Die size of the stock and their fatness declined dramatically in 1983 because of the outbreak of the medusa Aurelia aurita, which prospered on the enhanced level of zooplankton and competed with the sprat for food. Surprisingly, the sprat stock overcame the pressure from Aurelia the following year, and its fatness increased. Two years after that the medusae declined in numbers and the sprat stock increased dramatically. This reduced the food supply - and so the fatness of the stock declined. Die sprats grew fat again only when their numbers dropped in 1988. The food factor therefore influenced both the accumulation of energy and reproduction in the stock. 

Indices of condition like those mentioned above have also been used in studies of other water organisms. The food available to the medusa Aurelia aurita and the ctenophore Mnemiopsis leidyi can be judged from their level of carbohydrates (Anninsky, 1990), and that available to copepods such as Calanus helgolandicus can be judged from their content of neutral lipids, especially wax esters (Yuneva and Svetlichny, 1996).

Water-soluble fractions containing 54 were isolated from two species of jellyfish, Aurelia aurita and Carybdea rastonii. Besides arsenobetaine 54 (the major arsenic compound), the tetramethylarsonium ion 53 and arsenocholine 55 were also detected [151, 152]. Nine species of jellyfish, including the two species treated in the previous paper [151], were classified into arsenocholine-rich and arsenocholine-poor species.

Taken from the jellyfish Aurelia aurita harvested in the North Sea, the species Epicoccumpurpurascens produces in culture a long-chain mannoside with a tetramic acid, epicoccamide. However, this original, and most probably amphiphilic, derivative has no detectable biological activity...
