# Nets & Traps

Nets & Traps bundles three unrelated jobs: landing a hooked fish, throwing a net over live bait, and leaving a trap for crab, crawfish or lobster. Each has its own build — a soft mesh protects a fish you'll release, a cast net's mesh size decides what bait it keeps, and a trap's style decides what you can leave unattended.

## How it works

Nets and traps work by sizing an opening to the catch, then giving it no way back through. A landing or dip net is a mesh bag on a rigid hoop, swung or scooped by hand to lift a fish or bait already within reach. A cast net is a flat weighted circle, thrown open so it sinks over bait before the fish scatter; pulling the retrieve rope draws its reinforcing lines shut into a bag. A trap is left in the water baited inside a cage or cylinder, with a funnel-shaped entrance the catch can swim or crawl into easily but can't find again from the inside. Across all three, the mesh or funnel opening is the one spec that decides what's kept and what slips through, which is why mesh size and hoop size matter more than material or brand. [12] [14] [13]

| Family | What it is | Suits |
|---|---|---|
| Landing or dip net | A mesh bag on a rigid hoop and a handle, controlled by hand to lift a hooked fish or scoop live bait from the water. | Anglers landing a fish already hooked, or scooping baitfish and bait by hand. |
| Cast net | A flat circular net rimmed with lead, thrown open by hand; it sinks over bait and cinches shut on retrieve. | Catching live baitfish and shrimp before fishing, not for landing a hooked fish. |
| Trap | A cage, cylinder or hoop net left baited in the water for minutes to hours, with a one-way funnel entrance. | Crab, crawfish, shrimp, minnows and recreational lobster. |

1. **What it's for.** Landing a fish or bait by hand, casting a net, or trapping?
   Routes to three product families that share almost no facets; nothing else is worth asking before this.
   If Landing or dip net: ask Mesh feel, Hoop size, Net (bag) depth, Handle length, Handle style; skip Mesh size, Net radius, Lead per foot, Target catch, Trap build, Trap material, Degradable escape panel.
   If Cast net: ask Mesh size, Net radius, Lead per foot; skip Mesh feel, Hoop size, Net (bag) depth, Handle length, Handle style, Target catch, Trap build, Trap material, Degradable escape panel.
   If Trap: ask Target catch, Trap build, Trap material, Degradable escape panel; skip Mesh feel, Hoop size, Net (bag) depth, Handle length, Handle style, Mesh size, Net radius, Lead per foot.

2. **Mesh feel.** Releasing the fish, or keeping it?
   Only matters once a hand net is chosen; release favours soft mesh, keeping doesn't need it.

3. **Mesh size.** Netting small bait (shrimp too), medium, or big bait?
   Mesh size sets the smallest bait a cast net keeps; it decides the model before radius or weight do.

4. **Target catch.** Crab, crawfish, shrimp or minnows, or lobster?
   Sets the trap's whole shape and size; a crab pot and a minnow trap share no parts.

## What to surface

### What it's for

Whether it's a net you hold to land a fish or scoop bait, a net you throw to catch bait, or a trap left in the water for crab, crawfish, minnows or lobster. These solve different jobs, so almost nothing else in this register applies to more than one of them. Knowing which of the three a buyer wants removes everything built for the other two before a single spec gets compared. [11] [12] [14]

Values: Landing or dip net, Cast net, Trap.
Question to ask: Landing a fish or bait by hand, casting a net, or trapping?

Used as: top-level split. Data: on the listing, backfill cost none. Look for it as: The title and category breadcrumb almost always say which of the three it is.
Near-universal from the title alone.
Chart: Catch method map.

### Target catch

Which animal the trap is built for: crab, crawfish, shrimp or minnows as bait, or recreational lobster. A crab trap, a minnow trap and a lobster hoop net look nothing alike and aren't interchangeable, so this decides the trap's whole shape, size and the rules that govern it before anything else does. [11] [3] [10]

Values: Crab, Crawfish, shrimp or minnows, Lobster.
Question to ask: Crab, crawfish, shrimp or minnows, or lobster?

Used as: top-level split. Data: on the listing, backfill cost none. Look for it as: Stated directly in the title ('Crab Trap', 'Minnow Trap', 'Lobster Hoop Net').

