A Survey on Different Methods Fish Fixation in Resin and the Effect of Different Doses of Hardener in this Method

In this study, Polyester Resin was used as a fixing material for fixing aquatics samples for education uses and that have advantages such as not having stink, anti-Carcinogen, stability of color, easy transportation and more durable than actual common methods which are used to keep samples in Formalin solution. Hence, first proper dosage of a stiffener that must be mixed with Resin was Resin and finally they compared three methods by using scoring to the most important factors which can be significant in stabilization of sample.In the first method, fresh fish was used in Resin which can be utilized just for small fish. In the second method, Formalin was used before putting samples in Resin, but achieved results show a kind of blurring in samples.In the third method, acetone was used as an absorbing material after stabilization of samples by Formalin that has better results rather that former two of hers methods that prepares samples with higher clearance and lower blurring and being more homogeneous compared to her two former methods.
