Lactate formation in callianassa californiensis and upogebia pugettensis crustacea thalassinidea


, : Lactate formation in callianassa californiensis and upogebia pugettensis crustacea thalassinidea. Marine Biology (Berlin) 50(3): 249-254

The ability to accumulate lactate as a result of laboratory exposure to anoxia was examined in 2 spp. of mud-dwelling shrimp, the ghost shrimp C. californiensis and the mud shrimp U. pugettensis. Hemolymph lactate accumulated to a much greater degree in the mud shrimp, even though the overall levels of lactate dehydrogenase activity were similar in tissues of the 2 shrimps. Carbohydrate reserves, estimated as glycogen, were not significantly depleted in muscle or midgut gland of either species as a result of anoxic stress. Possible metabolic strategies employed to cope with the hypoxic environment of these crustaceans are discussed.

The paper notes that past studies on art investment generally have found that returns are low and risk is high; but suggests in this study that the return to art investment is more in line with traditional investments and thus the cost for consump...
