It sort of mimics real life lobster trapping. Legally (at least in some states in the US) you can only go catch lobsters in certain months. When is mini season, lobsters can only be of a certain size. Lobster boats usually go out during times they know lobsters are more abundant. It takes time and effort too in real life. If you do not want the hassle, you go to the market. Here in HD you hire tom or you hunt for it in shops :).
