Opis:: The basic fish-breeding and biotechnological and biological indicators of yearlings of scaly carp grown in recirculation installations using forage mixture of natural food objects were researched. It was established that the introduction of natural fodder for feeding carp in controlled conditions positively affect the growth of fish. Using histological studies it was determined that in terms of growing fish in closed water plants, feeding fish with natural feed ingredients have positive effect on the metabolism in the body of the fish.

Opis:: The crossing number $ \text{cr} (G) $ of a graph $ G $ is the minimum number of edge crossings over all drawings of $ G $ in the plane. In the paper, we extend known results concerning crossing numbers of join products of four small graphs with paths and cycles. The crossing numbers of the join products $ G^∗ + P_n $ and $ G^∗ + C_n $ for the disconnected graph $ G^∗ $ consisting of the complete tripartite graph $ K_{1,1,2} $ and one isolated vertex are given, where $ P_n $ and $ C_n $ are the path and the cycle on $ n $ vertices, respectively. In the paper also the crossing numbers of $ H^∗ + P_n $ and $ H^∗ + C_n $ are determined, where $ H^∗ $ is isomorphic to the complete tripartite graph $ K_{1,1,3} $. Finally, by adding new edges to the graphs $ G^∗ $ and $ H^∗ $, we are able to obtain crossing numbers of join products of two other graphs $ G_1 $ and $ H_1 $ with paths and cycles.

Opis:: The main aim of this paper is to give the crossing number of the join product $G^∗ + P_n$ for the disconnected graph $G^$∗ of order five consisting of the complete graph $K_4$ and one isolated vertex, where $P_n$ is the path on n vertices. The proofs are done with the help of a lot of well-known exact values for the crossing numbers of the join products of subgraphs of the graph $G^∗$ with the paths. Finally, by adding new edges to the graph $G^∗$, we are able to obtain the crossing numbers of the join products of two other graphs with the path $P_n$.
