emeritus professor of ophthalmology at the UIC College of Medicine in Chicago, to investigate how zinc may control the wily glutamate. Using the retina of the skate, a cartilaginous fish resembling a manta ray, they record electroretinograms (ERGs) to measure how retinal neurons respond to light stimuli in the presence and absence of normal levels of zinc. Their preliminary results indicate that ionic zinc (Zn2+) is co-released with glutamate from skate rods, and feeds back onto the photoreceptor terminals to suppress the release of glutamate, thus providing an automatic gain control mechanism that reduces the risk of glutamate toxicity.

Demonstrating the role of Zn2+ in the regulation of glutamate release from skate rods is still a long way from fully understanding its potential use in therapy for human diseases where glutamate toxicity may be involved, but its ubiquity among vertebrates shows promise. The presence of available Zn2+ and/or its transporters has been observed in the photoreceptor region of salamanders, zebrafish, mice, and skates, but "The question is whether this is an integral part of the physiology of the retina," says Ripps. "Once you understand the normal retina, you can determine the basis of retinal disorders."

Managing the Conch Fishery

Massachusetts fisherman once considered the New England whelk or "conch" as nothing more than bycatch. Although demand existed for the large-shelled snail, traditionally used for cooking in East Asian cultures, it could more easily be trawled in the waters around South America, the Caribbean and Asia, making conch unprofitable in the Northeast. This turned around in the 1980s, however, when overfishing of whelk quickly transformed the small New England conch fishery into a multi-million dollar industry.

To maintain local conch populations, the Massachusetts Division of Marine Fisheries issued regulations in 1992 on how much whelk could be harvested. These include
