Biological and physical surveys were conducted in order to investigate the relationship between envi-ronmental conditions and the distribution of moon jelly?sh Aurelia aurita in Hiroshima Bay,western Seto Inland Sea,Japan.Moon jelly?sh and ichthyoplankton were collected at 13stations in Hiroshima Bay during monthly surveys from July to September in 2006and 2007.Surface temperature in 2006was signi?cantly lower during the August and September cruises and surface salinity was lower during all cruises than in 2007.Moon jelly?sh was the most dominant gelatinous plankton collected,accounting for 89.7%in wet weight.Mean moon jelly?sh abundance in 2006was higher than that in 2007from July through September,with signi?cant inter-year differences for July and September.Variability in precipitation and nutritional input from the Ohta River,northernmost part of Hiroshima Bay,were suggested as possible factors affecting the inter-annual variability in moon jelly?sh abundance in the coastal areas of northern Hiroshima Bay.Moon jelly?sh were more abundant in the coastal areas of northern Hiroshima Bay,where the dissolved oxygen (DO)concentration was lower,while low in the central part of the bay.Japanese anchovy Engraulis japonicus eggs were most dominant (58.1%in number)among the ichthyoplankton and were abundant in the central area of Hiroshima Bay.Explanatory analysis was conducted to detect possible effects of environmental conditions on the abundance of moon jelly?sh and Japanese anchovy eggs during the summer months in Hiroshima Bay.Of the environmental conditions tested (temperature,salinity and DO of surface and bottom layers at each sampling station),bottom DO had the most signi?cant effect on the moon jelly?sh abundance:there was a negative correlation between the bottom DO and the moon jelly?sh abundance in Hiroshima Bay during summer.

1.Introduction

The moon jelly?sh Aurelia aurita is widely distributed throughout the coastal waters of the world and has been consid-ered as an important predator of zooplankton because of its high

consumption rates (Mo

¨ller,1984;Costello and Colin,1994).Increase in abundance of the moon jelly?sh,the same as other large gelat-inous zooplankton such as cnidarians and ctenophores,has occurred in estuarine and ocean ecosystems all over the world (Purcell and Arai,2001;Brodeur et al.,2002),potentially causing a signi?cant impact on smaller zooplankton and their predators in pelagic ecosystems (Uye and Ueta,2004;Haslob et al.,2007).In Japan,the moon jelly?sh is the most common jelly?sh species in coastal waters and its biomass has increased over recent decades

in Tokyo Bay (Toyokawa et al.,2000;Ishii,2001)and the Seto Inland Sea (Uye and Ueta,2004).Uye et al.(2003)observed moon jelly?sh aggregations of up to 250individuals m à2,which were estimated to consume nearly 100%of the mesozooplankton biomass during summer months in the coastal waters of the western part of the Seto Inland Sea.Clari?cation of the mechanism of moon jelly?sh blooms and effects of environmental conditions on moon jelly?sh abundance are indispensable for forecasting and regulation of moon jelly?sh blooms.However,much of the information available in the literature is of qualitative evaluations of moon jelly?sh distribution and its dynamics in nature.

The Seto Inland Sea is a semi-enclosed basin,which is sur-rounded by heavily urbanized areas with extensive industrial and agricultural development,and receives signi?cant freshwater from the surrounding watersheds (Ochi et al.,1978;Okaichi et al.,1996).Eutrophication of coastal waters has been common in Hiroshima Bay,the innermost part of the Seto Inland Sea (Okaichi et al.,1996).Nutritional input through the Ohta River,the northernmost part of

