The mpasa, or sanjika, found by Dr.Kirk to be a kind of carp, was running up the rivers to spawn, like our salmon at home: the largest we saw was over two feet in length; it is a splendid fish, and the best we have ever eaten in Africa.

They were ascending the rivers in August and September, and furnished active and profitable employment to many fishermen, who did not mind their being out of season.

Weirs were constructed full of sluices, in each of which was set a large basket-trap, through whose single tortuous opening the fish once in has but small chance of escape.

A short distance below the weir, nets are stretched across from bank to bank, so that it seemed a marvel how the most sagacious sanjika could get up at all without being taken.

Possibly a passage up the river is found at night; but this is not the country of Sundays or "close times" for either men or fish.
