Excerpt from Fish Culture
The discovery of how to artificially fecundate fish ova has been claimed for many different persons, in various ages, and in widely separated countries. In the fifteenth century a monk named Dom Pinchon appears to have practised it, breeding and rearing fishes in wooden boxes through which a stream of water flowed. The bottom of these boxes he lined with sand or gravel, while their ends were protected by wicker basket-work. Stephen Ludwig Jacobi, a wealthy landed proprietor, residing at H obenhausen, a small town in Westphalia, as early as 17 58 appears likewise to have made many experiments respecting the artificial breeding of salmon and trout, adopting much the same plan as Dom Pinchon, except that he secured both the upper surface and ends of his troughs with fine gratings and deposited them in the stream at a suitable depth leaving the eggs to be naturally hatched. He gave an account of his discovery in a letter to Bufi'on, which was deemed so important that the British Government granted him a pension.
