^..1^ 68 deeply-indented coast--lines. A few shore rookeries have been observed in the northern part of the Sea of Okhotsk. In autumn, when fast ice begins to form, the seals concentrate in bays and inlets. The most numerous akiba conce,:trations at that time are obser.ved in the northern part of the ea, of Okhotsk, in 'Ushlci, Shelltinna, i'otykleislcii, Odyan, f
' 69. been discovered that Sea of Okhotsk ringed seals, beth male and female, become mature one year earlier than 'do the Loring Sea animals. - As with other seal species, development • of the embryo begins after a • delay of approximately two-and-ône-half months; the total duratio n . of gestation is about 11 months. ï'he moultinr; period begins in the last ten days in April; sexUally-immature animals are the first to change tneir fur covering. Se.?mally-mature males begin to moult in Hay, .and females somewhat later. r . 1-le peak of mass moulting occurs in the first ten days in June, and moulting is completed for most of the animals by the last dayS . of June; a small number of moulting seals can be obs ,...rved even • in.August. During the Moult the seals spend a large part of their time on the ice-floes, and make passive migrations as these drift. In . certain years, in areas where the ice lasts a•long time, fairly large concentrations of moulting akibas have been observed (in. the • coastal zone from Ushki Bay to Okhotsk, on the Shantarskie Islands, . and in Sakhalinskii Bay). • When the ice disappears and moulting is completed the akibas begin to feed vigorously, and they continue to do so. for seven or . eight months (summer, autumn, and winter months). During the summer and early autumn the.seals disperse through the open sea, and can be observed swimming singly or in groups; but when ice begins to appear they concentrate in the coastal zone, in bays and . • inlewts. .1'heir diet during that period has not been thoroughly investigated, as they are • only occasionally killed at that time. All available information on their diet refers mainly to their period of living on tne ice, when . they feed less intensively than.in summer and autumn. • The akibas' diet is varied, but the chief items in it are small planktonic crustaceans and, less . often, shrimps. I-oishes found in their stomachs include herring, navaga, Arctic . cod, s:,elts, sand . eels, capelin, and bullheads. In spring tne principal item, in the diet of Sea of Okhotsk ringed seals is planktonic crustaceans, concentrations of which tee seals find in patches of oen water and spacou between icC-floes. In autumn they feud mainly on fishes. in the B ovin g t;e , a considerable part of tin' diet consihts or Arctie owl, ;Ind prolnont anonr' crustnceans,arç: nnc 'mphioda. - it iG belleveu tiut the inhiba' s diet classifie it au a planLun-eaLer, • •
