“…Food chains involving jellyfish are poorly understood (Mills, 2001); intervening by allowing so much plastic to enter the oceans seems unwise. A hopeful sign is that some cities, communities, and individuals are restricting their use of plastic bags.…”

a b s t r a c tThe leatherback, Dermochelys coriacea, is a large sea turtle that feeds primarily on jellyfish. Floating plastic garbage could be mistaken for such prey. Autopsy records of 408 leatherback turtles, spanning 123 years , were studied for the presence or absence of plastic in the GI tract. Plastic was reported in 34% of these cases. If only cases from our first report (1968) of plastic were considered, the figure was 37%. Blockage of the gut by plastic was mentioned in some accounts. These findings are discussed in the context of removal of top predators from poorly understood food chains.

“…A. aurita (Linnaeus, 1758) A. aurita is distributed worldwide in coastal waters and is associated with a wide range of water temperatures (0-36°C) and salinities (3-36‰) (Arai, 1997;Martin, 1999). The cases of A. aurita blooms have been reported in many coastal areas, including the Baltic region, Japan, Korea, India and Australia (Mills, 2001). In Chinese seas, the aggregation and blooms of A. aurita were mainly observed in harbors and inshore areas in the temperate region including Yellow Sea and Bohai Sea ( Fig.…”

“…There have been very few studies on the cause of A. aurita blooms in China. However, previous case studies in other countries indicated that coastal eutrophication could be an important contributor to the A. aurita blooms (Arai, 2001;Mills, 2001). The increased nutrients in coastal waters can significantly increase phytoplankton biomass which could support the food source of jellyfish (e.g., zooplankton).…”

“…Eutrophication is considered to be one of important factors contributing to increased jellyfish abundance and blooms (Mills, 2001;Diaz and Rosenberg, 2008). The excessive nutrients led to a high biomass of phytoplankton which can support polyp and medusa stage jellyfish.…”

“…Over the last decade, a significant increase in jellyfish blooms has been observed worldwide in marine ecosystems and are becoming seen as an indicator of a state shift in pelagic ecosystems (Arai, 2001;Graham et al, 2001;Mills, 2001;Purcell, 2005;Purcell et al, 2007;Uye, 2008;Zhang et al, 2009;Richardson et al, 2009). Distinguished from the natural phenomena of jellyfish aggregation, jellyfish blooms in pelagic ecosystems are regarded as a response to anthropogenic disturbance and climate change and can cause numerous deleterious consequences for industry and the community, such as, reduced fishery production from the competition for food with fish, stinging of swimmers by venomous species and clogging coastal power plant cooling water intakes (Purcell et al, 2007;Richardson et al, 2009).…”

1. Marine aquaculture relies on coastal habitats that will be affected by climate change. This review assesses current knowledge of the threats and opportunities of climate change for aquaculture in the UK and Ireland, focusing on the most commonly farmed species, blue mussels (Mytilus edulis) and Atlantic salmon (Salmo salar). 2. There is sparse evidence to indicate that climate change is affecting aquaculture in the UK and Ireland. Impacts to date have been difficult to discern from natural environmental variability, and the pace of technological development in aquaculture overshadows effects of climatic change. However, this review of broader aquaculture literature and the likely effects of climate change suggests that over the next century, climate change has the potential to directly impact the industry. 3. Impacts are related to the industry's dependence on the marine environment for suitable biophysical conditions. For instance, changes in the frequency and strength of storms pose a risk to infrastructure, such as salmon cages. Sea-level rise will shift shoreline morphology, reducing the areal extent of some habitats that are suitable for the industry. Changes in rainfall patterns will increase the turbidity and nutrient loading of rivers, potentially triggering harmful algal blooms and negatively affecting bivalve farming. In addition, ocean acidification may disrupt the early developmental stages of shellfish. 4. Some of the most damaging but least predictable effects of climate change relate to the emergence, translocation and virulence of diseases, parasites and pathogens, although parasites and diseases in finfish aquaculture may be controlled through intervention. The spread of nuisance and non-native species is also potentially damaging. 5. Rising temperatures may create the opportunity to rear warmer water species in theUKand Ireland. Market forces, rather than technical feasibility, are likely to determine whether existing farmed species are displaced by new ones
