Equations describing trawl complexes operation processes

Exploring deep-sea resources is an important step towards sustainable and efficient use of marine resources. Research may include analysis of biodiversity, ecosystem characteristics, and deep-sea fishing technologies and practices. Research in this area provides unique opportunities to advance understanding of the marine ecosystem for the development of deep-sea fisheries. This, in turn, helps to strengthen the sustainability and competitiveness of the Russian fishery complex in the long term. In the Russian Federation, the priority is to conduct scientific research in the field of deep-sea fishing, aimed both at developing the fishing of deep-sea objects and at studying them for the purpose of processing for the pharmaceutical industry. The development of innovative methods for catching mesopelagic fish and deep-sea aquatic organisms is an important task for the scientific community of the Russian Federation. The equations designed to describe various processes that occur during the operation of bottom and mid-depth trawl systems are discussed. The complexity of solving the above equations indicates the advisability of dividing exploitation processes into micro-level, macro-level and meta-level. The theory of multiphysics similarity allows you to simulate processes at various levels. Computer programs are presented that make it possible to recalculate the results of model experiments from a model of a trawl complex to a full-scale trawl complex.
