Department of Fish and Wildlife marine biologist answers angler questions.
SOUTHERN CALIFORNIA — The California Department of Fish and Wildlife (DFW) occasionally features an outdoor column to address questions about angling, fisheries and marine life, among other topics.
Marine biologist and DFW columnist Carrie Wilson answered questions about determining the gender of black bass, landing net regulations for kayak fishing and whether crossbow fishing is legal.
Below are the questions and answers as posted on the DFW website.
Determining the sex of black bass
Q: We fish Lake Silverwood most of the time, and usually it’s for bass. Is there a way to determine the sex of a largemouth bass? We are interested primarily in the fish we catch in the spring. Also, are crayfish part of the diet for bass in Lake Silverwood? (Doug T., Hesperia)
A: Unfortunately, there is no easy way to sex black bass (including largemouth bass) unless they are in spawning mode. The males move up first into the spawning areas and make the nests. The females then join them when they’re ready. When you see a pair on a nest, the male is usually the smaller of the pair and will be the most aggressive. A single female will mate with more than one male during the spawning season. And regarding their diet, yes, crayfish are part of the black bass diet.
Landing net size for ocean kayak fishing?
Q: What size opening on a landing net is needed for ocean fishing? I fish from a kayak between San Francisco Bay and the Mexico border, and all points in between. (Jeff K.)
A: A landing net is required when fishing from any vessel on the ocean. “No person shall take finfish from any boat or other floating device in ocean waters without having a landing net in possession or available for immediate use to assist in landing undersize fish of species having minimum size limits; the opening of any such landing net shall be not less than eighteen inches in diameter,” (California Code of Regulations Title 14, 28.65(d)).
Fishermen are ultimately responsible for being able to determine whether the fish they take are of legal size. When in doubt, your best bet is to consult the California Ocean Sport Fishing Regulations booklet.
Is ocean fishing with a crossbow legal?
Q: Is it legal to take fish in Southern California oceans using a crossbow? I know that using a bow and arrow is legal but I would like to know if crossbows are also legal. I also realize that the usual bag limits, size limits and closures apply. (Rod)
A: Spears, harpoons and bow and arrow fishing tackle (including crossbows) may be used for taking all varieties of skates, rays and sharks, except white sharks. Such gear may not be possessed or used within 100 yards of the mouth of any stream in any ocean waters north of Ventura County, nor aboard any vessel on any day or trip when broadbill swordfish or marlin have been taken. Bow and arrow fishing tackle may also be used to take finfish other than giant (black) sea bass, garibaldi, gulf grouper, broomtail grouper, trout, salmon, broadbill swordfish and white shark (CCR Title 14, section 28.95).
For hunting purposes, crossbows are not considered to be archery equipment (see CCR Title 14, section 354). But under the fishing regulations, crossbows qualify as bow and arrow fishing tackle. It does not matter what type of bow or crossbow is used under legal bow and arrow fishing, but a line must be attached to the bow and the arrow/bolt (CCR Title 14, section 1.23). If using a crossbow for shark fishing, be sure of the species and any associated size and/or bag limits before pulling that trigger.
