Human Interactions
The Izak catshark is harmless and of no commercial value. It is regularly caught incidentally (and discarded) by a bottom trawl fishery targeting hake south of Cape Town. In contrast to most cartilaginous fishes, its numbers have been increasing in the presence of commercial fishing. The reasons for this may include its high reproductive rate, its breeding in less-fished shallower waters, its hardiness allowing for high post-capture survival, and its opportunistic diet. The International Union for Conservation of Nature (IUCN) has consequently listed the Izak catshark under Least Concern, while still noting that it merits continued population monitoring because of its highly restricted range.

Famous quotes containing the words human and/or interactions:
“The human imagination ... has great difficulty in living strictly within the confines of a materialist practice or philosophy. It dreams, like a dog in its basket, of hares in the open.”
—John Berger (b. 1926)
“In child rearing it would unquestionably be easier if a child were to do something because we say so. The authoritarian method does expedite things, but it does not produce independent functioning. If a child has not mastered the underlying principles of human interactions and merely conforms out of coercion or conditioning, he has no tools to use, no resources to apply in the next situation that confronts him.”
—Elaine Heffner (20th century)
