BROWN TROUT OVA
FOR HATCHERY AT KANIERI. CONSIGNMENT OF 150,000 OVA. A consignment pf . 150,000 brown trout ova arrived on Tuesday from /■lnvercargill Ifor Lake Kanieri 'Hatchery. Owing to the fact that fre consignment did not arrive in Christchurch in time to connect with Saturday's express, the ova had to remain in Christchurch ove>- the rveek-eud and did not arrive in Hokitika until Tuesday morning.

By a peculiar coincidence, during the last weekend. t' N e water in the lak° had so lowered during the fine spell, that the old pipe line was not giving an adequate ‘supply and the Ka-nieri Electric Coy’s water race had again to be resorted to, but as .all danger from lime had then pasfed the hatchery water supply suffered no serious interruption-
