What Redfish Bay offers and how to fish it

Redfish Bay sits directly south of Aransas Pass and is one of the most productive shallow bays on the Texas coast for redfish and spotted seatrout. The bay runs roughly 12 miles north to south and averages 4 to 6 feet deep, with extensive flats, grass beds, and shell-lined channels that hold fish year-round. Most of the bay is wadeable or fishable from a shallow-draft boat, and the water clarity ranges from stained to clear depending on recent rainfall and tidal flow.

The redfish here run larger than in many other Texas bays—fish in the 24- to 28-inch range are common, and slot-limit fish (18 to 28 inches) are the target for catch-and-release anglers. Spotted seatrout share the same habitat and respond to identical presentations. The bay's shallow structure and abundant forage make it a year-round destination, though fall and spring are peak seasons when water temperatures and baitfish activity align.

Key Takeaways

  • Redfish Bay's shallow flats and grass beds hold redfish and trout in depths of 2 to 6 feet, making it ideal for wading or poling a shallow-draft boat.
  • Redfish here average 22 to 26 inches, with slot-limit fish (18 to 28 inches) protected by Texas Parks and Wildlife regulations.
  • Fall (September through November) and spring (March through May) are the most consistent seasons, though the bay produces year-round.
  • Access points include the Aransas Pass jetties to the north and public boat ramps at Fulton and Rockport, each about 20 to 30 minutes away by water.
  • Mullet, shrimp, and small baitfish are the primary forage; artificial lures that mimic these patterns work as well as live bait.

Seasonal patterns and water conditions

Fall is the strongest season in Redfish Bay. As water temperatures drop from August through November, redfish move from the deeper channels into the shallows to feed on mullet and shrimp. Tidal flats that were too warm in summer become prime habitat, and you can sight-cast to cruising fish in 2 to 4 feet of water. Trout also concentrate in the grass beds during this window, and both species are aggressive.

Winter (December through February) slows the bite but does not shut it down. Fish move to deeper channels and holes—the 6- to 8-foot cuts that run through the bay—and respond best to live shrimp fished on the bottom or slow-moving soft plastics. Midday periods when water temperature peaks are more productive than early morning.

Spring (March through May) mirrors fall in terms of activity. Warming water pushes fish back into the shallows, spawning aggregations form in certain areas, and both sight-casting and blind-casting produce. Summer (June through August) is the slowest season; fish retreat to deeper water and the bay's edges, and the heat makes wading uncomfortable during midday hours.

Tackle, lures, and live bait options

A 7- to 8-foot medium-power spinning rod with 15- to 20-pound braided line is the standard setup for Redfish Bay. Braided line cuts through the shallow water and grass without sinking, and the visibility does not matter much in stained bay water. A 12- to 18-inch fluorocarbon leader (20 to 25 pounds) prevents line-shy fish from detecting the braid.

Artificial lures work as well as live bait here. Soft plastics in the 3- to 4-inch range—paddletail shads in natural colors like pearl, chartreuse, and dark green—are the workhorse. Topwater plugs during low-light periods (dawn, dusk, and overcast days) draw explosive strikes from redfish in shallow water. Spoons and small jigs also produce, especially in deeper channels.

Live mullet (4 to 6 inches) and live shrimp are the traditional choice and often outfish artificials when fish are pressured. Cast live bait near grass edges, shell beds, and channel breaks and let it work naturally. A simple 1/0 to 2/0 circle hook on a 12-inch fluorocarbon leader is all you need; the circle hook often hooks itself as the fish swims away.

Wading versus boat fishing

Wading is productive and popular in Redfish Bay because much of the bay is 3 to 5 feet deep and the bottom is firm sand and shell. Wade the flats on incoming or high tide, when water depth allows you to move freely without spooking fish. Wear polarized sunglasses and move slowly; redfish in shallow water are easily startled by vibration and shadow. Early morning and late afternoon offer the best light for spotting cruising fish.

Boat fishing covers more water and works well when wading conditions are poor (low tide, murky water, or strong wind). Pole or drift the deeper channels and grass edges, casting ahead of the boat's path. A shallow-draft skiff (18 to 22 feet) is ideal because it lets you access water that deeper boats cannot reach. Many anglers use a trolling motor to hold position or move quietly across flats.

Access points and launch locations

The closest public boat ramp to Redfish Bay is at Fulton, about 20 minutes north by water. The Fulton ramp is maintained by Aransas County and has parking, restrooms, and fuel nearby. From Fulton, you run south through Aransas Bay and into Redfish Bay through the natural channel.

Rockport, about 30 minutes north, offers additional ramps and more amenities. The Rockport Harbor ramp is larger and handles more traffic, making it a good option on weekends when Fulton fills up. Both ramps charge a small launch fee (typically $5 to $10 per day).

Wading access is less formal. You can wade from the shoreline along the bay's western edge near Fulton, or from public beach areas near Aransas Pass. Check local regulations and tide tables before wading; some areas are private property, and low tide can strand you far from deep water.

Regulations and slot limits

Texas Parks and Wildlife sets the rules for Redfish Bay. Redfish are protected under a slot limit of 18 to 28 inches; you may keep one fish per day within this range, and all fish outside the slot must be released. Spotted seatrout have a 12-inch minimum and a two-fish daily bag limit. Both regulations change periodically, so check the current rules before you fish.

A valid Texas fishing license is required for anyone 17 and older. Licenses are sold online, at tackle shops, and at most sporting goods stores. A saltwater stamp is included with most license types and covers bay fishing.

Tides and timing

Redfish Bay is a tidal system, and tide movement directly affects fish location and feeding activity. Rising tide pushes water into the shallow flats, bringing baitfish and predators with it. This is prime time for sight-casting and shallow-water fishing. Falling tide concentrates fish in deeper channels and holes, making those areas more productive.

The bay experiences a semi-diurnal tide (two highs and two lows per day) with a range of 1 to 2 feet. Slack tide—the brief period between rising and falling—is often slow because fish are not pushed by current. Plan your fishing around the tide tables published by NOAA; a rising tide in the morning or late afternoon usually produces the best bite.

Frequently Asked Questions

What is the best time of year to fish Redfish Bay?

Fall (September through November) and spring (March through May) are the most consistent seasons. Water temperatures are moderate, baitfish are abundant, and redfish move into shallow flats to feed. Winter is slower but still fishable in deeper channels, and summer is the slowest season overall.

Can I wade Redfish Bay, or do I need a boat?

Wading is productive and popular because much of the bay is 3 to 5 feet deep with firm bottom. Wade on incoming or high tide when water depth allows free movement. A boat covers more water and works better in low-tide or murky conditions, but either method can be effective.

What size redfish should I expect to catch?

Redfish in Redfish Bay average 22 to 26 inches, with many fish in the 24- to 28-inch range. The slot limit (18 to 28 inches) protects larger spawning fish, so most keepers fall in the mid-20s. Sight-casting often produces larger fish than blind-casting.

Do I need a guide to fish Redfish Bay?

No, but a guide can accelerate your learning curve, especially if you are new to shallow-water sight-casting or unfamiliar with the bay's structure. Many guides operate out of Rockport and Fulton and charge $300 to $500 per day for two anglers.

What happens if I catch a redfish over 28 inches?

Fish over 28 inches must be released immediately. The slot limit protects large spawning redfish. Handle the fish carefully, keep it in the water as much as possible, and release it headfirst into deeper water to help it recover.
