Abstract

Fish, as poikilotherms, are subjected to the influence of the environmental temperature. It has been already reported that fish immune system is influenced by temperature; however, no information is available concerning if temperature has any effect on thrombocytes. Thrombocytes from fish reared at 6°C, 10°C and 20°C were assessed for alteration in their aggregation capacity. Thrombocyte percentages were altered by the water temperature at which the fish was reared, decreasing from 19% (at 10°C) to 13% (at 6°C) and increasing to 24% (at 20°C). However, the aggregation capacity was not significantly compromised by these temperature changes in an individual cell basis, which would suggest a capability of this cell, to maintain this indispensable function at different temperatures.
