(5) Hormones in the thyroid gland play a role in the metabolism of carbohydrates in fish. Such glands in animals are sweat glands, breast glands, salivary glands, sebaceous glands, stomach, liver and pancreas. High concentrations of calcitonin are found in these glands of fish, but their specific function in the lower vertebrae is not known. They are carnivorous, e.g., Ophiocephalus (- Channa) punctatus. 1 0 obj When she failed to identify it, she sent its sketch to Professor J.L.B. .

However, the current study has found the opposite result. Fins are dorsal, pectoral, ventral, pelvic and caudal. Dorsal spine weakly serrated on its posterior edge; adipose fin base short, about as long as the rayed dorsal fin base. Adult male and female fishes migrate from river to sea where they lay eggs and die. Manage Settings Neurosecretory cells are large nerve cells that contain basophilic cytoplasm and polymorphic nuclei.

The endocrine glands usually control the long-term activity of the target organ and control various physiological processes such as digestion, metabolism, growth, development, reproduction, etc. . It is usually located in the posterior part of the kidney and is thought to be an endocrine organ. It is also called rostral pars distalis. Skin has rudimentary scales. Color is brownish-gray on back, silvery on flanks and belly. Moreover, their positions vary. They feed and grow in sea for 2 or 3 years, then enter the river and undergo metamorphosis to become adults. In some teleosts such as Phoxinus, Rutilus and Astyanax, thyrotrophs aldehydes are used to stain fuchsin (AF). It feeds on plankton and decayed vegetables.
