Signature of Global Warming on Dynamics of Anchovy Engraulis Japonicus Stock in the Yellow Sea 2017 PICES MEETING, VLADIVOSTOK, RUSSIA Signature of Global Warming on Dynamics of Anchovy Engraulis japonicus Stock in the Yellow Sea Xiu-juan Shan, Xian-shi Jin, Yun-long Chen, Tao Yang Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Qingdao 266071; Laboratory for Marine Fisheries Science and Food Production Processes, Qingdao National Laboratory for Marine Science and Technology, Qingdao 266237; Yellow Sea Fisheries Research Institute 1 The oceans are changing rapidly Global “warming unequivocal” “Very high confidence that due to forcing by human activities”；By 2100, temperatures could increase by 1.1°C – 6.4°C Sea levels may rise by 18 to 59 cm. Recent studies (Nature geoscience & Science) suggests sea level rise could be at 80 to 200 cm Help!!! Climate change Atmospheric surface temperature anomaly (average 2005-2015 relative to 1951-1980) The rapid warming in 1982–2006 was confined to the Subarctic Gyre, European Seas, and East Asian Seas. The most rapid warming was observed in the land-locked or semi-enclosed European and East Asian Seas (Baltic Sea, North Sea, Black Sea, Japan Sea/East Sea, and East China Sea) and also over the Newfoundland–Labrador Shelf. (Belkin, 2009) Data source: NASA SST warming in the Yellow Sea SST in the Yellow Sea increased by 0.67 during 1982-2006 (Belkin,2009） ℃ SST in the Yellow Sea increased by 1.4-1.9 during 1977-2007, the rise of SST gradulately increased from the Yellow ℃Sea to the Bohai Sea(Huang, 2010) Effects of Climate change on fish Marine Fisheries Directly affect Fish Production Hydrology Rainfall Temperature Anchovy in the Yellow Sea Multi-stressors during anchovy life history Reclamati on Spawning， Hatching Pollution Fish larvae and juvenile feeding Overfishi ng Overwintering Climate change Anchovy Japanese anchovy in the YS showed opposite changing trend when compared with northern anchovy Japanese anchovy in Yellow Sea Jia & Sun, 2008 Water temperature significantly impacted anchovy distribution 0 17-2000 17-2200 18-0000 18-0200 18-0400 18-0600 18-0800 18-1000 18-1200 18-1400 18-1600 18-1800 18-2000 -5 20.5 20 19.5 19 -10 18.5 18 17.5 17 -15 16.5 16 15.5 -20 15 14.5 （35°01.9′N、120°32.9′E 14 13.5 -25 13 海区） 12.5 -30 1 2 3 4 5 6 7 8 9 10 11 12 13 600 500 网） / 400 300 200 鳀鱼鱼卵数量（粒 100 Amount of anchovy eggs (Ind./haul) of anchovy Amount 0 20 22 0 2 4 6 8 10 12 14 16 18 20 观测时间 Time of observation 下混合层 温跃层 上混合层 下混合层 温跃层 上混合层 下混合层 温跃层 上混合层 100.00 100.00 100.00 ° ′ 、 35°00.3′N 、 35 01.9 N 35°03.1′N 、 80.00 80.00120°32.9′E ） 80.00 120°41.0′E 120°25.9′E % 65.22 % 64.56 % 60.00 82.59 % 60.00 60.00 40.00 40.00 5.49 % 40.00 20.00 鳀鱼卵数量（％） 20.00 20.00 鳀鱼卵数量（％） 29.09 % 鳀鱼卵数量（ 6.35 % 11.92 % 22.15 % 0.00 0.00 0.00 12.63 % Z1 Z2 Z3 Z4 Z5 Z6 Z7 Z8 Z9 Z10 Z11 Z3-1Z12Z3-3Z13Z3-5 Z3-7 Z3-9 Z5 Z9 Z12 Z16 Z20 Z24 Z28 Z32 Z36 Z40 Z44 Z47 Z51 Z3-11 Z2-13 Z3-15 Z3-17 Z3-19 Z3-21 Z3-23 Z3-25 Z3-27 Z3-29 Z3-31 观测站位 观测站位 观测站位 （Wan et al，2008） 2002年6月20-21日水团追踪观测 2003年6月17-18日水团追踪观测 2003年6月27-30日水团追踪观测 鳀鱼卵数量的空间分布 鳀鱼卵数量的空间分布 鳀鱼卵数量的空间分布 Mortality of Japanese anchovy egg Natural Egg number Sea areas Survey time mortality rate （ind） （％） 2000/06/13-06/18 28,907 83.41 2001/05/16-07/6 86,872 84.87 Southern Shandong 2002/06/05-06/20 51,231 81.34 peninsula 2003/06/11-06/17 175,115 80.42 2004/06/10-06/19 124,510 75.22 Since the 1990s, the mortalityTotal of Japanese466,635 anchovy egg80.15 2006/09 344 77.33 Yellow in Sea the Yellow Sea greatly2007/08 increased-- 3,473 77.66 1985-1988 （64%） Total 3,817 77.63 2003/05 116,194 82.52 1998-2000（83%） 2004/05 8,391 87.7 2005/06 4,311 