Jellyfish are one of the most conspicuous animals in our oceans and are renowned for their propensity to form spectacular blooms. The unique features of the biology and ecology of jellyfish that enable them to bloom also make them successful invasive species and, in a few places around the world, jellyfish have become problematic. As man increasingly populates the world’s coastlines, interactions between humans and jellyfish are rising, often to the detriment of coastal-based industries such as tourism, fishing and power generation. However we must not lose sight of the fact that jellyfish have been forming blooms in the oceans for at least 500 million years, and are an essential component of normal, healthy ocean ecosystems. Here many of the world’s leading jellyfish experts explore the science behind jellyfish blooms. We examine the unique features of jellyfish biology and ecology that cause populations to ‘bloom and bust’, and, using case studies, we show why jellyfish are important to coastal and ocean ecosystem function. We outline strategies coastal managers can use to mitigate the effects of blooms on coastal industries thereby enabling humans to coexist with these fascinating creatures. Finally we highlight how jellyfish benefit society; providing us with food and one of the most biomedically-important compounds discovered in the 20th century. .

Jellyfish form spectacular population blooms and there is compelling evidence that jellyfish blooms are becoming more frequent and widespread. Blooms have enormous ecological, economic, and social impacts. For example, they have been implicated in the decline of commercial fisheries, they block the cooling water intakes of coastal industries and ships, and reduce the amenity of coastal waters for tourists. Blooms may be caused by overfishing, climate change, and coastal pollution, which all affect coastal waters around the world. Jellyfish Blooms: Causes, Consequences and Recent Advances presents reviews and original research articles written by the world’s leading experts on jellyfish. Topics covered include the evolution of jellyfish blooms, the impacts of climate change on jellyfish populations, advances in acoustic and molecular methods used to study jellyfish, the role of jellyfish in food webs and nutrient cycles, and the ecology of the benthic stages of the jellyfish life history. This is a valuable resource for students and professional marine biologists, fisheries scientists, oceanographers, and researchers of climate change.

Jellyfish generally are considered to be nuisances because they interfere with human activities by stinging swimmers, clogging power plant intakes and nets of fishermen, killing fish in aquaculture pens, and being both predators and competitors of fish. There is concern that environmental changes such as global warming, eutrophication, over-fishing, and coastal construction may benefit jellyfish populations. During this past decade following the first Jellyfish Blooms volume, some species have bloomed more frequently, expanded their range, and caused more problems for humans. Mnemiopsis leidyi, the ctenophore that invaded the Black Sea in the 1980s and damaged fisheries, now also blooms in the North, Baltic, and Mediterranean seas. Nemopilema nomurai, a giant Asian jellyfish, has bloomed frequently during this decade, causing severe damage to the Japanese fishing industry. Jellyfish Blooms: Interactions with Humans and Fisheries is the fourth volume in this series. Syntheses and original research articles address the question if jellyfish have increased globally and what factors may have contributed to the abundance of jellyfish. This volume is the most extensive to date, containing papers from all continents (except Antarctica) on scyphozoans, hydrozoans, cubozoans, staurozoans, and ctenophores, and on the fate of jellyfish blooms. This is a key reference for students and professional marine biologists, oceanographers, and fishery scientists and managers.Previously published in Hydrobiologia, vol. 690, 2012 Previously published in Hydrobiologia, vol. 690, 2012.
