A seasonal study of the seminal vesicles in relation to that of the testes had been conducted in the catfish, H. fossilis. The annual reproductive cycle of the catfish has been divided into (i) Preparatory period (February–April), (ii) Prespawning period (May–June), (iii) Spawning period (July–August) and (iv) Postspawning period (September–January). Testes exhibit initiation of spermatogenesis in the mid‐preparatory period, but significant increase in weight of the testes accompanied by active… Expand
Seasonal effects of pinealectomy on testicular recrudescence and secretory activity of seminal vesicles in the catfish Heteropneustes fossilis (Bloch)
TLDR
The findings suggest that the role of the pineal in catfish reproduction is variable and depends upon the photoperiod and temperature regimes to which the fish are exposed, as well as on the time of the year and the state of the reproductive cycle. Expand
Histological structure of the male reproductive organs and spermatogenesis in a copulating sculpin, Radulinopsis taranetzi (Scorpaeniformes: Cottidae)
TLDR
Investigation of the structure and function of male reproductive organs in the copulating sculpin Radulinopsis taranetzi found that the fluid is secreted and spermatozoa are stored in the seminal vesicles during February to July, which is presumably when mating occurs. Expand
THE NATURAL GONADAL CYCLE IN THE AFRICAN CATFISH CLARIAS GARIEPINUS; A BASIS FOR APPLIED STUDIES ON ITS REPRODUCTION IN FISH FARMS
TLDR
Fish from the Buteiha area of Lake Kinneret, collected from November until January, preceded those from the Hula region in gametogenesis and 3β-HSD activity, probably due to the higher water temperature in the lake. Expand
A comparison of steroid profiles in the testis and seminal vesicle of the catfish (Heteropneustes fossilis).
TLDR
High levels of corticosteroid profile in the testis and SV is shown, which may be helpful in monitoring reproductive capability and important for fish breeding in captivity. Expand
Annual cyclic variations in some biochemical constituents of seminal vesicle and testis of the catfish Heteropneustes fossilis (Bloch): a study correlating plasma testosterone level.
TLDR
There is an inverse relationship between the annual patterns of fructose and glucose with fructose dominant in the prespawning and early spawning phases (June-July), and glucose in the resting phase (November-January). Expand
Annual Correlative Changes in Some Biochemical Contents of Seminal Vesicle and Testis in the Catfish Clarias batrachus (L)
TLDR
The similarities in the annual distribution of various biochemical correlates, and the presence of interstitial cells and scattered spermatogenic cysts suggest that the SV has a common origin with the testis and is specialized for secreting a glyco-lipoprotein-rich substance for temporary storage of the sperm.

Histological and ultrastructural characteristics of the testis of the invasive suckermouth sailfin catfish Pterygoplichthys disjunctivus (Siluriformes: loricariidae) from Marikina River, Philippines.
TLDR
The histological and ultrastructural features of the testis of the invasive suckermouth sailfin catfish Pterygoplichthys disjunctivus rapidly proliferating in Marikina River, Philippines were characterized during the fish's 2010-2011 reproductive season to describe the gonad dynamics and reproduction.

Reproduction of the catfish Iheringichthys labrosus (Lütken) (Pisces, Siluriformes) in Furnas reservoir, Minas Gerais, Brazil
TLDR
The variations of the stomach repletion index, coelomic fat and condition factor indicated that the feeding activity was reduced and that the energetic reserves were consumed during the reproductive period. Expand
Effect of Extirpation of "Seminal Vesicles" on the Reproductive Performance of the Male Catfish, Heteropneustes fossilis (Bloch)
TLDR
In teleosts the sex accessory glands attached to the base of the testes are generally called "seminal vesicles," even though they are not derivatives of the Wolffian duct (Weisel 1949). Expand
A Histological Study of the Seminal Vesicle of the Armoured Catfish Corydoras aeneus
TLDR
Considering the reproductive behaviour of C. aeneus, it is believed that the protection associated with the immobilization of the sperm cells assures the sperm integrity during the passage through female's intestine until fertilization. Expand

The Seminal Vesicles and Their Seasonal Changes in the Indian Catfish, Heteropneustes
TLDR
The seminal vesicles were observed in the male Heteropneustes in connection with the studies on the correlation between the structure of the pituitary gland and the sea-sonal changes in the testes (Sundararaj, 1958). Expand
The Seminal Vesicles and Testes of Gillichthys, a Marine Teleost
TLDR
The male mudsucker, Gillichthys mirabilis, has well developed accessory sex organs and is common in the bays and estuaries along the Pacific coast of the United States, the testes and vesicles have not been previously described. Expand
Effects of exogenous gonadotrophins and gonadal hormones on the testes and seminal vesicles of hypophysectomized catfish, Heteropneustes fossilis (bloch).
TLDR
While TP or HCG can reinitiate and restore spermatogenesis in the testes and secretory activity in the seminal vesicles of hypophysectomized catfish, FSH singly is virtually ineffective although it can synergize with HCG. Expand
CYCLICAL CHANGES IN THE TESTICULAR ACTIVITY OF THE LAKE CHUB, COUESIUS PLUMBEUS (AGASSIZ)
The cyclical changes in the activity of the testes of a teleost, the lake chub, from a north temperate latitude have been studied by histological and histochemical methods with a quantitativeExpand
Seminal vesicle' response of intact, castrate, and hypophysectomized catfish, Heteropneustes fossilis (Bloch), to testosterone propionate, prolactin, and growth hormone.
TLDR
Treatment with all the three hormones at the same time resulted in marked synergism in stimulating the seminal vesicles of the catfish, Heteropneustes fossilis, and maximum response was observed after simultaneous administration of TP, LtH, and STH. Expand
Effect of prolactin on the “seminal vesicles” and neural regulation of prolactin secretion in the catfish Heteropneustes fossilis (Bloch)
TLDR
The results indicate that the neural control of prolactin secretion in the catfish is presumably accomplished by an inhibitory mechanism similar to that demonstrated in the mammals. Expand
Correlation between the structure of the pituitary and the changes in the testes of the indian catfish heteropneustes
TLDR
The present investigation was undertaken to ascertain whether or not the structural changes of t he pituitary are correlated with the seasonal changes in the testes of Heteropneustes fossilis (Bloch). Expand
The Reproductive Cycle of the Three-Spined Stickleback, Gasterosteus aculeatus, Linn
TLDR
The migration of the fish which occurs in connection with reproduction was examined to ascertain whether it bears a relation to the reproductive cycle, and the relation between the development of these and the changes in the testis was investigated in detail. Expand
Accessory glands and their ducts in the reproductive system of the male toadfish, Opsanus tau
TLDR
The accessory genital glands ofOpsanus tau are large fan-shaped organs lying in the posterior region of the abdominal cavity that drain into the paired spermatic ducts as they course posteriorly to exit into the cloaca via a grooved genital papilla. Expand
