The State of Fishing in Port Aransas
A historical, data-driven look at the Port Aransas fishery: when target species show up across the year, decades of Deep Sea Roundup tournament weights, and the shape of the local charter fleet — built on real occurrence records and published results, never a bite forecast.
Fishing is not a pastime in Port Aransas — it is the reason the town exists in the shape it does. The jetties, the ship channel, the shallow back bays behind Mustang Island, and the blue water a few miles past the beach have drawn anglers here for more than a century, and the calendar of the island still runs on the calendar of the fish. This report is an attempt to describe that fishery the way a data journalist would: not with hot tips or a forecast for the weekend, but with the historical record of what actually shows up here, when, and how big it gets.
It is deliberately a different animal from our Weekly Fishing Report, which covers live conditions — the wind, the tides, and the fronts moving through this week. This is the long view: a statistical and historical portrait built from three real, citable sources. The first is decades of species occurrence records compiled by the Global Biodiversity Information Facility (GBIF), pulled for the Aransas Bay and Port Aransas nearshore Gulf area and broken out by month, so you can see the seasonal rhythm of each target species from the record itself. The second is the published results of the Deep Sea Roundup — Texas' oldest saltwater fishing tournament, held in Port Aransas since 1932 — from which we take the winning weight for each species in recent years. The third is a simple, aggregate count of the local charter fleet, broken down by the kind of trip each operator runs.
A word on what this report will never do. It contains no predictions and no fishing advice. It will not tell you that the trout will be biting on a particular lure, or that next month is "going to be good." Every number below is a real, dated figure traced to its source; where a source is silent, we leave the gap rather than fill it with a guess. The seasonal patterns are drawn strictly from when species have been historically recorded in the area — a description of the past, not a promise about the future. Fish move with weather, water temperature, bait, and luck, none of which a chart can foretell. What the data can do is give you an honest, sourced baseline: the shape of the fishery, distilled from the record.

The fishery, month by month
Each line traces one bay species' seasonal signal: the share of all its recorded occurrences in the Aransas Bay area that fall in a given month. Plotting share rather than raw counts controls for the fact that some species are simply logged more often than others, so the curves read as relative seasonal presence. The pattern that emerges is the one Coastal Bend anglers know in their bones — a build through spring, a genuine peak around the shoulder months of late spring and fall, and a quieter winter — but here it is drawn from the record rather than remembered.

Peak months by target species
The table below lists, for each target species, the three months in which it has been recorded most often in the area. Read it as "historically, this is when this fish is most present," not as a prediction for any particular season.
| Species | Water | Peak months (by record) | Records |
|---|---|---|---|
| Atlantic CroakerMicropogonias undulatus | bay | Apr · May · Oct | 21,878 |
| Spotted SeatroutCynoscion nebulosus | bay | May · Sep · Oct | 15,491 |
| Southern FlounderParalichthys lethostigma | bay | Apr · May · Oct | 15,280 |
| Black DrumPogonias cromis | bay | May · Sep · Oct | 14,869 |
| Red Drum (Redfish)Sciaenops ocellatus | bay | May · Sep · Oct | 14,777 |
| SheepsheadArchosargus probatocephalus | bay | May · Sep · Oct | 14,729 |
| Red SnapperLutjanus campechanus | offshore | Jun · Jul · Nov | 118 |
| King Mackerel (Kingfish)Scomberomorus cavalla | offshore | Jun · Jul · Aug | 61 |
| Cobia (Ling)Rachycentron canadum | offshore | Jul · Aug · Sep | 48 |
| Great BarracudaSphyraena barracuda | offshore | Jul · Sep · Oct | 19 |
Not a prediction. "Peak months" reflect when a species has historically been documented in the area across all available years of occurrence records — a description of the past. They are not a forecast of when, where, or whether fish will bite in any given season, and no lure, bait, or technique is implied.
Deep Sea Roundup, by winning weight
The Deep Sea Roundup is the longest-running saltwater tournament in Texas, and its official results are a rare public, decades-deep record of what large fish are actually landed out of Port Aransas. Below are the winning (first-place) weights by species for the most recent years published. These are documented tournament results — real fish, weighed on a certified scale — not estimates.

| Species | 2023 |
|---|---|
| White Marlin | 100 lb |
| Shark | 73.6 lb |
| Ling | 70.4 lb |
| Sailfish | 70 lb |
| Wahoo | 44.8 lb |
| Barracuda | 36.3 lb |
| Kingfish | 33 lb |
| Jackfish | 22.9 lb |
| Blackfin Tuna | 20.5 lb |
| Red Snapper | 19.1 lb |
| Dolphin | 10 lb |
| Red Drum | 9.6 lb |
| Bonito | 9.2 lb |
| Black Drum | 9 lb |
| Redfish | 6.3 lb |
| Flounder | 5 lb |
| Gafftop | 4.5 lb |
| Spotted Sea Trout | 4.1 lb |
| Mackerel | 2.8 lb |
A dash means that species was not among the weighed first-place entries in that year's published results — not that none were caught. Winning weights vary year to year with conditions, entries, and rules.
The charter fleet, by trip type
A charter is how most visitors actually get on the water here, so the shape of the fleet is part of the state of the fishery. The counts below are an aggregate snapshot of the licensed charter operators in our directory, sorted by the kind of trip they run — bay and inshore, offshore and deep-sea, or both. No operator is named or ranked; this is fleet structure, not a buyer's guide.
3
operators running Gulf trips
0
operators running bay trips
6
operators running both
Sample size: 9 charter operators, captured July 15, 2026. We deliberately do not publish per-trip dollar price ranges: no verifiable public dataset of charter prices exists for Port Aransas, and inventing one would violate our no-fabrication policy. When we field a dated price survey with a disclosed sample size, aggregate ranges will appear here. Trip type is inferred from each operator's own description. Browse the charter directory.
