Mantis Shrimp

June 28, 2012

Question: What are the rules and regulations on the mantis shrimp? I accidentally snagged one with a hook and line and let it go because I knew nothing about it. I didn’t even know what it was until I got home and was able to research it. (Michael H.)

Answer: There are no specific regulations for these crustaceans, but they are protected by the general sport fishing regulations for all invertebrates and crustaceans (CCR Title 14, sections 29.05 and 29.80, respectively).  Invertebrates may not be taken by hook and line. Mantis shrimp can be taken in all ocean waters open to sport fishing, and everyone 16 years of age and older is required to have a fishing license. These feisty shrimp can be taken by hand, in a shrimp and prawn trap, or less likely but still legally, in a dip net or Hawaiian style throw net north of Point Conception (California Code of Regulations Title 14, sections 29.80(f), 29.80(i)). The bag limit is 35.

While these crustaceans may be legal to take by hand, please be extremely careful before trying to do so! According to DFG Environmental Scientist Jerry Kashiwada, this is an animal that should not be handled. Mantis shrimp have a front pair of appendages which look like a club, they open up like a switch blade knife and are sharp enough to cut through a neoprene dive glove. The movement is so fast, the person will not be able to react to avoid being cut.