Hiroshima Bay,and estuarine circulation enhance both primary and secondary production in Hiroshima Bay(Hashimoto et al.,2006). Chlorophyll-a levels and therefore primary production of Hir-oshima Bay are among the highest of the nine bay areas of the Seto Inland Sea(from east to west:Kii Channel,Osaka Bay,Sea of Har-ima,Bisan Archipelago,Sea of Hiuchi,Bingo-Geiyo Archipelago,Sea of Aki including Hiroshima Bay,Sea of Iyo,Sea of Suo:Okaichi et al., 1996).During summer hypoxia prevails in the northern coastal areas of Hiroshima Bay,with dissolved oxygen(DO)concentrations of<2mg Là1(Okaichi et al.,1996,present study).Moderate decreases in DO to near hypoxic conditions(<3mg Là1),although not lethal during short-term exposure,can reduce the ability of larval?sh to escape and avoid predation and to capture prey (Breitburg et al.,1994).Recent laboratory experiments reported that bell contraction rate and predation rate on?sh larvae by moon jelly?sh under oxygen concentrations<2mg Là1were similar to those under higher oxygen concentrations(4–6mg Là1),indicating that moon jelly?sh are highly tolerant to low oxygen concentra-tions,as are several other jelly?sh species(Breitburg et al.,1994; Keister et al.,2000;Shoji et al.,2005;Thuesen et al.,2005).It has been suggested that a shift from size-selective to non-size-selective predation prevails in the predator–prey interaction and that rela-tive importance of trophic?ow from ichthyoplankton to moon jelly?sh increases during summer hypoxia in coastal waters(Shoji, 2008).Investigation of the abundance and distribution of moon jelly?sh in relation to environmental conditions is therefore important for understanding the effects of hypoxia on trophic?ow in plankton communities.

In the present study,biological and physical surveys were con-

ducted in the Hiroshima Bay in order to examine the effects of environmental conditions(temperature,salinity,and DO)on moon jelly?sh distribution.Pattern of the horizontal distribution and effects of the environmental conditions on moon jelly?sh were compared with the most dominant ichthyoplankton species,Japa-nese anchovy Engraulis japonicus in summer2006and2007.

2.Materials and methods

2.1.Field survey

Biological and physical surveys were conducted during monthly research cruises from July to September in2006and2007on the RV Aki,Fisheries and Marine Technology Center,Hiroshima Prefectural Technology Research Institute(HPTRI),in Hiroshima Bay(Fig.1). Moon jelly?sh were collected with a plankton net(0.45m in diameter,0.33mm in mesh aperture)with a?ow-meter at13 stations in Hiroshima Bay.A vertical haul with the plankton net from1m above the sea bottom to the surface was made at each station.Moon jelly?sh were sorted from the sample,identi?ed and measured for bell diameter(mm)and wet weight(g)on the boat. Ichthyoplankton samples were preserved in10%formalin.Vertical pro?les of temperature( C),salinity and dissolved oxygen(DO) concentration(mg Là1)were measured during each sampling event.

Jelly?sh and ichthyoplankton were enumerated as kg mà2and number mà2according to the?ow-meter counts.Of the total jelly?sh catch for the six cruises,the moon jelly?sh Aurelia aurita was most dominant,accounting for89.7%of the total wet weight (see the Results).Other jelly?sh species was excluded from the further analysis due to the small sample size.Ichthyoplankton were sorted and identi?ed to the lowest taxa possible.Eggs of Japanese anchovy Engraulis japonicus,the most dominant ichthyoplankton collected during the six cruises(58.1%in number of the total ich-thyoplankton,see the Results)were processed for analysis of seasonal change in abundance and horizontal distribution in Hir-oshima Bay.Other ichthyoplankton were excluded from the further analysis due to the small sample size.

Exploratory analysis was conducted in order to detect possible effects of the environmental factors on variability in the moon jelly?sh and Japanese anchovy egg abundance.Temperature, salinity and DO of surface and bottom layers at each sampling station were used as explanatory variables and abundance of moon jelly?sh and Japanese anchovy eggs as dependent variables.The environmental conditions(temperature,salinity and DO)and moon jelly?sh and Japanese anchovy egg abundance were compared between the two years by the use of Wilcoxon test.

3.Results

3.1.Environmental conditions

Mean sea surface temperature ranged between24.0 C(July) and26.8 C(August)in2006and between23.0 C(July)and28.9 C (August)in2007(Fig.2).There was a signi?cant inter-annual difference in the surface temperature in all months(Wilcoxon test, d.f.?1,July:P?0.004;August:P?0.0006;September: P<0.0001).The surface temperature was lower in northern Hir-oshima Bay during all cruises(Figs.3and4).

Mean surface salinity increased from20.8in July to28.1in September in2006and from27.8in July to31.8in September in 2007(Fig.2).In all months,surface salinity in2007was signi?-cantly higher than that in2006(Wilcoxon test,d.f.?1,July and September:P<0.0001;August:P?0.005).The surface salinity was lower in the northern part of Hiroshima Bay.

