Humoral Factors Influencing Erythropoiesis in the Fish (Blue Gourami—Trichogaster trichopterus)

Humoral factors influencing erythropoiesis in the fish (blue gourami. Trichogaster trichopterus).

STRONG EVIDENCE has accumulated to indicate that erythropoiesis in mammals is under the control of a circulating principle, the erythropoiesisstimulating factor ( ESF ) or erythropoietin.1’2 A similar regulatory system may be operative in amphibians and birds.3’4 The ESF appears in large quantities in the plasma of animals subjected to bleeding or low oxygen pressures’ and its production is inh...

Factors influencing fish prices in Southern Malawi

Nine markets in the Southern Region of Malawi were studied. The prices of 79 separate purchases were compared for market type, species, form of preservation, total length, distance of retail market from the capture fishery of origin, and distance of retail market from the main commercial center of Blantyre. Interviews with retailers and consumers were conducted to help interpret price data and ...

Somatolactin Transcription during Oogenesis in Female Blue Gourami (Trichogaster trichopterus)

Somatolactin (SL), a specific pituitary hormone belonging to the prolactin (PRL) super family, is involved in background adaptation, osmoregulation, reproduction and fatty acid metabolism. The goal of this study was to examine the gene transcription of SL changes in the ovary of blue gourami females (Trichogaster trichopterus) during oogenesis by quantitative real-time polymerase chain reaction...
