10. II. Major Fisheries - by Fish THE FIRST TIER Peruvian Anchovy Alaskan Pollock Skipjack Tuna Capelin

11. Figure 3.2. Historical Catches of: (A) Peruvian Anchovy; (B) Alaska Pollock; (C) Skipjack Tuna; and (D) Capelin. Note the different scales on the y axes!

12. Peruvian Anchovy Not heavily fished until the 1950s Susceptible to disruptions by ENSOs By 1970, the largest fishery in the world Lessons may have been learned

15. Alaskan Pollock Not heavily fished until the 1960s Overfishing a real concern Improvements in processing ability were important Monitoring and managing techniques may be improving

17. Skipjack Tuna Another recently developed fishery This resource may be underutilized Catches are trending upwards Monitoring and managing techniques are a challenge

20. Capelin Yet another recently developed fishery An equlibrium may be being attained An early peak, a characteristic of some new fisheries This fishery is dominated by two relatively cooperative countries

22. The bulk of the capelin catch goes for reduction into meal and oil, which is mostly used for production of animal feed, including salmon feed. But a part of the catch finds a market outlet in Japan where capelin is a popular snack and capelin roe is sought-after in Japan for its alleged aphrodisiac properties. Capelin are members of the Osmeridae family of smelts. They are known as sparling in England. Capelin are slender translucent olive colored, small-scaled fish that grow to a maximum length of 25 cm (10 in). Capelin was once the primary food of cod in the North Atlantic. When the cod population diminished the capelin population increased dramatically. The species is found from the surface and down to depths of 300 metres. During spawning, the male holds on tightly to the female with its pectoral and ventral fins and swims down towards the bottom. The majority die after spawning and only a few live to spawn a second time.

23. II. Major Fisheries - by Fish THE SECOND TIER Atlantic Herring Japanese Anchovy Chilean Jack Mackerel Blue Whiting

24. Figure 3.3. Historical Catches of: (A) Atlantic Herring; (B) Japanese Anchovy; (C) Chilean Jack Mackerel; and (D) Blue Whiting.

25. Atlantic Herring An old fishery - based on gill netting Effective management may result in a stable fishery Introduction of purse seine technology resulted in increased but unsustainable yields

28. Japanese Anchovy A fishery with a long history of catch records Current high catch may not be sustainable Stable until the entry of the Chinese into the fishery

30. Japanese Anchovy A fishery with a long history of catch records Current high catch may not be sustainable Stable until the entry of the Chinese into the fishery “Alternatively, current high catch may not be real”

31. Chilean Jack Mackerel This fishery began with the collapse of the Peruvian Anchovy It was subject to initial overexploitation The current yield may be sustainable; Stable at 2 million tonnes from 2002 through 2008

33. Blue Whiting A relatively recent fishery Unregulated until recently Recent increases in catch are recognized as unsustainable

35. Blue Whiting 2005. EU, Faeroes, Iceland, Norway, agree on a management plan A limit of 2 million tonnes set for 2006 Agreement on reduced limits, to 540,000 tonnes by 2010

36. Blue Whiting Until these multi-national agreements, Blue Whiting was exclusively used for reduction, to fish oil and animal feed. With the new, lower, catch limits, attempts are being made to “add value” to this fishery.

37. Blue whiting (Micromesistius poutassou). Length to 30-35 cm. Weight 150- 300 grams.

38. III. Major Fisheries - by Nation THE FIRST TIER China Peru United States Indonesia

40. China From 1989 to 1998, 1 MT/yr increases were reported From 1998 on, 0 MT/yr increases were reported Virtual Biology

42. Peru Catch dominated by a single species ENSO is not a manageable threat Overfishing is a manageable threat

43. United States Stable since 200 mile EEZ established Inshore trawl catch isn’t well identified Indonesia Offshore tuna catch is 75% of fishery

44. III. Major Fisheries - by Nation THE SECOND TIER Japan Chile India Russia

46. Japan and Russia Declines a consequence of the EEZ Decline a consequence of drops in catches of two heavily fished species Chile 21% of catch is from inland waters India The Bombay Duck

47. Also called bummalo, Bombay Duck is a marine lizardfish, Harpodon nehereus, from southern Asia, particularly abundant in the Ganges Delta and the Arabian Sea of western India. It is a narrow, usually 6 to 8 inches long, slimy fish. It is caught in November and December; the processing goes on from December until March.

50. V. WHAT’S THE WORLD COMING TO? Possible Future Fisheries? I.Krill II.Myctophids III.Squid

51. Krill - What is it? Euphausia superba

53. Krill - the fishery First harvested by USSR in the 1960s Japan, South Korea, and Norway are now the main fishers An average of 118,000 tonnes per year harvested from 1999-2008

54. Krill - Some Issues Very important harvester of primary productivity in the Southern Ocean - Phytoplankton and “Ice Algae” Loss of Ice May Impact Stocks Palatability and Processing Problems If Problems are Solved, Overharvesting is Possible

55. Krill - Some Issues Management Put in Place in 1981 Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR) Stock Estimate: 37 Million Metric Tons Total Allowable Catch: 3.47 MT Harvest Average: 118,000 MT

56. Small Mesopelagics - What are they? Myctophids, or, Lanternfish Myctophum punctatum

57. Small Mesopelagics - the fishery 100 million tonne potential, but - Not much of a fishery because - Wide horizontal dispersal within the ecosystem.

58. Squid and Other Cephalopods Loligo vulgaris

59. Squid Fisheries Near-shore - a number of fisheries over continental shelves. A vast world-wide pelagic fishery, ~100 million tons per year. This fishery is dominated by Sperm Whales. Pelagic fishery could probably withstand a human harvest of 25 million tonnes per year.

60. VI. Economic Values Fish eaten by humans have high market value Fish used for reduction have low market value
