About the Ludlum Thorofare
Ludlum Thorofare is one of the channels threading the salt marsh behind Sea Isle City, part of the extensive back-bay system that runs the length of the Cape May County barrier islands. A thorofare in the local usage is simply a natural channel connecting one stretch of bay to another, and this one carries a substantial volume of water on every tide between the marsh flats on either side.
Tide is the organising fact of fishing here, and the gauge reflects it directly, reporting water temperature alongside the tidal stage. The channels drain and fill hard, and fish position themselves to take advantage of that. A moving tide concentrates bait at the channel edges, on the points where creeks enter, and over the sod banks that flood and empty. Slack water is generally the least productive part of the cycle. The temperature series matters for run timing, as it does across the back bays, because the shallow marsh water warms and cools much faster than the ocean and the fish respond to that rather than to the calendar.
Summer flounder are the mainstay through the warm months, drifted over the channel bottom and along the edges. Striped bass work the marsh and the sod banks, best early and late and through the autumn. Weakfish appear in variable numbers and are a shadow of the historical fishery, which is worth stating rather than glossing. Blackfish and sea bass hold on any hard structure. Blue crabbing through the back bays is a genuine attraction in its own right during summer. This is shallow water, and navigating the marsh channels at low tide demands local knowledge or a very careful eye on the chart.

Seasons
Spring: bass move into the warming back bays ahead of the ocean, and early flounder appear in the channels.
Summer: flounder dominate the thorofares, with crabbing excellent and bass fished at first and last light.
Fall: the best season, with bass and bluefish feeding hard on bait leaving the marsh through the channels.
Winter: cold and largely finished, with the back bays empty and the inlets the only real option in mild spells.
