title: Monitoring of mineral nitrogen concentration as a possible factor of influence on the results of valvometry of mussel kept in non-flow conditions with food deficiency
abstract: We investigated changes in the content of mineral forms of nitrogen formed as a result of mussel vital activity in non-flow conditions under favorable temperature and aeration, but with food deficiency, as a possible factor influencing mussel flap movement and valvometry results. A laboratory 11-day experiment was carried out with mussels 24–26 mm long. The dry weight of their soft tissues was about 35 mg. The experiment consisted of five exposures lasting 17-67 h. The mussels were kept in 3-lit
