💡 Girth Measurement Tip: Measure girth at the widest point of the fish body (typically just behind the pectoral fins). For most species, girth is approximately 55–65% of body length. If you didn’t measure girth at catch, use the species average ratio as an estimator.
💡 Wall Space Planning Tip: Always add at least 4–6 inches of clearance on each side of the panel when planning wall space. For mounts over 36 inches, use two wall studs or heavy-duty toggle anchors rated for at least 2× the mount weight. Fiberglass and urethane reproductions are the lightest options for large fish.

Getting a replica mount of a trophy fish helps to recall a big catch without having to keep the fish. A replica is an artificial copy of a fish, that looks almost the same as the real thing. The finished mount seems extremely natural and alive rather than dead and mounted.

Professional fiberglass copies are formed from precise molds and hand-painted by expert artists to match the right size color and markings.

How to Get a Fish Replica Mount

Size matters a lot when ordering a replica. Some companies produce more than 4000 molds for fish replicas of various species and sizes. Empty fiberglass forms are available for most kinds of fish, for instance trout between 20 and 36 inches, bass of all sizes and walleye up to 16 pounds.

Copies of largemouth bass come in lengths of 10 to 29 inches. There are also bigger options, like a half-sided mount of a 58-inch sailfish or a 36-inch nortehrn pike replica. A realistic half mount striped bass comes in at around 43 inches.

To get a replica made, send pictures of the fish together with details like tip-to-tip length or weight. Length and girth are the key details. Measuring your hand and placing it across the fish body, you can estimate the size.

Weight matters little, because length and girth matter more. Some taxidermists work extremely carefully, even copying individual scales, but that costs much moor.

Prices run around 15 dollars per inch of fish, or more for a quality mount, depending on species and size. A replica commonly doubles the cost of a skin mount… Like, 10 versus 20 dollars per inch.

Shipping can match the price itself depending on size, so local specialists help to save money and time. For instance, a 92-inch sailfish replica cost 1550 dollars with shipping.

Sometimes the replica does not entirely match the original. You caught a 28 and a half inch fish, but the closest replica had 29 inches. Another model was 24 and a half inches, but with a girth of 20 and three-quarter inches; thicker than the real fish.

Although not perfectly exact, good painting still makes it look great.

Simple care keeps the mount nice: keep it dusted and away from direct sunlight. Mounts from decades ago commonly stay fresh looking after 40 years. Because of the quality and price of replicas today, there really is no good reason to keep a trophy fish just to haveit mounted.

All salt and freshwater species are available.