The mean bottom DO for all13stations ranged between 3.3mg Là1(September)and 5.0mg Là1(August)in2006and 3.3mg Là1(August)and4.7mg Là1(July)in2007(Fig.2).In

there was a signi?cant inter-annual difference in the DO (Wilcoxon test,d.f.?1,P ?0.003).The bottom DO was lower in the northern and/or eastern parts of Hiroshima Bay throughout the cruises.In September 2006and August and September 2007,some stations indicated a bottom DO of <2.0mg L à1(Figs.3and 4).3.2.Occurrence and distribution of moon jelly?sh

Of the total jelly?sh collected throughout the cruises,moon jelly?sh was most abundant,accounting for 89.7%in wet weight.Bolinopsis mikado and unidenti?ed jelly?sh species composed only 10.3%.The mean moon jelly?sh abundance was highest in July in both 2006(4.68kg m à2)and 2007(1.24kg m à2:Fig.2).The inter-year difference in the moon jelly?sh abundance was signi?cant in July (P ?0.014)and September (P ?0.013).There was no signi?cant difference in the bell diameter of moon jelly?sh between the two years (2006:177.6?32.2mm;2007:174.0?19.6mm).

Moon jelly?sh were more abundant in the northern part of Hiroshima Bay (Figs.3and 4).The areas of high abundance corre-sponded with those of low bottom DO.In July 2006and 2007,the highest moon jelly?sh abundance was observed in the eastern part of the bay,where bottom DO was lower than 2.0mg L à1.Moon jelly?sh were sparsely distributed in the central area of the bay throughout the cruises.

3.3.Occurrence and distribution of Japanese anchovy egg

A total of 654?sh eggs and 88larvae were collected during the six cruises.Japanese anchovy eggs were the most dominant,accounting for 65.9%in number of the total ?sh eggs.Japanese anchovy egg abundance was highest in August in 2006(276.3m à2)and in July in 2007(39.4m à2:Fig.2).There was a signi?cant difference in the Japanese anchovy egg abundance in August (P ?0.022)between the two years.

Japanese anchovy eggs were more abundant in the central or southernparts of Hiroshima Bay from July through September in 2006and in July in 2007while sparsely distributed in the coastal areas of the northern part of the bay throughout the six cruises (Figs.3and 4).3.4.Effect of environmental conditions on moon jelly?sh distribution

Of the environmental conditions tested,only bottom DO had a signi?cant effect on the moon jelly?sh abundance (F ?4.4758,P ?0.0379:all data combined).Moon jelly?sh were more abundant in the areas with lower levels of bottom DO (<3.0mg L à1).An exponential model was ?tted to the plots of moon jelly?sh abun-dance to bottom DO in July and September 2006(Fig.5).4.Discussion

4.1.Effect of dissolved oxygen concentration on moon jelly?sh Correspondence of high abundance of moon jelly?sh with the areas of moderate bottom-layer hypoxia (<3mg L à1)was observed in Hiroshima Bay during summer 2006and 2007.Previous laboratory experiments showed a high tolerance to low DO conditions (<2.0mg L à1)in moon jelly?sh:bell contract rate (an index of feeding activity)of the moon jelly?sh was constant over the DO levels tested (1.0–

5.8mg L à1:Shoji et al.,2005).Strong tolerance to low DO levels has also been observed in Aurelia labiata and sea nettle scyphomedusa Chrysaora quinque-cirrha under laboratory conditions (Breitburg et al.,1994;Thuesen et al.,2005)and high densities of the

ctenophore

Mnemiopsis leidyi in low DO concentrations in Chesapeake Bay (Keister et al.,2000).

Contrastingly,ichthyoplankton were less abundant in the northern part of Hiroshima Bay during the summer months.Swimming and/or feeding performance of major ?sh predators have been observed to signi?cantly decrease at DO lev-els <2.0mg L à1in coastal waters (juvenile striped bass Morone saxatilis ,adult naked goby Gobiosoma bosc and juvenile Spanish mackerel Scomberomorus niphonius :Breitburg et al.,1994;Shoji et al.,2005).Therefore,competition for prey and space between moon jelly?sh and ?sh weakens as DO decreases in coastal habitats.As a result,the relative importance of trophic ?ow from plankton to jelly?sh is considered to increase in coastal waters where summer hypoxia prevails (Breitburg et al.,1994;Shoji et al.,2005).We suggest that low DO conditions in the coastal waters of Hiroshima Bay during summer were favorable for moon jelly?sh feeding,growth and survival and resulted in the high abundance in the northern area.

