Study of environmental parameters of some water tanks and their aquaculture possibility from Sana’a governorate, Yemen

Abstract

Freshwater bodies in dams play an important role in providing local communities with several needs. Its aquatic ecosystems may help them in improving their socio-economic life, including aquaculture operations. Analyzing the water quality is an essential criterion for protecting aquatic ecosystems. The present study has investigated the water quality of chosen two tanks (i.e. Kamaran & Mesaibeeh water tanks, Sana'a Governorate, Yemen) in order to ensure their suitability to be used as a fish culture. Water sampling was conducted at monthly intervals between April 2013 and March 2014, and analyzed for the most important physio-chemical parameters in order to check their quality. The results of water's physio-chemical of the two studied sites in the present investigation have shown suitable water quality conditions for fish culture with regards to temperature, DO, pH, and TDS. Essential nutrients, for aquatic organism's growth (nitrate, nitrite, and phosphate), have been found at acceptable values in the two studied sites. The present study has shown a very good possibility for freshwater tanks to be used in aquaculture activities that may play an important role in providing a new source of aquatic food in the studied area and improving the socio-economic condition of the surrounding communities as well.
