TEHRAN, Jan. 16 (ISNA)-The World Conservation Union (IUCN) experts say Persian Gulf dolphins beaching was a result of fishing and its related factors.
Studies on the cause of death of 79 dolphins according to the data including the dispersion of the corpses along a 13-kilometer strip of the shore, fractures in skulls and almost simultaneous death time, proves that the death cause was fishing, IUCN expert Antonio Fernandez said to ISNA.
He, in regard to the death of the second school of dolphins which beached almost a month after the first school said sonar has no effect on dolphins because they live in the surface.
Although he had no clear explanation on the death of the 73 dolphins of the second school he counted environmental stress, oceanic factors and topographic situation of the beach as being effective in their death. He added that there were other reasons for the second school beaching and that IUCN has asked for other international experts' opinion.
