Rare species of fish re­leased to wa­ter basins

Azer News - - Miscellaneous - By Narmina Mam­madova

AAs many as 370 mil­lion young fish of var­i­ous species were re­leased into the wa­ter basins of Azer­bai­jan in Jan­uary-Septem­ber 2018.

This was stated by head of the de­part­ment for in­creas­ing and pro­tect­ing the bi­o­log­i­cal re­sources of wa­ter basins of the Min­istry of Ecol­ogy and Nat­u­ral Re­sources Farida Alek­berova, Az­ertag re­ported.

Alek­berova said that, 75,000 fry be­long to salmon breeds, 7.59 mil­lion - to stur­geon, and 362 mil­lion of them are carps.

Nine species of fish were on the verge of ex­tinc­tion in Azer­bai­jan in 2014. These in­cluded bar­bel cha­nari, Caspian trout (salmon), sea pike perch, Chekhon, Caspian bar­bel, South Caspian white-eyed and spike, river trout and shir­van roach.

These species of fish are rare at present, and one of the rea­sons for this is the lack of spawn­ing grounds, Se­nior Re­searcher of the Ichthy­ol­ogy Lab­o­ra­tory of the Zo­ol­ogy In­sti­tute of the Na­tional Academy of Sciences of Azer­bai­jan Namig Mustafayev be­lieves.

The sci­en­tist noted that the ma­jor­ity of Caspian fish rise along the rivers to spawn, but can­not en­ter 90 per­cent of the rivers and swim the re­quired dis­tance be­cause of the con­struc­tion of reser­voirs.

A de­crease in the stur­geon pop­u­la­tion was in­flu­enced by a de­crease in food sup­ply and il­le­gal fish­ing. The pol­lu­tion of the Caspian oil also played a role in re­duc­ing fish pop­u­la­tions, the sci­en­tist stated.

Ac­cord­ing to sci­en­tists, usu­ally poach­ing is one of the main rea­sons of re­duc­ing fish pop­u­la­tions.

Last month, in con­nec­tion with the start of the fish­ing sea­son, the Wa­ter Trans­port Po­lice De­part­ment of the Gen­eral Direc­torate of the Po­lice for Trans­port un­der the In­ter­nal Af­fairs Min­istry launched raids to iden­tify peo­ple en­gaged in il­le­gal fish­ing.
