Tuna Skip Spawning?
SCRS/2006/088 Col. Vol. Sci. Pap. ICCAT, 60(4): 1141-1153 (2007) DO SOME ATLANTIC BLUEFIN TUNA SKIP SPAWNING? David H. Secor1 SUMMARY During the spawning season for Atlantic bluefin tuna, some adults occur outside known spawning centers, suggesting either unknown spawning regions, or fundamental errors in our current understanding of bluefin tuna reproductive schedules. Based upon recent scientific perspectives, skipped spawning (delayed maturation and non-annual spawning) is possibly prevalent in moderately long-lived marine species like bluefin tuna. In principle, skipped spawning represents a trade-off between current and future reproduction. By foregoing reproduction, an individual can incur survival and growth benefits that accrue in deferred reproduction. Across a range of species, skipped reproduction was positively correlated with longevity, but for non-sturgeon species, adults spawned at intervals at least once every two years. A range of types of skipped spawning (constant, younger, older, event skipping; and delays in first maturation) was modeled for the western Atlantic bluefin tuna population to test for their effects on the egg-production-per-recruit biological reference point (stipulated at 20% and 40%). With the exception of extreme delays in maturation, skipped spawning had relatively small effect in depressing fishing mortality (F) threshold values. This was particularly true in comparison to scenarios of a juvenile fishery (ages 4-7), which substantially depressed threshold F values. Indeed, recent F estimates for 1990-2002 western Atlantic bluefin tuna stock assessments were in excess of threshold F values when juvenile size classes were exploited. If western bluefin tuna are currently maturing at an older age than is currently assessed (i.e., 10 v. -
NOAA's Description of the U.S Commercial Fisheries Including The
6.0 DESCRIPTION OF THE PELAGIC LONGLINE FISHERY FOR ATLANTIC HMS The HMS FMP provides a thorough description of the U.S. fisheries for Atlantic HMS, including sectors of the pelagic longline fishery. Below is specific information regarding the catch of pelagic longline fishermen in the Gulf of Mexico and off the Southeast coast of the United States. For more detailed information on the fishery, please refer to the HMS FMP. 6.1 Pelagic Longline Gear The U.S. pelagic longline fishery for Atlantic HMS primarily targets swordfish, yellowfin tuna, or bigeye tuna in various areas and seasons. Secondary target species include dolphin, albacore tuna, pelagic sharks including mako, thresher, and porbeagle sharks, as well as several species of large coastal sharks. Although this gear can be modified (i.e., depth of set, hook type, etc.) to target either swordfish, tunas, or sharks, like other hook and line fisheries, it is a multispecies fishery. These fisheries are opportunistic, switching gear style and making subtle changes to the fishing configuration to target the best available economic opportunity of each individual trip. Longline gear sometimes attracts and hooks non-target finfish with no commercial value, as well as species that cannot be retained by commercial fishermen, such as billfish. Pelagic longline gear is composed of several parts. See Figure 6.1. Figure 6.1. Typical U.S. pelagic longline gear. Source: Arocha, 1997. When targeting swordfish, the lines generally are deployed at sunset and hauled in at sunrise to take advantage of the nocturnal near-surface feeding habits of swordfish. In general, longlines targeting tunas are set in the morning, deeper in the water column, and hauled in the evening. -
Atlantic Bluefin Tuna
QUALITY STATUS REPORT 2010 Case Reports for the OSPAR List of threatened and/or declining species and habitats – Update Nomination and biomass of older fish since 1993. The reported catch for the East Atlantic and Atlantic bluefin tuna Mediterranean stocks in 2000 was 33,754 MT, Thunnus thynnus about 60% of the peak catch in 1996 although this is probably an under-estimate because of increasing uncertainty about catch statistics (ICCAT, 2002). The best current determination of the state of the stock is that the Spawning Stock Biomass is 86% of the 1970 level. This is similar to the results obtained in 1998 in terms of trends, but more optimistic in terms of current depletion. Nevertheless, the International Commission for the Conservation of Atlantic Tunas (ICCAT) Geographical extent considers that current catch levels are not OSPAR Regions: V sustainable in the long-term (ICCAT, 2002).

The Story of Atlantic Bluefin Tuna Is One of Intrigue, Filled with International Drama, Mafia Connections, and Plot Twists Worthy of a Movie
A brief from Sept 2017 Richard Herrmann The Story of Atlantic Bluefin Science-based management will ensure a healthy future Overview The story of Atlantic bluefin tuna is one of intrigue, filled with international drama, mafia connections, and plot twists worthy of a movie. The main character—Thunnus thynnus—is the largest and most athletic tuna, which can grow to the size of a small car and travel nearly as fast as one too. An Atlantic bluefin starts out no bigger than an eyelash and grows to several hundred pounds and more than 6 feet in length in less than a decade. Unlike most fish species, Atlantic bluefin are warm-blooded; the heat created in their huge swimming muscles enables bursting speed, sharp vision, and thought processing second to none in the fish world. They are among the Atlantic’s top predators, with few species they won’t eat—and even fewer that eat them. The fleets of fishing vessels plying the Atlantic—and hoping to cash in on the value that the species has in sushi markets in Japan and high-end restaurants around the world—present the greatest threat to the Atlantic bluefin. Fishermen are often paid more than $10,000 for a single Atlantic bluefin right at the dock. The value of a high- quality fish at the final point of sale can be tens of thousands of dollars. These transactions add up to be big business. A recent estimate set the value of Atlantic bluefin fishing at nearly $200 million at the dock in 2014— and over $800 million at the final point of sale.1 Experts estimate that, pound for pound, this species is the most valuable tuna in the world and likely the most valuable fish in the Atlantic Ocean or the Mediterranean Sea. -

Variability in Trawl Survey Catches of Pacific Ocean Perch, Shortraker Rockfish, and Rougheye Rockfish in the Gulf of Alaska David M
Biology, Assessment, and Management of North Pacific Rockfishes 411 Alaska Sea Grant College Program • AK-SG-07-01, 2007 Variability in Trawl Survey Catches of Pacific Ocean Perch, Shortraker Rockfish, and Rougheye Rockfish in the Gulf of Alaska David M. Clausen and Jeffrey T. Fujioka National Marine Fisheries Service, Auke Bay Laboratory, Juneau, Alaska Abstract Little information is available on the comparative variability of Pacific ocean perch, shortraker rockfish, and rougheye rockfish catches in Alaska trawl surveys. In this study, data were first examined for these three species from three localized experimental bottom trawl surveys in the Gulf of Alaska in 1993, 1998, and 1999 to compare the variability of catch rates for each species. When catch rates were analyzed within favorable fishing areas for each species, the coefficients of variation for Pacific ocean perch were approximately 2.5 to 3 times greater than those of shortraker or rougheye rockfish, indicating that the latter two species are much more even in their distribution. To provide a broader comparison of variability, catch rates of the three species were also examined from seven large-scale bottom trawl surveys conducted in the Gulf of Alaska from 1984 to 2001. Using geographic information systems software, subsets of the hauls in these surveys were selected in what were determined to be favorable fishing areas for either Pacific ocean perch or for shortraker and rougheye rockfish. Analysis of the species’ catch rates in these hauls indicated results that were very simi- lar to those of the experimental trawl surveys; the variability of Pacific ocean perch was 2.1-2.3 times greater than that for either shortraker or rougheye rockfish.
