At 1,971 feet the Ocean Beach Pier is supposed to be the longest concrete pier in the world. It also has a T-shape at the end extending 360 feet to the south end and 193 feet to the north end. The far end extends into the Point Loma kelp bed and is blanketed by kelp much of the year. This can attract some kelp resident species but can also cause a lot of tangles, usually at the most inopportune time -- such as when you have a large fish attached to the end of your line. At this far end, where the water is 25 feet deep, the most common species are kelp bass, sand bass, several variety of perch, bonito, mackerel, scorpionfish, halibut and, quite often, California lobster.
