FISH GILL IONIC TRANSPORT: METHODS AND MODELS

Abstract
It should be obvious from this rather cursory review that substantial strides have been made in the elucidation of the transport parameters of the fish gill, due in no small part to the use of various "pieces" of the whole animal. To a considerable extent the techniques have been complementary with data from one system corroborating, but expanding, data from another system. However, each of the approaches has its advantages and disadvantages, which must be appreciated and accounted for. It is also obvious that, per usual, the number of species of fishes which have been examined is vanishingly small, and no single species has been examined utilizing all of the techniques described in this review. It is therefore appropriate to suggest that more species should be examined and that more investigators should use a variety of techniques, rather than a single method of approach.
