A Memory of the Southern Seas by Louis Becke

The sea salmon make their appearance on the southern half of the eastern seaboard of Australia with undeviating regularity in the last week of October, and, entering the rivers and inlets, remain on the coast till the first week of December. As far as my knowledge goes, they come from the south and travel northwards, and do not appear to relish the tropical waters of the North Queensland coast, though I have heard that some years ago a vast "school" entered the waters of Port Denison.

Given a dear, sunny day and a smooth sea the advent of these fish to the bar harbours and rivers of New South Wales presents a truly extraordinary sight. From any moderately high bluff or headland one can discern their approach nearly two miles away. You see a dark patch upon the water, and were it not for the attendant flocks of gulls and other aquatic birds, one would imagine it to be but the passing reflection of a cloud. But presently you see another and another; and, still farther oat, a long black line flecked with white can be discerned with a good glass. Then you look above -- the sky is cloudless blue, and you know that the dark moving patches are the advance battalions of countless thousands of sea salmon, and that the mile-long black and white streak behind them is the main body of the first mighty army; for others are to follow day by day for another fortnight.
