The first fisherman will catch 3*213 = <<3*213=639>>639 fish during the season.
The second fisherman catch 1*30 + 2*60 = <<1*30+2*60=150>>150 fish during the first 90 days of the season.
Then, during the remaining 213 - 90 = 123 days of the season, the second fisherman will can an additional 4*123 = <<4*123=492>>492 fish.
Thus, the second fisherman will catch a total of 150 + 492 = <<150+492=642>>642 fish.
Therefore, the second fisherman will catch 642 - 639 = <<642-639=3>>3 more fish than the first fisherman at the end of the season.
