The Young Stages of the Cannonball Jellyfish (Stomolophus sp. 2) from the Central Gulf of California (Mexico)

Diversity, 2021
Exploitation of the cannonball jellyfish (Stomolophus sp. 2) is increasing in Mexico and USA due to successful fisheries associated with seasonal blooms in coastal areas. Previously, it was proposed that such blooms could be identified by recognizing the

Preface: Jellyfish blooms: interactions with humans and fisheries [PDF]

Hydrobiologia, 2012
There is a general impression that jellyfish and other gelatinous organisms are increasing in number. Media, TV, and newspapers contribute to this impression. So are increases in jelly populations real, or is this phenomenon just a biased perception?

Murder in the dark: Can parasites bring jellyfish blooms to fall?

Fauna Norvegica
Jellyfish form irregular and seemingly unpredictable blooms that can be the result of redistribution/aggregation events or peaks in population growth. Such blooms can affect ecosystem structure and stability due to the role of jellyfish as top predators

Jellyfish Stings Trigger Gill Disorders and Increased Mortality in Farmed Sparus aurata (Linnaeus, 1758) in the Mediterranean Sea.

PLoS ONE, 2016
Jellyfish are of particular concern for marine finfish aquaculture. In recent years repeated mass mortality episodes of farmed fish were caused by blooms of gelatinous cnidarian stingers, as a consequence of a wide range of hemolytic, cytotoxic, and ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Identification and population genetic analysis of jellyfish blooms in Trondheimsfjord Role of polyps in jellyfish populations connectivity [PDF]

, 2021
There is a strong need to utilize jellyfish biomass in both economic and ecological way. These two aspects rely on the capability of jellyfish to bloom in large quantities and on accurate prediction on where and when jellyfish blooms will most likely ...
