Only a few years after the Palos Verdes Peninsula abalone stocks re-opened for commercial fishing in 1943, the stocks began to decline again, as more than 9.3 million pink abalone were collected during the peak decade of the fishery (Taniguchi 2013). The ups and downs of abalone stocks off of the coast of Southern California provide an example of how poor fishery management resulted in the collapse of a population. ![]() Though the media tends to focus on the effects of pollution, climate change, or overfishing, outdated systems of management are actually the main cause of the collapse in many cases. ![]() This news is perhaps not surprising as there are more examples of marine species collapses off our coastline than possible to list in this blog post.

The management and oversight of these fish stocks had not changed since 1959.
