Safe Weekly Amounts of Mercury in Fish
Safe weekly amounts of mercury in fish Florida testing for mercury in a variety of fish is helpful for calculating the amount of seafood a person can eat, and still stay within the EPA Reference Dose for mercury – the amount of mercury a person can consume on a continuing basis without fear of ill effects. Safe amounts of fish are calculated by weekly doses. Amounts are cumulative; each meal must be counted against the weekly reference dose. Mercury amounts vary from fish to fish, and the averages below should serve only as guidelines. How to use the chart When calculating weekly allowances of fish, refer to the box closest to your weight and see the safe amount in ounces (a typical serving of fish is about 6 ounces). For instance, if you weigh 150 pounds you should limit yourself to 4.6 ounces per week of Red Grouper. For Snook you could eat no more than 4.2 ounces per week. To eat more than one kind of fish or more than one fish meal per week, you would want to select species with high allowances, such as mullet (72.4 ounces per week) or sand bream (22.4 ounces).

Before the Secretary of Commerce Petition to List the Pacific Bluefin Tuna
Credit: aes256 [CC BY 2.1 jp] via Wikimedia Commons Before the Secretary of Commerce Petition to List the Pacific Bluefin Tuna (Thunnus orientalis) as Endangered Under the Endangered Species Act June 20, 2016 6/20/2016 EXECUTIVE SUMMARY Petitioners formally request that the Secretary of Commerce, through the National Marine Fisheries Service (NMFS), list the Pacific bluefin tuna (Thunnus orientalis) as endangered or in the alternative list the species as threatened, under the federal Endangered Species Act (ESA), 16 U.S.C. §§ 1531 – 1544. Pacific bluefin tuna are severely overfished, and overfishing continues, making extinction a very real risk. According to the 2016 stock assessment by the International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean (ISC), decades of overfishing have left the population at just 2.6% of its unfished size. Recent fishing rates (2011-2013) were up to three times higher than commonly used reference points for overfishing. The population’s severe decline, in combination with inadequate regulatory mechanisms to end overfishing or reverse the decline, has pushed Pacific bluefin tuna to the edge of extinction. Pacific bluefin tuna are important apex predators in the marine ecosystem and must be conserved. They are one of three bluefin tuna species. These three species are renowned for their large size, unique physiology and biomechanics, and capacity to swim across ocean basins. They are slow-growing, long-lived, endothermic fish. The Pacific bluefin migrates tens of thousands of miles across the largest ocean to feed and spawn, ranging from waters north of Japan to New Zealand in the western Pacific and off California and Mexico in the eastern Pacific. -

Atlantic Mackerel (Scomber Scombrus)
Atlantic Mackerel (Scomber scombrus) Family Scombridae, Mackerels Common names: Mackerel, Boston mackerel, tinker Description: Atlantic mackerel are iridescent blue green above with a silvery white underbelly. Twenty to thirty black bars run across the top half of their body, giving them a distinctive appearance. The efficient spindle shape of their body and their strong tall fin give this fish its ability to move swiftly through the water. Atlantic mackerel have two separate large dorsal fins and, like their relatives the tunas, they possess several dorsal and anal finlets. On average, Atlantic mackerel weigh less than one pound, but individuals of up to two pounds are not unusual. Where found: Inshore and offshore Similar Gulf of Maine species: Chub mackerel, bonito Remarks: Atlantic mackerel are seasonal migrators that travel in dense schools. They appear in late spring in many of the state's harbors, coves and coastal rivers where they are sought by eager anglers. An ultralight to light spinning rod outfitted with 10 to 12 pound or less test line provides anglers with the most action. Spoons, spinners, weighted bucktails, jigs and tube lures all work well. Atlantic mackerel are not only enjoyed as table fare, but are especially prized as bait for other game fish.

Swimming Speeds of Marine Fish in Relation to Fishing Gears
ICES mar. Sei. Symp.. 196: 183-189. 1993 Swimming speeds of marine fish in relation to fishing gears Pingguo He He, P. 1993. Swimming speeds of marine fish in relation to fishing gears. - ICES mar. Sei. Symp., 196: 183-189. Swimming ability plays a vital role in the survival of fish in terms of catching a prey and escaping from a predator or a fishing gear. Knowledge of how fish swim and how well they can swim is very important in the design and operation of selective and energy- conserving commercial fishing gears, and in fisheries resource assessment through better understanding of selectivity and efficiency of survey trawls. This paper summar izes recent findings of swimming performance in marine fishes and discusses how a change in swimming ability due to biological and environmental conditions and how a change in trawl operation can influence the size selectivity of a trawl. Special attention is paid to commercially important species, including mackerel (Scomber scombrus), herring (Clupea harengus), cod (Gadus morhua), and saithe (Pollachius virens).
