IGFA Angling Rules
International Angling Rules The following angling rules have been formulated by the International Game Fish Association to promote ethical and sporting angling practices, to establish uniform regulations for the compilation of world game fish records, and to provide basic angling guidelines for use in fishing tournaments and any other group angling activities. The word “angling” is defined as catching or attempting to catch fish with a rod, reel, line, and hook as outlined in the international angling rules. There are some aspects of angling that cannot be controlled through rule making, however. Angling regulations cannot insure an outstanding performance from each fish, and world records cannot indicate the amount of difficulty in catching the fish. Captures in which the fish has not fought or has not had a chance to fight do not reflect credit on the fisherman, and only the angler can properly evaluate the degree of achievement in establishing the record. Only fish caught in accordance with IGFA international angling rules, and within the intent of these rules, will be considered for world records. Following are the rules for freshwater and saltwater fishing and a separate set of rules for fly fishing. RULES FOR FISHING IN FRESH AND SALT WATER (Also see Rules for Fly fishing) E.

Myxospores are arcuate, 22.4 +/- 2.6 µm thick, 5.2 +/- 0.4 µm long, posterior angle 45 +/- 24°, with 2 sub-spherical polar capsules, diameter 2.3 +/- 0.2 µm, which lie adjacent to the suture. Its ribosomal small subunit sequence was most similar to an intestinal parasite of salmonid fishes, Ceratomyxa shasta (97%, 1,671/1,692 nt), and distinct from all other Ceratomyxa species (<85%), which are typically coelozoic parasites in the gall bladder or urinary system of marine fishes. -

A Few Words About Mercury from Wild Planet Foods
A Few Words About Mercury from Wild Planet Foods Wild Planet recognizes that dietary choices affect the health and well-being of ourselves and our families. It is vital that these decisions be guided by accurate, credible information. It is a weighty responsibility to advise and influence the consumption choices of others, as this is best left to governmental authorities and health professionals. For this reason, Wild Planet has shared information cautiously on the issue of methylmercury (MeHg) content in its tuna. We have stated since 2001 that the younger, migratory pole and line caught albacore tuna canned by Wild Planet are lower in mercury than older, long-line caught albacore. Wild Planet has tested extensively its albacore tuna over the last 16 years and has found that more than 99% of test results fall below 0.3 parts per million (ppm) total mercury, and no test result exceeded 0.4ppm. By comparison, the FDA has mandated a cautionary level of 1.0ppm. There are no “dangerous” spikes of methylmercury content in pole and line caught albacore tuna, and any portrayal of wide variances is simply not accurate. This is corroborated by a definitive, independent study of West Coast albacore tuna by Oregon State University. Wild Planet has also stated that all skipjack light tuna is lower yet in methylmercury compared to albacore. This is true of all brands of skipjack light tuna available in the marketplace. Since 2015, there have been claims by other brands that some tuna sold in the market is individually tested for mercury with a proprietary, nearly-instant-read testing technology. -
8.2 the Significance of Ocean Deoxygenation for Open Ocean Tunas and Billfishes Shirley Leung,K

Mislan, Barbara Muhling and Richard Brill 8.2 The significance of ocean deoxygenation for open ocean tunas and billfishes Shirley Leung1,*, K. A. S. Mislan1,2, Barbara Muhling3,4 and Richard Brill5 1 School of Oceanography, University of Washington, USA. Email : [email protected] 2 eScience Institute, University of Washington, USA 3 University of California Santa Cruz, Santa Cruz, CA, USA 4 National Oceanic and Atmospheric Administration, National Marine Fisheries Service, Southwest Fisheries Science Center, La Jolla, CA, USA 5 Virginia Institute of Marine Science, Gloucester Point, VA, USA Summary • Tunas and billfishes should be especially sensitive to low ambient oxygen conditions given their high metabolic rates as well as the large differences between their resting and maximum metabolic rates. Although there are many behavioural similarities among the different species, there are also clear and demonstrable differences in growth rates, maximum adult size, physiological abilities, low-oxygen tolerances, and preferred environmental conditions. • Climate change is projected to alter oxygen concentrations throughout the open ocean, with most regions undergoing decreases due to a slowdown in ocean ventilation and a decline in surface oxygen solubility. Between 200 and 700 m depth (a vertical range including depths to which tunas and billfishes commonly descend to forage), the greatest and most certain decreases in oxygen concentrations are projected to occur in the North Pacific and much of the Southern Ocean, while the smallest and least certain changes are projected to occur within the tropical Pacific Ocean. -
Oncorhynchus Mykiss) (Salmoniformes: Salmonidae) Diet in Hawaiian Streams1
Pacific Science (1999), vol. 53, no. 3: 242-251 © 1999 by University of Hawai'i Press. All rights reserved Alien Rainbow Trout (Oncorhynchus mykiss) (Salmoniformes: Salmonidae) Diet in Hawaiian Streams1 MICHAEL H. KIDO,2 DONALD E. HEACOCK,3 AND ADAM ASQUITH4 ABSTRACT: Diet of rainbow trout, Oncorhynchus mykiss (Walbaum), intro duced by the State of Hawai'i into tropical headwater streams of the Waimea River in the Koke'e area ofthe Hawaiian island ofKaua'i, was examined in this study through gut content analysis. In Wai'alae Stream, rainbow trout were found to be opportunistic general predators efficient at feeding on invertebrate drift. Foods eaten ranged from juvenile trout, to terrestrial and aquatic arthro pods, to algae and aquatic mosses. Native aquatic species, particularly dragonfly (Anax strennus) and damselfly (Megalagrion heterogamias) naiads, lyrnnaeid snails (Erinna aulacospira), and atyid shrimp (Atyoida bisulcata), were deter mined to be major foods for alien trout. Terrestrial invertebrates (primarily ar thropods), however, provided a substantial (albeit unpredictable) additional food supply. Based on results of the study, it is cautioned that large numbers of rainbow trout indiscriminantly released into lower- to middle-elevation reaches ofHawaiian streams could do substantial damage to populations ofna tive aquatic species through predation, competition, and/or habitat alteration. RAINBOW TROUT, Oncorhynchus mykiss the high-elevation (ca. 3500 ft [1067 m]) Ko (Walbaum), along with several other Salmo ke'e area of Kaua'i Island (Figure I) (Need niformes (Salmonidae), were introduced into ham and Welsh 1953). By 1941, only Koke'e Hawaiian Island streams early in the century streams were being stocked.
