Review on Physic-Chemical & Ecological Elements on the Productivity of Fisheries

Understanding the influence of physic-chemical and ecological factors on fisheries productivity

Abstract

Water tests were gathered in five inspecting focuses as pursues four examples inside the tidal pond and the fifth one in the channel that associate the tidal pond with the ocean. The physical-chemical parameters of water were resolved following the examples were taken to the research center. Conductivity, saltiness and TDS were resolved with a direct meter (Model DDSJ 308A). pH and temperature, were estimated with a pH meter (Model pHS-3BW ). TSS (all out suspended mater) was controlled by pouring one liter volume of water through a pre-gauged channel of 0.42 µm pore size, at that point gauging the channel again in the wake of drying it at 105o C for 2 hours to expel all water. The centralization of broke down oxygen (DO) was resolved utilizing Winkler strategy. Supplements (nitrites, nitrates, ammonium and phosphates) substances were dictated by spectrophotometric techniques.
