Abstract

The eye structures and chemical details of the retinal layer in juvenile Queen Danio—Devario regina, an ornamental fish—were histologically investigated under a light microscope. Sample fish were collected from the Tapee River, Nakhon Si Thammarat province, Thailand and their heads were exclusively prepared using a standard histological technique. The results revealed that the eye of D. regina was composed of three layers—inner, middle and external—based on histological organization and cell types. The inner layer was composed of 10 layers; 1) pigment epithelium, 2) photoreceptor layer, 3) outer liming membrane, 4) outer nuclear layer, 5) outer plexiform layer, 6) inner nuclear layer, 7) inner plexiform layer, 8) ganglion cell layer, 9) optic nerve layer and 10) inner limiting membrane, respectively. The localization and chemical details showed that a periodic acid-Schiff reaction for the detection of glycoprotein was intensive in the pigment epithelial layer whereas the inner plexifrom layer had only a slight reaction. Reaction of aniline blue was employed for the detection of mucopolysaccharide which was slightly positive for three layers—the outer limiting membrane, outer plexiform and inner plexiform.

Abstract

The first investigations of the thyroid gland and interrenal tissue with reference to the endocrine parenchyma of short mackerel Rastrelliger brachysoma were subjected to histological analysis. Specimens were collected during the fishing season (October to November 2013) from the Upper Gulf of Thailand. Under a light microscope, the thyroid gland of R. brachysoma was distinctly found located within the branchial region. Within this gland, it consists of several follicles among afferent brachial arteries. Each follicle exclusively contained a colloid that was surrounded by a simple, cuboidal, follicle epithelium. Histological study showed that the localization of interrenal tissue was in the anterior kidney. This tissue was composed of two parts based on the structural compositions and cell types; (i) the stromal compartment was constituted of various interrenal cells and (ii) the interstitial compartment contained the connective tissue, leucocytes and blood sinuses, with reference to the lymphatic tissue.

Abstract

The histology of the organization of the eye in the Stoliczkae's barb Puntius stoliczkanus was investigated using a light microscope. It was found that the eye in P. stoliczkanus comprised three layers—external, middle uveal and inner. The external layer consisted of the cornea and sclera. The cornea showed three layers: 1) corneal epithelium, 2) corneal stroma and 3) corneal endothelium, while the sclera exhibited a thick connective fi ber and an external sheath of hyaline cartilage supporting the sclera. The middle uveal layer showed only the lens and choroid. The lens protruded into the aqueous chamber. The choroid was subdivided into two distinct layers: 1) a connective layer adjacent to the sclera and 2) the lamina vasculosa and choriocapillaris. The inner layer or retinal tunica was composed of 10 distinct layers: 1) pigment epithelium, 2) photoreceptor layer, 3) outer liming membrane, 4) outer nuclear layer, 5) outer plexiform layer, 6) inner nuclear layer, 7) inner plexiform layer, 8) ganglion cell layer, 9) optic nerve layer and 10) inner limiting membrane, respectively, from the outside inward. These results provided data for other investigations in aquaculture, reproductive biology and histopathology. Keywords: eye, histology, Puntius stoliczkanus, Tapee river, Thailand
