Describe the effect of weather
Steenbergen 2015:
The weather is considered the most important factor for determining whether fishermen will go out fishing or not after the weekend. When shrimp catches are poor, and the expectation is that the costs will exceed the benefits, some fishermen will stay in the port but most will go out anyway. The rationale is that they at least want to give it a try, and if results are disappointing, they can return earlier.
