The aryicle presents the results of a comparative study of the biochemical composition of earthworms of dendrobene and prospector rocks, the peculiarities of their cultivation and their use for feeding when growing juvenile tilapia and clary catfish. The experience of cultivating earthworms of two breeds using the improved methods of foreign authors is described. The results of a study of the biochemical composition of cultivated objects that determine their nutritional value for feeding fish are presented. The fish-breeding and biological indicators of juvenile tilapia and clary catfish, obtained during the cultivation of dendrobene and prospector in fish farming in the Almaty region (VI fish-breeding zone) during worm feeding, are analyzed. A comprehensive analysis of the studied indicators made it possible to assign a certain rating place to each worm breed in relation to its use as fish feed.

This paper summarizes experiences from independent HIL testing of DP system software on more than 80 DP drilling, shuttle tanker, supply, anchor handling, construction and special purpose vessels. The paper includes examples of typical findings and a comprehensive analysis of finding statistics. The analysis shows how errors and weaknesses in core software and system configuration are distributed on the different functions in the DP system, as well as the potential consequence these errors could have had if they had not been identified and solved through early testing. The presented experiences demonstrate that independent testing of control systems using HIL testing technology is an important and effective service to ensure safe and reliable operation of offshore vessels.
