(MENAFN- The Peninsula) Rising sea temperatures have led to large-scale death of fish stocks in Qatar and elsewhere in the region, say researchers.
An expert has said that 18 types of fish, some of which are quite popular, have been affected as Qatari and Gulf waters have warmed more than expected this summer.
Among these fish species are Sahri, Jesh, Safi and Rabib.
However, this is not the first time increased sea temperatures have led to destruction of large-scale fish stocks in the Gulf waters. The phenomenon was first noticed by researchers in 1996 and it recurs either every year or every two years.
Researchers say that most deaths take place in the last week of August or first week of September.
Other factors responsible for the destruction of fish stocks is decreased ratio of dissolved oxygen in the water, strong sea currents and high wind.
A research vessel belonging to Environment Studies Centre of Qatar University, named Janan, was used in the latest study.
The research team comprised experts and researchers from the centre as well as those from the Ministry of Environment.
The Coast Guard of the Ministry of Interior collaborated in the research initiative, reports QNA.
The researchers found out that the temperature of the Gulf water has risen considerably. They didn't, however, cite figures.
The research vessel has devices to measure sea water salinity, purity, transparency, density, temperature and the ratio of oxygen.
Water samples have been taken from places and will be tested for quality. The devices took measurements seven, 14 and 29 metres deep in the sea water.
Mohamed Saeed Al Mohannadi, Director, Fisheries Department at the Ministry of Environment, and Dr Ibrahim Mohamed Al Ansari, from Qatar University, were part of the research team.
