Circulatory physiology and erythropoiesis in freshwater fish Labeo rohita experimentally parasitized by Argulus bengalensis

AbstractA new species of myxozoan (Myxozoa: Bivalvulida) Thelohanellus habibpuri sp. n. parasitic in tropical freshwater fish collected from the Habibpur, West Bengal, India is described in this paper. T. habibpuri was found in the Pectoral fin of Labeo rohita (Hamilton-Buchanan, 1882). The diagnostic characters of T. habibpuri are: generally oval milky-whitish plasmodia attached in the pectoral fin of host fishes; spore egg-shaped to ovoid with slightly tapering anterior and rounded posterior end, averaging 13.9 × 8.5 μm in size; a single oval-round polar capsule 6.0 × 4.9 μm in diameter, with polar filament wound in 3-4 coils. Finely granular sporoplasm containing two slightly oval nuclei (1.4 μm in diameter) and a small iodinophilous vacuole (3.0 μm in diameter) present in the spore.SEM study of this myxozoan reveals the anterior extremity of spore is truncated. The Cnidocyst discharge channel appear as a dark area. The longitudinal wavy surface are visible on the spore.

Texture Attributes

Freshwater fish, rohu ( Labeo rohita) curry was prepared in a north Indian style, packed in polyestercoated tin free steel (TFS) cans in a 60:40 ratio (fish:curry) and thermal processed in a retort. Physical tests of the can such as double seam efficiency, lacquer integrity, sulphur resistance and food contact application showed that polyester-coated TFS cans can be used for canning fish products. F0 value of the product was 8.79 when the thermal processing was at 121°C for 46.42min, and cook value to achieve tenderness of the product was 102min. The processed product was found to be commercially sterile. The product was acceptable even after 6 months of storage at room temperature (28±2°C) and at 37°C with regard to all sensory attributes. Texture attributes such as hardness, chewiness, springiness and cohesiveness did not show marked variation in the samples stored at room temperature and at 37°C. There were no significant changes in chemical parameters during the storage period. The results showed that the polyester-coated TFS cans can be used for processing ready to serve fish products, which can be stored at room temperature for long periods.
