Abstract
In the current research, fish and their internal organs are preserved through different new
techniques rather than traditional method in fisheries, such as sheet plastination, glycerine
mount technique, and Alizarin red stain technique. These new techniques are already
implemented in various medical disciplinaries like Medical sciences and Veterinary science.
This kind of preservation in fisheries is innovative for ichthyotaxonomy. These techniques
can preserve the specimen for prolonged duration.
In current research for sheet plastination, thin section of fish sample (3-4 mm) is preserved
by following steps: fixation, dehydration, impregnated (EP), curing to preserve. By using
commercial resin polymer this technique becomes inexpensive as compared to the standard
plastination techniques.
In the present study fish internal organ is preserved by glycerine mount technique by
using following steps, fixation, dehydration, impregnation (glycerine), curing. This
technique is inexpensive. Delicate internal organs can be preserved through this method for
prolonged lifespan, various internal organs can be identified clearly.
In Alizarin technique the skeletal system of fish is preserved by using stain called
Alizarin red which stain the bones of fish without removing muscles and then stored in pure
glycerine for long period of time. This method is useful for identification in skeletal
deformities and ossification in different bones according to concentration of stain taken by
different bones.
