Luanda — Angolan deputy minister of Fisheries, Vitória de Barros Neto, said Wednesday in Luanda that many world marine species are threatened with extinction, due to climatic alterations and men's perverse action on their habitats.
The deputy minister was speaking at the opening of the 14th Techno-scientific Events of the National Institute of Fishery and Technological Research that is going on under the motto "The climatic changes and new challenges to fishery and technological research".
According to the official, temperature, lead and oxygen constitute a restraining factor to many marine species.
Alterations to any of these factors, she added, puts at risk the survival of many species, with stress to the fishery resources that are naturally subject to fishing pressure.
The deputy minister stated that the coral reefs (locals of material concentration where big school of fish are found), important for the ocean species, are in decline, due to global warming.
She added that many experts predict the complete decline of the living resources of the sea until 2024, should the actual situation remain unchanged.
Meanwhile, INIP director, Francisca Delgado, said the easiest way of following the ecosystem changes consists in a regular measurement of some parameters of the sea and atmosphere, like temperature, concentration of oxygen, lead, height of the sea tide at the coast or on pre-determined points.
This afternoon, the specialists are discussing such topics as seasonal and inter-annual variabilities of sea and chlorophila superficial temperature at the Angolan coast, the role of meteorological information in the study of marine environment and some signs of climatic changes at the Angolan coast.
Attending the meeting closing Friday are officials from the Fisheries Ministry, INIP, local guests and others from Portugal, South Africa and Norway.
