Project summaryObjective of the project – Development and demonstration of the pond pisciculture intensification technology by creating comfortable biological conditions by means of water aeration in ponds and by enrichment of the natural food ration for pond fish during the first and second years of life, applying a solar energy photovoltaic system (PV-system) as an energy source.
Task description: In the Republic of Belarus and some other regions in the world the pond farms are mainly located on peatbogs and marshes, which creates peculiar hydro-chemical conditions: namely the contents of the incoming water, bottom grounds, wind conditions, evolution of phito- and animal plankton, presence of macorphytes, etc. Preliminary research proves that an increase in efficiency of such ponds is possible at the expense of water aeration and widening the content of proteins in the food ration of fish (Generation Solar Renewable Energy Systems: agricultural_appl. htm//www.generationsolar.org). PV- systems are deemed as an optimal energy source for intensification of pond pisciculture for they do not demand expensive maintenance and disposable materials, are environment-friendly, feature long service life (20-30 years), and can be controlled automatically (Hubert Aulich and Wilchelm Schutze First published in Renewable Energy World November-December 2002.www.jxj.com/magsandj/rew/index.htm). High death rate among fry in Belarus pond pisciculture, caused by oxygen deficiency and lack of proteins in food ration, results in low profitability of the pond pisciculture, in this connection the application of the intensification technology is considered a very important and poignant task.
Impacts of the suggested project on the progress in the field of pond pisciculture rests in expanding the world science knowledge regarding improvement of biological conditions of fish breeding in ponds located to the north of latitude 500 North, predominantly in peatbogs and marshes, as well as widening the experience of application of solar energy systems in this region. The project creates necessary prerequisites for industrialization of the branch to diminish the influence of climatic and landscape factors on the product yield indicators.
Project participants are represented in the team by expert groups of 4 (four) companies. The BSUIR expert group, with some of the members being experts in the missile technologies field, is in charge for developing an automated system of the technological process control. The group of specialists representing the Fish Industry Institute, some of who are experts in the field of biological weapons, will carry out research of biological characteristics of breeding ponds, fry conditions at all phases of the technology development and demonstration. The group of specialists representing the Power Engineering Institute some of who are experts in the field of missile technologies, will develop and test the aeration and pond illumination system. The group of specialists representing Plastma Co., some of who are experts in the field of missile technologies and chemical weapons, will design the PV-system and carry out its full-scale testing. The competence of the participants on the project subject is well-proved by their publications.
Expected results: Upon solving 5 target tasks of the project the following results are expected to be gained.
- The oxygen conditions and piscicultural indicators will be determined under conditions of both regular and intensive pisciculture in the Republic of Belarus.
- The technological equipment will be developed, including: an automated control system, diffusion-type aeration system, pond night-illumination system, self-contained photovoltaic power supply system.
- The pond pisciculture intensification technology with aeration production processes applied will be developed.
- A package of the technological equipment will be produced.
- The pond pisciculture intensification demonstration and proving of the technological steps in full-scale environmental conditions will be executed.
Applied value of the project is estimated as a least of 20% increase in the fry yield and 30% increase in the average fry mass. Scientific value of the project is confined to an integrated solution to the problem of the pond pisciculture intensification by means of providing optimal oxygen conditions and refinement of the natural food ration of fish using solar energy. Commercial value of the project is determined by economy of the pond fish larvae and enhanced yield of fry, thus resulting in increase in the annual profits of the branch.
Intellectual property under the project is subject to protection.
Application of the project results is possible at pond farms, situated in the regions to the north of latitude 50 North, in peatbogs and marshes.

Role of foreign collaborators:
In the frame of the project it is planned to cooperate with the Collaborators in the below mentioned areas:
- Exchange of scientific information during the project;
- Commenting on the reports to be submitted by the project participants to the ISTC;
- Cross checks of the results, gained in the course of the project;
- Expert evaluation and estimation of the equipment and technology to be developed under the project;
- Rendering assistance in purchasing equipment to fulfill the project tasks and objectives;
- Arrangement of joint symposia and workshops.
Technical approach and methodology:
The evaluation of the pond oxygen conditions will be performed by thermooxyometric method, the phytoplankton condition will be estimated with the aid of the Fooks-Rosental chamber, the piscicultural indicators will be determined by means of catching and weighing the young fish in the base and check ponds.
The automated control system (ACS) design will rest on the microcontroller system operation principle on a basis of a programmable logic integrated circuit (PLIC) with an option of its computer-reprogramming supported.
The aeration production system design will rely on the results on the biological and ecological monitoring as soon as the system efficiency will have been experimentally proved at the breadboarding stage. The PV-system design will be grounded by the estimates of time and territorial potentials of the PV-conversion over the territory of the Republic of Belarus, of the solar modules efficiency, and of launch characteristics of loading devices.
The intensification technology will be implemented by regulating the technological operations of the equipment with subsequent monitoring of the biological characteristics of the ponds and piscicultural indicators. The technological equipment manufactured will be integrated in a single package, methodologically controlled by the ACS system according to a preset algorithm. The technology demonstration will be performed during both summer and winter periods, accompanied by a set of statistical data and the feasibility study of the project results industrialization.
