1. The effect of thiocyanate on chloride and sodium fluxes across the gill was studied in the goldfish Carassius auratus. At low external chloride concentrations, addition of SCN- to the bathing solution markedly inhibited chloride influx and efflux, the net flux being reversed, SCN- injection was without effect. SCN- had no effect on sodium fluxes when injected or added to the external medium....

Fresh water fish, such as carp (Cyprinus carpio), koi koki (Carassius auratus) and comet auratus have great opportunities for developing aquaculture in Indonesia. However, the presence of argulosis disease caused by ectoparasites Argulus sp. be one obstacles. This parasitic infestation can cause fish to experience a decrease body weight, weakness, bleeding, secondary infection, sale value even ...

Histochemical and ultrastructural studies of gonads from goldfish Carassius auratus and several species of salmon (genus Oncorhynchus) indicate that the Leydig or interstitial cells of the testis and special cells of the theca interna of the ovary are the major sources of gonadal steroids. Lobule boundary cells are considered homologous with the Sertoli cells of the testis and the granulosa cel...
