The Pituitary Gland of a Catfish, Clarias batrachus

Morphological and histological studies on the pituitary gland of Liza carinata from the Suez Bay (Red Sea, Egypt), with special reference to the gonadotrophs

“…The acidophils (A2) of L. carinata are found mainly in the dorsal region and occasionally in middle region of the meso-adenohypophysis, while the basophils (B1) are found in the middle region of the meso-adenohypophysis and the basophils (B2) are found in the peripheral zone of the meso-adenohypophysis. These results are in accordance with those of Lehri (1966) in Clarias batrachus, Rizkalla (1976) in Mugil auratus, and Ramadan et al (1988) in Sparus aurata.…”

Evaluation of biofilm of Aeromonas hydrophila for oral vaccination of Clarias batrachus—a carnivore model

“…Therefore, the current study was conducted in order to evaluate the performance of the biofilm vaccine in a carnivorous fish model, C. batrachus. Dietary habits of the catfish have been described as predator but not piscivore [23], scavenger [24], omnivore [25], insectivore [26], larvivore [27], with great affinity for a carnivorous diet [28]. More or less it shows preference for food of animal origin and possesses a well-demarcated stomach unlike carp.…”

Course of neurosecretory tracts within hypothalamus in a snow trout,Schizothorax niger (Heckel) byin situ technique

“…The presence of distinct VMT as seen in S. niger is also reported in other Cyprinids -L. cephalus, A. brama and P. phoxinus by Jasinski et al (1974);and differs from the VMT or extramedian tracts of C. batrachus (Sathyanesan 1969) and H. fossilis (Vishwanathan and Sunderaraj 1975) where certain number of well isolated and compact lateral tracts are given from the main tract. Lehri (1966), reported that presence of VMT or extramedian neurosecretory tracts of catfishes may be a devise to increase storing and release capacity. This may hold good for S. niger also where a net work of fibres is formed just above the pituitary stalk.…”
