Yellow-bellied sea snake (Pelamis platurus)

Weekly fish report

Inshore: The 1/2-day boats have started concentrating more on the up and down fishing for rockfish, whitefish, sheephead and an occasional lingcod or halibut. Sand bass and calico bass are picking back up a little. With the lack of bait and large sand bass in San Diego bay the past couple winters, those fishing the bay bass tournament in 2016 are pre-fishing for the larger calico bass off the pilings and structures towards the bay mouth. There’s pelagic fun for all this year, as yellowfin and skipjack tuna have been caught by inshore kayakers and even a few reported caught from Imperial Beach Pier.

Outside: Wahoo! There have been quite a few wahoo caught in San Diego waters from both sportfishers and private boaters, even as far north as off Ventura. Wahoo were photographed through the glass-bottom tour boat at Catalina Island. This year has been the best opportunity to catch one of the toothy speedsters within 20 miles of Point Loma in a lifetime. The yellowfin tuna numbers continue to drop though they are out there pretty thick. Dorado counts are still dropping a bit, but occasionally a boat comes across a kelp paddy loaded with them. There are still some striped and blue marlin ranging about along with some shortbill spearfish.

10/11 – 10/17 Dock Totals: 3,947 anglers aboard 161 boats out of San Diego landings caught 70 wahoo, 7,557 yellowfin tuna, 22 bluefin tuna, 1,593 yellowtail, 657 dorado, 1,792 skipjack tuna, 469 calico bass, 428 sand bass, 13 barracuda, 1,433 rockfish, 80 sheephead, 8 rubberlip seaperch, 5 halibut, 731 bonito, 29 whitefish, 1 lingcod, 1 shortbill spearfish, 1 white seabass and 88 spiny lobster. Notably, a ¾ day trip mid-week to the Coronado Islands carrying 10 anglers boated 29 wahoo.

On the Beach: A few yellow-bellied sea snakes washed up at high tide along the Southern California coast to as far north as Oxnard. The highly-venomous reptile, thought to be a descendant of Australian tiger snakes, aren’t very aggressive but they do carry one of the most deadly toxins and should not be handled if found. Report their location to the local authorities as soon as possible, preferably with GPS numbers. There is no reason to panic, but do be aware that the ocean life normally found in tropical regions is now coming ashore closer to home. The last time they appeared in California was during the El Niño in the '80s.
