Abstract
Histological structure of the fish cannot be separated from its morphology. Morphology of fish associates with its habitat like Gurame, Goldfish, and Tilapia which have different morphologies In general, the skin is composed of three layers of the epidermis, dermis and hypodermis, eventhough there are differences in thickness, due to different habitats. This study aims to determine the thickness differences in the histological structure of Gurame, Goldfish and Tilapia fish as an alternative tanning material.
The materials used are Gurame, Goldfish and Tilapia skins, with three pieces per each and taken randomly. Each layer of skins, especially from the abdomen and croupon parts, was made into histological preparations. Histological preparations were examined using a microscope and measured its thickness in the epidermis, the papilare stratum and the reticular stratum. This study used Complete Randomized Design to analyze the data. The average epidermis thickness of the abdomen is Gurame: 53.33 mμ; Goldfish: 23.97 mμ and Tilapia: 15.67 mμ. The epidermis of croupon is Gurame: 17.73 mμ; Goldfish: 9.73 mμ and Tilapia: 13.33 mμ. The Thickness of the papilare stratum of the abdomen is Gurame: 70 mμ; Goldfish: 212.67 mμ and Tilapia: 111.67 mμ. The papilare stratum of croupon is Gurame: 307 mμ; Goldfish: 111.67 mμ and Tilapia: 357.67 mμ; and the thickness of the reticular stratum of the abdomen is Gurame: 583.67 mμ; Goldfish: 565.33 mμ and Tilapia: 574.37 mμ. The reticular stratum of croupon is Gurame: 572.70 mμ; Goldfish: 544.67 mμ and Tilapia: 384.00 mμ. The results of the analysis showed that there is no difference in the epidermis thickness of the three different skin types and there is a real difference in papilare and reticular stratums. From the histological structure, the three types of skins can be used as raw tanning materials.
