The natives are very skilful in this mode of fishing, and it is an interesting sight to see several of them in the water diving together, and exerting themselves against each other in their efforts to catch the best fish, whilst the affrighted inhabitants of the water swim wildly and confusedly about, seeking shelter in the mud and weeds, only to become an easier prey. I have even seen natives dive down in the river, without net or implement of any kind, and bring up good-sized fish, which they had caught with their hands at the bottom.
Another method of diving with the net is conducted on a larger scale. The net itself is made of strong twine, from six to eight feet long, oval at the top, about two feet across, and two deep. It is looped to a wooden hoop or bow, with a strong string drawn tightly across the two ends of the bow, and passed through the loops of the straight side of the net. With this two natives dive together under the cliffs which confine the waters of the Murray, each holding one end of the bow. They then place it before any hole or cavity there may be in the rocks beneath the surface, with the size, shape, and position of which they have by previous experience become well acquainted; the terrified fish is then driven into the net and secured. Fishes varying from twenty to seventy pounds are caught in this way. It is only, however, at particular seasons of the year, when the female fish are seeking for a place to deposit their spawn that this mode of fishing can be adopted.
Other kinds of hoop-nets are used for catching fish in shallow waters, or for taking the shrimp, and a small fish like the white-bait, but they need not be particularly described.
The next principal mode of procuring fish is by spearing them, and even this is performed in a variety of ways, according to the season of the year, the description of fish to be taken, and the peculiarities of the place where they are found. In the shallow waters upon the sea-coast the native wades with his spear and throwing-stick, and follows the windings of the fish with singular rapidity and skill, rarely missing his aim where he has an opportunity of striking.
In the larger rivers, when the waters are low and clear, a party of natives varying in numbers from five to forty plunge in with their spears, which for the purpose are made of hard wood, with smooth, sharp points, and about six feet long. Forming themselves into a large semicircle in the water, they all dive down, simultaneously, with their weapons, accompanied sometimes by a young man, a few yards in advance of the middle of the party, and without a spear. For a considerable time they remain under water, and then, if successful, gradually emerge, and deliver the fish that have been speared, to their friends on the shore. If unsuccessful they swim a few yards further down, and dive again with their weapons. And thus they frequently go on for a mile or two, until they are either tired or satisfied with their success. I have known a party of thirty natives kill seven or eight fish in the course of an hour, none of which were under fifteen pounds, whilst some of them were much larger.
