Get a job at the best local fish store (or fish farm if that is your goal) in the area. Work there for at least 2 years to learn the business inside and out and impress customers with your acquired knowledge and experience. You will learn everything you need to know to start your own business and maybe even start up with a customer base.
I think more of us don't do this because it's difficult to make enough profit to take a salary. Most are getting out of the brick-and-mortar fish store business and usually selling real estate sufficient for a fish farm is more profitable than using it to operate a business like this.
