Immunohistochemical study of pituitary cells in wild and captive Salminus hilarii (Characiformes: Characidae) females during the annual reproductive cycle
Freshwater fish that live exclusively in rivers are at particular risk from fragmentation of the aquatic system, mainly the species that migrate upriver for reproduction. That is the case of Salminus hilarii, an important migratory species currently classified as "almost threatened" in the São Paulo State (Brazil), facing water pollution, dam construction, riparian habitat destruction and envir...
متن کاملPattern of Sex Steroid Concentrations in Relation to the Annual Reproductive Cycle of Wild and Captive Black Rockfish
—Gonadal development and plasma steroid hormone concentrations of wild (N1⁄4 73) and captive (N1⁄465) black rockfish Sebastes melanops were examined over 1 year. Seasonal variation was observed in the concentrations of testosterone and estradiol in the plasma of wild female black rockfish, the highest concentrations of each occurring in October. Male black rockfish exhibited the highest testost...
متن کاملGonadal changes and serum steriod levels during the annual reproductive cycle of the pearl oyster Pinctada fucata gould
The annual reproductive cycle of peal oyster Pinctada fucata was characteised by documenting gonadal development and changes in serum levels of estradiol-17b (E2), testosterone (T) and progesterone (P) in the wild bivalve caught in natural beds in the Persian Gulf throughout the year. Bivalve populations employed in this study spawn in June-July and November-December. The pearl oysters had grou...

With the aim of creating an inventory of the metazoan gill parasites of Salminus hilarii in the Taquari River, state of São Paulo, Brazil, five species of monogeneans (Anacanthorus contortus, A. bicuspidatus, Annulotrematoides parisellei, Jainus iocensis and Tereancistrum arcuatus) are reported the first time for this host. A total of 28 fish were sampled quarterly between April 2011 and Januar...
