The gafftopsail catfish (Bagre marinus) is found in the waters of the western central Atlantic Ocean, as well as the Gulf of Mexico and the Caribbean Sea. It has long, venomous spines which can cause painful wounds. It feeds on crustaceans and other fish. The male of the species fertilizes the eggs of the female, and broods them in his mouth until they hatch. The gafftopsail feeds throughout the water column. This fish is a common catch in the Southeastern US, although it may be found as far north as New York. They are considered strong fighters by anglers. They are taken from piers, jetties, reefs, and the surf, as well as bottom fishing or flats fishing. They are caught with hard lures as well as soft plastics, cut bait, and live or dead shrimp. Some fishermen use traps for catfish, a method regulated by some states.
Gafftopsail catfish live on the Atlantic, Caribbean and Gulf of Mexico coastlines from Cape Cod to Brazil.[1] They are also found in brackish waters, including estuaries, lagoons, brackish seas, and mangroves. Gafftopsails are generally common to abundant in their range.[1]
The gafftopsail catfish is blue-grey to dark brown with a light grey belly. Its appearance is typical for a catfish except for the deeply forked tail and the venomous, serrated spines. It also has a little hump that looks somewhat like a wave. The typical length of a mature gafftopsail catfish is about 17 in (43 cm). The anal fin is a few inches anterior to the tail and is white or pale blue, with 22–28 rays on it and a high, anterior lobe.[3] The pelvic fin is 6–12 in (15–30 cm) anterior to the tail fin. The gafftopsail catfish has maxillary barbels and one pair of barbels on the chin. It resembles the hardhead catfish, but its dorsal spine has a distinctive fleshy extension (like the fore-and-aft topsail of a ship).
The primary food of juveniles is unidentifiable organic matter; the secondary food is fish, with smaller amounts from other trophic groups. Unlike many other catfish, which are primarily bottom feeders, the gafftopsail catfish feeds throughout the water column. It eats mostly crustaceans, including crabs, shrimp, and prawns (95% of the diet), but it will also eat worms, other invertebrates, and bony fishes (about 5% of the diet).[4] In addition to humans, predators of the gafftopsail catfish include the tiger shark and bull shark.
Gafftopsail catfish spawn over inshore mudflats during a relatively short time span (10 days) from May to August;[5] they are mouthbreeders. The eggs are about 1 in (2.5 cm) in diameter. Males keep up to 55 eggs in their mouths until they hatch. Young are about 5 cm (2 inches) long when they hatch, and the male may continue to brood them until they are up to 4 in (10 cm) long. The males do not feed while they are carrying the eggs or young.[6]
The gafftopsail catfish is a common catch in the Southeastern United States, although it is also caught as far north as New York. They are taken from piers, jetties, reefs, and the surf, as well as bottom fishing or flats fishing. They are caught with cut bait and shrimp, or lures such as plugs, spoons and spinners, as well as soft plastic lures resembling shrimp, worms, and shad. They are attracted to the sound of struggling fish, like a popping cork creates. Catfish trapping is also used to capture them, but is regulated in some states. Catfish traps include "slat traps," long wooden traps with an angled entrance, and wire hoop traps. Typical bait for these traps includes rotten cheese and dog food.
Gafftopsail catfish are good eating; the red lateral line should be removed to prevent "muddy taste"; however in gafftopsails taken from southern Florida mangrove estuaries, this is seemingly unnecessary. The pectoral fins and dorsal fin contain venomous spines; care should be used when handling this fish.
The largest recorded weight for a gafftopsail catfish is 4.54 kg (10.0 lb)[7] and 69 cm (27 in) in length.[8] A more common weight and length of gafftopsails caught is 1–2 lb (450–910 g) and 12–16 in (30–41 cm).
As gafftopsail catfish grow longer, they increase in weight, but the relationship is not linear. The relationship between total length (L, in inches) and total weight (W, in pounds) for nearly all species of fish can be expressed by an equation of the form:
W = c L b {displaystyle W=cL^{b}!,} 
Invariably, b is close to 3.0 for all species, and the constant c varies between species.[9] Data from the Florida Fish and Wildlife Conservation Commission indicate, for the gafftopsail catfish, c = 0.000493 and b = 3.075[10] The relationship described in this section suggests a 12-inch gafftopsail catfish will weigh about one pound, while a 20-inch fish will likely weigh about five pounds.

Purjemerimonni (Bagre marinus) on noin 60 senttimetrin pituinen kala, jolla on leuassaan ja suupielissään lyhyt ja pitkä viiksipari. Selkäevä on korkea ja ensimmäinen eväruoto on pidentynyt rihmaksi. Rintaevien ensimmäinen ruoto taas on pitkä piikki, jossa on myrkkyä.[2]
Purjemerimonnien esiintymisalue kattaa Pohjois- ja Keski-Amerikan Atlantin puoleisen rannikon Cape Codista Panamaan. Niitä tavataan myös Meksikonlahdessa, ja joskus myös jokisuiden murtovedessä.[2]
Purjemerimonnin ruokavalioon kuuluvat pienet pohjassa elävät kalat ja äyriäiset, joita se löytää viiksiensä avulla.
Purjemerimonnit kutevat kesällä. Munia on 10–30 ja koiras ottaa ne hedelmöityksen jälkeen suuhunsa turvaan. Kuoriuduttuaan poikaset hakevat vielä usean viikon ajan turvaa isänsä suusta. Haudonnan aikana koiras ei syö mitään.[3]

De zeekatvis of gewone zeemeerval (Bagre marinus) is een straalvinnige vis uit de familie van christusvissen (Ariidae), orde meervalachtigen (Siluriformes).
De zeekatvis kan maximaal 69 cm lang en 4360 gram zwaar worden. Het lichaam van de vis heeft een langgerekte vorm en een voorste rug- en borstvin met lange, boogvormig oprijzende, giftige stekels. De staart is diepgevorkt. De kop is voorzien van een harde, benige beplating en zeer lange, afgeplatte baarddraden. De aarsvin heeft 22-28 vinstralen.
Het dieet van de vis bestaat hoofdzakelijk uit dierlijk voedsel. Hij voedt zich met macrofauna, kreeftachtigen en jaagt ook op vis. Bij bedreiging kan het dier de stekels op de vinnen overeind zetten en er behoorlijk pijnlijke steken mee toedienen.
De paaitijd duurt van mei tot augustus. De bevruchte eieren worden door het mannetje in de bek genomen en uitgebroed.
Deze zout- en brakwatervis komt voor in een subtropisch klimaat in het noordwesten, het westen en het zuidwesten van de Atlantische Oceaan, maar zwemt ook regelmatig riviermondingen binnen. De soort is voornamelijk te vinden in kustwateren (zoals estuaria, lagunes en brakke zeeën), getijdestromen, zeeën en ondiepe wateren (zoals mangroven, moerassen en ondergelopen grond). De diepte waarop de soort voorkomt is maximaal 50 m onder het wateroppervlak.
De zeekatvis is voor de visserij van aanzienlijk commercieel belang. Bovendien wordt er op de vis gejaagd in de hengelsport. Voor de mens is de zeekatvis gevaarlijk door de giftige stekels.
De soort komt niet voor op de Rode Lijst van de IUCN.
