The Laboratory of salmonid culture and restoration of endangered fish species has been created for the restoration in Ukraine and significant increase in the species structure of fish culture objects due by using native salmonids and sturgeons. The primary attention is given to the conservation of the genetic pool of endangered fish species including Danube salmon, European grayling, brown trout, sterlet of Danube and Dniester populations.

The importance of the laboratory is related to the fact that slamonids belong to a rare complex of freshwater fish fauna of Ukraine, the conservation of which is task of national importance. Therefore, the artificial propagation and introduction into aquaculture of salmonids and endangered fish species currently became an important issue.

Research methods of the laboratory include generally accepted ichthyological, hydrobiological, and fish culture techniques. Moreover, for the approbation of technological schemes, we use in-house methods, which allow assessing the efficiency of the rearing of salmonids based on established criteria. Employees of the laboratory carry out joint studies with Presov University (Slovakia), with the Recreational Fishing Association (Poland) and French Aquaculture Association.

The aim of the department is organizing and conducting selective-breeding works with pond fish at fish farms of different forms of ownership.

Currently, the department of fish selection develops selective-genetic bases for the improvement of the genetic resources of aquaculture objects with the use of molecular-genetic methods and modern cryobiotechnologies. Lately, a significant progress was achieved in the freezing of fish sperm and its use for artificial reproduction of valuable, rare and endangered species as well as pedigree fish specimen valuable in selective aspect. In the nearest perspective, we planned to conduct the works on forming the new brood stocks of Ukrainian carp breeds and improvement of breed base of domestic aquaculture, to obtain and grow new genotypes of valuable aquaculture objects with the use of modern biotechnologies, to widen and implement novel achievements of molecular genetics into everyday practice of fisheries research and fish selection, including the use of markers base on mitochondrial DNA.

Major areas of the department activities:

  1. development of selective-breeding bases for improving the genetic resources of aquaculture objects;
  2. rearing and forming the improved stocks of aquaculture objects;

Propositions of services for individuals and legal entities:

  • consultative and practical aid on organizing and conducting selective-breeding works in aquaculture;
  • selective-breeding works at specific fish farms.

The Department of Fish Selection of the Institute of Fisheries created first in the former Soviet Union two carp breeds – Ukrainian framed and Ukrainian scaled carp, based on which a number of intrabreed types and arrays (ecological types) were created, including: Nivka intrabreed type (scaled form); little scaled type (framed form); Lyubin types (scaled and framed forms) as well as Antonisko-Zozulenetsk arrays (scaled and framed forms) and Nesvitsk arrays (scaled and framed forms).

The laboratory of biotechnologies in aquaculture was created in 2002 by the laureate of the State Prize of Ukraine in Science and Technics, Academician of the Russian Academy of Natural Sciences (RANS), Doctor of Biological Sciences, Professor Buchatsky Leonid Petrovych. The aim of the laboratory is application of genomic and proteomic techniques for increasing fish productivity including the use of recombinant DNA and stem cell technologies, production of unisexual fish populations, introduction of molecular-biochemical, molecular and cryobiological studies in aquaculture, development of effective methods for diagnostics and prevention of infectious fish diseases.

The importance of the laboratory work is related to the fast development of aquaculture and introduction of novel biotechnologies for meeting the world demands in aquaculture products. The biotechnologies in aquaculture are aimed at solving such important problems as: improvement of fish population genetic control, conservation of biological diversity, restoration of rare and endangered fish species, biosafety, control of infectious fish diseases, immunology and genetic engineering.

The laboratory uses following methods: production of embryonic stem cells and their cultivation, cryopreservation of genital products, wide spectrum of molecular-biological and biochemical methods. Modern biotechnologies allow increasing fish growth rate, increasing their resistance to infectious diseases, affecting their reproductive processes, producing improved hybrids. The application of biotechnologies in aquaculture also contributes to the study of fundamental problems in ichthyology, developmental biology, immunology, microbiology, virology, etc.

Major areas of the laboratory activities:

  1. development of diagnostic test-systems for the identification of infectious fish diseases;
  2. study of the immunomodulating properties of novel biologically active substances and preparation and their introduction into aquaculture;
  3. fundamental studies in gender genetics, polyploidy and distant hybridization;
  4. obtaining distant hybrids with the aid of disperm androgenesis and alkylated DNA;
  5. use of passaged cultures of fish cells in the study of “pathogen-host” immunological interactions;
  6. isolation of spermatogonial stem cells and recipient transplantation for improving the genetic properties of aquaculture objects, xenotransplantation;
  7. improvement of cryopreservation methods for fish genital cells.

Propositions of services for individuals and legal entities:

  • molecular express-diagnostics of infectious fish diseases (see the Table);
  • recommendations on the application of immunomodulating drugs;
  • procedure of distant hybridization;
  • search for genital DNA-markers for the express-diagnostics of sex in valuable fish species;
  • use of indirect feminization method and obtaining the special unisexual fish brood stocks for the need of fish egg production;
  • cryopreservation and storage of brood fish genital products.

During the laboratory existence, we developed the diagnostic systems based on polymerase chain reaction (PCR) for the identification of viral and bacterial fish diseases, which according to the International Office of Epizootics (OIE) are especially dangerous for the objects of modern aquaculture.

We developed a PCR method for sex diagnostics in rainbow trout, Danube salmon and European grayling. The identification of genotypic males is a key stage in the process of hormonal sex reversion and production of reversant males for further fertilization of native females for obtaining a 100% unisexual population.

The laboratory developed and currently works on the dehydration-vitrification method of fish sperm freezing, due to which we increased the efficiency of cryobiological studies more than by two-fold with the aid of significant decrease in time and material necessary for getting the necessary result.
