Yes, but not until you have your Scuba Fishing Certification. As per Wiki:
Description: "Wranglers will receive their Scuba Fishing Certification once they complete this difficult and time consuming process. Unlike all other courses that are simply "theory" based, the Scuba Fishing Certification mandates every wrangler to have a minimum attempts at scuba fishing before receiving the certification. While preparing for the certification, you are allowed to scuba fish up to fifteen times a day. Once receiving your certificate, you will be able to scuba fish without restrictions."

Until you receive your license, you do not get any crew trips and cannot night fish at Sans Culpra. In addition, you run the risk of being caught by the Farovian Coast Guard if you fish more than 15 times.
In addition to the usual benefits of using Red Love Chum, each cast using RLC will count as four dives towards your license.
