Only one category saw a change in the leaderboard on the fourth day of the Middle-Atlantic $500,000 Marlin and Tuna Tournament on Thursday. Dave Anderson of Medford caught a 42-pound wahoo to take the lead in that category.

Many boats used Thursday as their second non-fishing day as only 52 boats went out. Boats can only fish three days of the five-day tournament.

Leaderboards remain the same for white marlin, blue marlin, tuna and dolphin. Today is the final day for the tournament. Weigh runs from 5 to 9 p.m. at the Canyon Club Resort Marina in Lower Township.
