МатериалMeroplankton of the Black Sea and seasonal dynamics of mussel larvae at experimental marifarm region(Trieste, 1990) Murina, V. V.; Artemjeva, Ya. N.; Kazankova, I. I.The distribution of meroplankton at the Black Sea is described. Seasonal dynamics of larval number and juvenile settlings in the region with experimental mussel farming are discussed. МатериалPopulation-genetic investigations of Black Sea Mytilus galloprovincialis Lam.(Trieste, 1990) Ivanov, V. N.; Bulatov, K. V.The population structure of Black Sea Mytilus galloprovincialis Lam. is analysed using karyotype date (n=28), phenetic polymorphism of mussels sampled from different biotopes. The selection was in favour of blackviolet specimens from collectors and rocky settlements, of striped and brown specimens from silty settlements. Cultivation of mussels with blackviolet shell colour is more profitable for marifarms. МатериалPrognosis for mussel farming inﬂuence on the environment basing on the mussel energy budget(Trieste, 1990) Kholodov, V. I.Functional characteristics of experimental mussel farming are evaluated based on qualitative data for mussel energetic balance. Rates of excretion and substance consumption by mussels during their cultivation are defined. Peculiarities of marifarm impacts on the environment are discussed. МатериалRegularities in mussel settlement formation on artificial substrates(Trieste, 1990) Ivanov, V. N.; Kholodov, V. I.; Bulatov, K. V.; Kazankova, I. I.; Pirkova, A. V.The paper deals with study results regarding structure formation of mussel settlements at mariculture farm collectors: larval settlings, dynamics in size, genetic and sexual structure of settlements, mollusc growth and its dependence on environmental conditions. МатериалDynamics of reproductive cycles, size and mass correlations of cultured mussels (Mytilus galloprovincialis Lam.)(Trieste, 1990) Pirkova, A. V.Dynamics of reproductive cycles of cultured mussels Mytilus galloprovincialis Lam. in the Southern Crimean region and seasonal evaluations of relative values of soft tissues as a consequence of reproductive activity are described. Some actions of biotic and abiotic factors influencing gametogenesis synchronization and mussel spawning are discussed. МатериалDynamics of phytoplankton community in the region with mussel marifarming(Trieste, 1990) Senicheva, M. I.In cold years big diatom and peridinium algae are the basis in phytoplankton biomass in the region with mussel mariculture farming. Mussels consump ultra and nanoplanktonic coccolithophorides, peridinia and small flagellates, mass development of which was watched during warm years. Actively filtrating and transforming into faeces and pseudofaeces a mass of planktonic algae mussels serve as meiorators in the environment. МатериалClimatic and physico-geographical conditions for mussel mariculture at the Black Sea(Trieste, 1990) Shalyapin, V. K.Climatic and physico-geographical peculiarities of some regions define feasibilities of mussel mariculture development at the Black Sea. Diurnal and seasonal changes of thermochaline water structure in the region with experimental mussel marifarming are given. МатериалRearing of viable juveniles of the Black Sea turbot in experimental conditions(Trieste, 1990) Bityukova, Yu. E.; Tkachenko, N. K.; Khanaichenko, A. N.; Vladimirtsev, V. B.Procedures and conditions on the Black Sea turbot Psetta maeotica (Pallas) rearing from artifically fertilized eggs upto the age of 240 days in experimental conditions are described. Transition to a bottom mode of life occurs at the age of 45-50 days, metamorphosis completes on days 70-80. Al the age of 8 months the mean length of Black Sea turbot was 13.85 cm, body weight was 59.5 g. МатериалEcological problems of mussel mariculture at the Black Sea(Trieste, 1990) Ivanov, V. N.The study of energy and substance fluxes is the productive-ecological basis for mussel mariculture arrangement at the Black Sea. Their optimization in ecosystems allows to rehabilitate the environment quality and to obtain commercial production.
