Basket fish traps.
Basket traps, of different forms of construction, are much used by Indians for the taking of fish. Some are simple in the extreme, and much resemble a lady’s crinoline. With it the native wades about in the wide shallow lakes, keeping the bell-shaped mouth downwards, and frequently striking the bottom with it. When a fish happens to become inclosed, it immediately darts off and endeavours to escape; but its head coming in contact with the side of the basket, the shock is at once felt by the wader, who thrusts his bare arm down through the small or upper opening of his contrivance, and so secures his victim, who, when a strip of vine or ground cane has been passed through his gills, is allowed to trail after his captor. On the Zambesi the women wade in the clear shallow water with a funnel-shaped basket, the smaller end of which is prolonged by a pole or handle. When a fish is seen, the wide lower end of the basket is at once darted down upon him, and he is captured at leisure.
Wicker cages of trumpet form, constructed much on the principle of the ordinary eel basket, appear common amongst the aborigines of nearly every part of the world. Some we once discovered when hunting in the Bheel country were of most elegant form, and woven entirely from the finely-split fibres of single bamboo joints, the knot being left entire at one end, to form a ring through which the bait is introduced. By some tribes of North American Indians long rods are used to form these, just as we employ willows. Some traps made in this way are very large. Huge baskets are often suspended and secured beneath waterfalls in the run of the salmon, which on missing their leap fall back into these traps. When a sufficient number have been inclosed, the Indians, armed with short clubs, enter the baskets and despatch the ill-fated fish, which are then cast out on the rocks to the dusky ladies of the tribe, who are waiting to receive them. On the Zambesi, the Bō-tlét-lē River near Lake Ngami, and in North Australia, the natives are very ingenious in the construction of dams or weirs; and creels or trap baskets are skilfully placed at the outlets. Some of these are of stiff reeds or osiers; others, of rushes so flexible as to be merely a bag or net. Long semicircular pounds are, by the natives of some countries, constructed of sticks and twigs between high and low water marks. The fish, getting embayed within these, are left high and dry as the tide falls, and are gathered up before the return of the waves.
Dams, weirs, and spears.
Dams and fishing weirs are built across streams by the inhabitants of most countries. At these the fish are either entrapped in hutches furnished with bars, on the eel-basket or sparrow-cage principle, shot with arrows, scooped up in hoop nets, or speared with hand spears of various forms. Some of these are perfectly simple in construction, whilst others are remarkably ingenious and curious. The annexed illustration (Fig. 1) represents one much used by the inhabitants of northern regions for the capture of the salmon. By the Esquimaux these implements are made principally of horn. The handles are of drift wood, neatly bound together with strips of tendon. The centre spikes are of sharpened bone, whilst the barbs in the jaws of the spear are usually made from two common iron nails, obtained by burning chance fragments of wreck. Fig. 2 represents the trout spear of the trappers. The tines are of steel, set in an iron head-piece.
Many of the natives of Africa and Australia are very skilful in the construction of dams and weirs. We have seen in some rivers the smaller channels effectually blocked against the passage of fish, which have at first been gently led—by very slight obstructions, and then forced by impassable barriers, narrowing like a funnel as they went on—to take the desired course, at the end of which creels or basket traps, sometimes of soft rushes, or in other cases of twigs or cane, have been set to receive them; while in sluggish waters, such as the Bō-tlét-lē River at Lake Ngami, long zigzag fences of reeds are set up, inclosing a considerable space, and narrowing gradually to several funnel-shaped outlets, at each of which one or more creels are set, belonging to various families. Openings are left in the lines for the ordinary passage of canoes; but when a “take” is to be made these are carefully closed, and the canoes in deep water, with a promiscuous medley of waders in the shallows, form an extended line, gradually closing in and driving the fish toward the traps.