4.2.Distribution of moon jelly?sh in Hiroshima Bay

In addition to the strong tolerance to low DO level,supply of young stages of moon jelly?sh and retention of them within the coastal areas of northern Hiroshima Bay should be included in the possible factors that explain the high moon jelly?sh abundance in this area.Hiroshima Bay is located at the most inner part and is the most enclosed area in the Seto Inland Sea (Okaichi et al.,1996).Moon jelly?sh polyps use arti?cial substrate such as concrete blocks,plastic ?oats and oyster beds (Yasuda,2003).In Hiroshima Bay,the natural shoreline has decreased to less than 40%of its original existence (Okaichi et al.,1996),with much of it replaced by concrete seawalls which are favorable for jelly?sh polyps.Intensive oyster culture in Hiroshima Bay (ca.50%of the total landings of oyster cultured in Japan)can provide suitable substrate for the moon jelly?sh polyps.We conclude that a combination of environ-mental factors such as available substrate for the polyps and high retention within the northern bay,in addition to their biological features (strong tolerance to low DO conditions),enhances the moon jelly?sh population in the northern part of Hiroshima Bay.

During most of the cruises,on the contrary,highest abun-dances of Japanese anchovy eggs were observed in the central part of Hiroshima Bay,where bottom DO was higher.The spatial difference in the Japanese anchovy abundance between the northern and central parts of the bay indicates that:(1)Japanese anchovy spawning was less intensive in and around the northern part of Hiroshima Bay,and/or (2)egg mortality was higher in northern part of Hiroshima Bay.It is likely that Japanese anchovy eggs were more vulnerable to predation by moon jelly?sh in

the

northern part of Hiroshima Bay where moon jelly?sh were abundant during summer2006and2007.Survival rates of bay anchovy Anchoa mitchilli eggs have been reported to markedly decrease at DO<3.0mg Là1(Chesney and Houde,1989)although there is no information on how low DO affects survival of Japa-nese anchovy eggs.In Chesapeake Bay,distribution of bay anchovy spawners was con?ned to the southern(near bay mouth) region when summer hypoxia prevailed in the northern(inner bay)region(Jung and Houde,2004).We conclude that the northern part of Hiroshima Bay was less favorable for Japanese anchovy spawning and/or egg survival due to low DO during summer2006and2007.

4.3.Inter-annual difference in moon jelly?sh abundance

Global warming and increase in temperature of shallow waters have been suggested to potentially enhance moon jelly-?sh blooms in coastal waters of Japan(Uye and Ueta,2004).In the present study,however,moon jelly?sh abundance was higher in2006,when the temperature was lower during late summer in Hiroshima Bay.Therefore,the inter-annual difference in moon jelly?sh abundance cannot be explained by tempera-ture condition alone,and other composite factors may better explain the higher moon jelly?sh abundance in2006in Hir-oshima Bay.

Among the environmental factors tested,difference in salinity was most signi?cant between the two years from July through September.The lower salinity in2006re?ects higher precipita-tion during summer,which might be favorable for growth and survival of moon jelly?sh.The total precipitation in Hiroshima City from January through July(1120.0mm)and from July through September(689.0mm)in2006was double the values in 2007(January through July:550.0mm;July through September: 345.5mm,Japan Meteorological Agency:http://www.jma.go.jp/ jma/).Higher freshwater?ow through the Ohta River,the northernmost part of Hiroshima Bay,increases primary and secondary production within the bay by enhancing the nutri-tional input and estuarine circulation(Hashimoto et al.,2006).In 2006,chlorophyll-a levels in the northern part of Hiroshima Bay were signi?cantly higher than in2007(Kawaguchi et al., unpublished data).Previous stomach contents analysis(Uye et al.,2003)and recent stable isotope analysis(Shoji et al., submitted for publication)showed copepods are the major prey source of moon jelly?sh in the Seto Inland Sea.Increase in freshwater?ow through the Ohta River should enhance growth and survival of moon jelly?sh in the northern part of Hiroshima Bay by increasing copepod production.We still lack ecological information on younger pelagic(ephyra)and benthic stages (polyp and strobila)of moon jelly?sh in nature.Further inves-tigation on the effect of variability in freshwater?ow through the Ohta River on primary and secondary production in Hir-oshima Bay in relation with growth and survival of moon jelly-?sh ephyra,polyp and strobila stages would help to clarify the mechanism of moon jelly?sh bloom,distribution and inter-year ?uctuation in Hiroshima Bay.Acknowledgements