70.38 Laizhou 2000 Bay- 2008（77-88%） 2006/05 11,575 87.02 2008/05-06 10,035 84.68 Total 150,506 82.95 East China Sea and 2001/03/26-04/24 14,379 88.09 Yellow Sea Yellow Sea 1998/05/15-2000/12/18 59,838 83.57 1998/05/25-10/16 118,933 91.33 Bohai Sea 1992/08/08-1993/06/07 2,722,102 85.61 Yellow Sea 1985/03/11-1988/06/14 800,999 64.10 Data source from YSFRI Interannual changes of anchovy Biomass biomass in the Yellow Sea 4.5 4.0 3.5 3.0 2.5 2.0 百万吨 1.5 1.0 0.5 0.0 2001 2002 2003 2004 2005 2006 2008 2010 1986.1 1986-87 1987-88 1988-89 1989-90 1990-91 1991-92 1992-93 1993-94 1995-96 1998-99 1999-00 1984-85 1994-95 Zhao, X等. 2003..

  • European Anchovy Engraulis Encrasicolus (Linnaeus, 1758) From
    European anchovy Engraulis encrasicolus (Linnaeus, 1758) from the Gulf of Annaba, east Algeria: age, growth, spawning period, condition factor and mortality Nadira Benchikh, Assia Diaf, Souad Ladaimia, Fatma Z. Bouhali, Amina Dahel, Abdallah B. Djebar Laboratory of Ecobiology of Marine and Littoral Environments, Department of Marine Science, Faculty of Science, University of Badji Mokhtar, Annaba, Algeria. Corresponding author: N. Benchikh, [email protected] Abstract. Age, growth, spawning period, condition factor and mortality were determined in the European anchovy Engraulis encrasicolus populated the Gulf of Annaba, east Algeria. The age structure of the total population is composed of 59.1% females, 33.5% males and 7.4% undetermined. The size frequency distribution method shows the existence of 4 cohorts with lengths ranging from 8.87 to 16.56 cm with a predominance of age group 3 which represents 69.73% followed by groups 4, 2 and 1 with respectively 19.73, 9.66 and 0.88%. The VONBIT software package allowed us to estimate the growth parameters: asymptotic length L∞ = 17.89 cm, growth rate K = 0.6 year-1 and t0 = -0.008. The theoretical maximum age or tmax is 4.92 years. The height-weight relationship shows that growth for the total population is a major allometry. Spawning takes place in May, with a gonado-somatic index (GSI) of 4.28% and an annual mean condition factor (K) of 0.72. The total mortality (Z), natural mortality (M) and fishing mortality (F) are 2.31, 0.56 and 1.75 year-1 respectively, with exploitation rate E = F/Z is 0.76 is higher than the optimal exploitation level of 0.5.

    Food and Agriculture Organization of the United Nations Fisheries and for a world without hunger Aquaculture Department Species Fact Sheets Engraulis japonicus (Temminck & Schlegel, 1846) Black and white drawing: (click for more) Synonyms Engraulis japonicus Fowler, 1941d:694, (or incorrectly japonica ; Engraulis is masculine), (Japan, Korea, large synonymy). Atherina Japonica Houttuyn, 1782:340 (= nomen dubium - see Note below). Stolephorus celebicus Hardenberg, 1933a:262 (Manado, Sulawesi). FAO Names En - Japanese anchovy, Fr - Anchois japonais, Sp - Anchoíta japonesa. 3Alpha Code: JAN Taxonomic Code: 1210600202 Scientific Name with Original Description Engraulis japonicus Temminck & Schlegel, 1846, Fauna Japonica, Poiss., pt.13:239, pl. 108, fig.3 (southwest Japan). Diagnostic Features Differs very little from the European anchovy (see Engraulis encrasicolus ) and can be identified from that description. Of other anchovies found in the southern part of its distribution, only species of Encrasicholina and Stolephorus are similar in appearance (slender, rather round-bodied), but all have small spine like scutes before the pelvic fins (usually 2 to 7 scutes, but occasionally 1 or very rarely none in S. commersonii ). Species of Thryssa have compressed bodies and a keel of scutes along the belly.
