| On the phytogenous beaches of the Black sea the most abundant species of Amphipoda-Talitroidea are Orchestia bottae M.-Edw. The maximum biomass of these animals reaches from 1/8 to 1/10 part of the total weight of substratum. The calorific value of Orchestia was determined simultaneously with a bomb calorimeter and chemical method of combustion. The variability of calorific content within the size group of Orchestia from 1 to 120 mg was relatively constant during the year. Mean calorific value of dry matter have been equal 4.7 Kcal/g. Between the caloricity of unit of ash-free weight (y) and content of organic matter in the animals in percent (x) a straight line relation was found: y = 0.0945*x - 2.55. An increase of caloricity is connected with... |

| Cercaria owrean(Hutton, 1952) was found in the intestine of Sagitta inflata from plankton of the Gulf of Mexico. The pelagical fish of the Mediterranean basin was found to have cystless metacercaria of the family Accacoeliidae. They infect Trigla pini, Naucrates ductor, Myctophum punctatum, Diplodus annularis and Spicara smaris. As many sea invertebrates, the fish is included into the cycle development of Accacoeliidae and used as a supplementary or reservoir host. |

| The size-weight relations, caloric value, fat content, number of eggs produced, respiration and growth of Artemia salina were determined. According to the data obtained the total energy budget for Artemia has been calculated for different periods and for the whole life-time equal to 130 days. The energy of the food assimilated during the whole life is 60 calories per animal, and 120 cal of consumed food. A shrimp consumes during this time 24 mg of dry weight of food, the latter amounts to 5 cal/mg. The daily ration during the reproduction period was found to be 0.2 mg of dry weight of food per specimen, that gives about 40% of dry body weight of Artemia. The growth coefficient of the first order (K1) and the second order (K2) were determined. The first is... |

| The rate of the total nitrogen excretion by Nereis diversicolor Muller was studied. It was shown that this value correlates with body weight and is described by functional equation N = 0.82*W^0.63, where W - dry body weight, N - nitrogen excretion in mg/day. The relation between the rates of nitrogen excretion and oxygen consumption was expressed by equation N/Q = 0.078*W^-0.1. Our analysis of the data in literature shows that the correlation between nitrogen excretion and body weight exists also in all Vermes phylum. This suggests that the above mentioned correlation is manifested in animals regardless their belonging to different systematic position and age groups. |

| Protein composition of the blood serum of horse mackerels from the Black sea, the Red sea and the Mediterranean and 5 species of the Atlantic horse mackerels from the west coast of Africa was studied by the method of paper electrophoresis. It was found that protein pattern of the blood is that of specific in each species studied. This specificity is marked either in different quantity of their protein fractions, or in their quantitative interrelation or in different features of their statistical distribution. Individual variations and sex differences in quantitative interrelation of protein fractions are considerable only during the spawning period. As for the protein composition of the blood serum, differences among subspecies within a species are less... |
