I used to think that corvina were only a cool weather fish, but they *are* at La Pinta all year long. Have caught plenty of them in August. Try fishing the mud reefs that are just to the left as you come onto the beach, rather than the oyster reefs to the north. I've tried and tried, but never had very good luck catching anything further up the channel. And you've got it right - get there at low tide and you can scope out the mud reefs and cast out into the channel. The corvina come through in schools as the tide comes in. You can fill a bucket in a couple of minutes, then they move on. It's all about being at the right place at the right time. I will generally fish bait (squid) until I catch my first corvina, then I'll switch to a Kastmaster (the ones with the single hook and white bucktail are the best). 1/2 to 3/4 oz. I like throwing a Zara Spook, too, but only if there is no wind, which is rare.
