A Valuation of Tuna in the Eastern Pacific Ocean
A fact sheet from July 2016 Gerard Soury Netting Billions: A Valuation of Tuna in the Eastern Pacific Ocean Overview Together, the seven most commercially important tuna species are among the most economically valuable fish on the planet. Globally, commercially landed tuna product has a value of US$10 billion to $12 billion per year to the fishermen that target tunas and more than US$42 billion per year at the final point of sale. These conservative totals do not account for noncommercial values of tuna, including those associated with sport fishing, other forms of tourism, and the ecosystem benefits of living tunas.

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. -
Estimating Age and Growth of Little Tunny, Euthynnus Alletteratus, Off the Coast of Senegal, Using Dorsal Fin Spine Sections
SUMMARY PAPER Estimating Age and Growth of Little Tunny, Euthynnus alletteratus, off the Coast of Senegal, Using Dorsal Fin Spine Sections PATRICE M. CAYRE 1 and TAIB DIOUP ABSTRACT Estimates of age were made from counts of growtb bands on dorsal spine sections of 491 little tunny, Euthynnus alletteratus, captured off the coast of Senegal during 1979. Analysis of marginal growtb bands (by montb) indicates that these bands are probably formed during tbe cold season (November-May). Mean size at estimated age was deter mined for tbe first 8 yr of life. These results, tbougb not validated, closely approximated other studies for young fisb (estimated ages 1-3), but were bigbly variable for older age categories. Tbe index of average percent error (E) for age nates from our study was 10.5% and infers good precision.

Measured from tip of lower jaw to tail fork. 1 Aggregate limit for Lane and Vermilion snappers, Gray trigger- fish, Almaco jack, and Tilefishes is 20/day. 2 Offshore landing permit: Tuna, Billfish, Swordfish, Amberjacks, Grouper, Hinds and Snapper (non-grey). 3 Must report Yellowfin Tuna landings. 4 Aggregate limit for all groupers (except Nassau, Goliath Warsaw, and Speckled hind) is 4/day. Check for seasons. All saltwater fish except tuna, garfish, and swordfish in possession must have the head and tailfin intact when set or put on shore from a vessel. The skin must be left on these fish. Federal regu- lations require that tails are to be on tunas. For all saltwater fish, the bag limit is also the possession limit, except for redfish and speckled trout. A two-day limit of these two species is allowed in possession on land but not on the water. Fisheries regulations are subject to change often. At the time of this printing, these regulations were correct.

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).
