Abstract:
The effect of the preserver on the length‐weight relationship and condition factor were estimated using 50 specimens of Tlaloc labialis; a small stream fish from the Grijalva River basin, México. They were measured at different stages of preservation: freshly collected, fixed in 10% formalin and preserved in 70% ethanol for over a 2 years period. All fish decreased in weight and condition factor, with very significant differences compared to the fresh material. The value of the coefficient (b) increased and stabilized from the second month of preservation in ethanol.