### Mesh size

The width of one diamond opening in a cast net's mesh, measured stretched corner to corner, given in fractions of an inch. Mesh size sets the smallest bait the net keeps and the biggest hole a small fish slips through, so it has to match the target bait before weight or radius matter. Some states also cap how fine a recreational cast net's mesh may legally be. [4] [5] [7] [9] [6] [8]

Values: 3/8 in or finer (1 to 5 in bait, shrimp included), 1/2 in (5 to 10 in bait), 1 in or larger (12 in and up bait).
Question to ask: Netting small bait (shrimp too), medium, or big bait?

Used as: top-level split, filter. Data: on the listing, backfill cost low. Look for it as: In the title or a model-number table ('1/2" Mono'), not always a structured spec field.
Brand spec tables carry it reliably; where missing, the model name (e.g. '300 Series') maps to one mesh via the brand's own table. Promar's own wider lineup (checked beyond the two originally cited models) shows 3/16, 1/4 and 3/8 in all targeting the same 1-5 in bait, and 1 in and 1-3/8 in both targeting 12 in-and-up bait, so the tiers below follow the brand's real bait-size breaks rather than one mesh fraction per tier.
Chart: Mesh size to bait size.

### Mesh feel

Whether the netting is soft rubber or knotless nylon, or ordinary knotted nylon with a hard knot at every crossing. A knot is a hard, abrasive point; rubber and knotless mesh have none, so they strip less slime and fewer scales off a fish you plan to release. Knotted nylon is cheaper and tougher against hooks, which is fine once the fish is going in the cooler. [1] [16]

Values: Rubber or knotless, Knotted nylon.
Question to ask: Releasing the fish, or keeping it?

Used as: top-level split, filter. Data: on the listing, backfill cost low. Look for it as: A bullet point ('knotless', 'rubber mesh') rather than a spec table; sometimes only visible in the product photo's mesh texture.
Brand copy calls out 'knotless' or 'rubber' when present; its absence usually means ordinary knotted nylon.

### Handle style

Whether the handle is fixed, telescoping or sliding to extend, folds for storage, or there's none at all (a hoop you hold by the rim). A telescoping or sliding handle lets one net cover a kayak's short reach and a dock's long one, which a fixed handle can't; a folding handle trades that reach for a shorter item to stow. [1]

Values: Fixed, Telescoping or sliding, Folding, Handle-free.
Question to ask: Fixed, telescoping, folding, or no handle?

Used as: shown on the card, filter. Data: on the listing, backfill cost low. Look for it as: Frabill's own site is organized by this exact field (fixed, folding, sliding, telescoping, handle-free); only confirmed on that one brand's taxonomy, so other brands' or marketplaces' listings may only hint at it in bullet copy rather than a labeled field.

### Trap build

The trap's shape and whether it folds: a rigid pyramid or box, a collapsible star or ring trap, or a two-piece cylindrical (torpedo) trap. A collapsible trap folds flat for a trunk or kayak hatch; a rigid pyramid or box trap of the same footprint usually holds more catch and survives rough handling better. Torpedo traps are sized for bait, not table fare. [10] [3]

Values: Rigid pyramid or box, Collapsible or star, Torpedo (two-piece cylinder), Hoop or ring.
Question to ask: Rigid trap, or one that folds flat?

Used as: shown on the card, filter. Data: on the listing, backfill cost low. Look for it as: Clear from the title and the product photo ('collapsible', 'folding', 'pyramid').

### Net radius

How far the net spreads open when thrown, measured from the centre to the rim. A bigger radius covers roughly the square of the increase in water per throw, but takes more strength and practice to open fully and needs water at least as deep as its radius. [13] [4] [5]

Range: 3 to 12 ft. Most recreational throws use a 4 to 8 ft net.
Question to ask: Throwing a small net, or a big one?

Used as: filter, sortable. Data: on the listing, backfill cost low. Look for it as: In the model table ('4 ft', '6 ft') rather than a single numeric field.
Chart: length on a horizontal scale.

### Handle length

How far the net reaches from hand to hoop. A short handle is light and stores small but needs the angler to lean over the gunwale; a long handle reaches down from a dock or a drifting boat without leaning, at the cost of swing weight and storage length. [1] [2]

Question to ask: How long a reach do you need?

Used as: shown on the card, filter, sortable. Data: on the listing, backfill cost low. Look for it as: In the title or bullets on most listings; already a field in the add-on's sizing block.

### Trap material

What the trap's cage or mesh is made of: galvanized steel wire, vinyl-coated wire, stainless steel, or plastic-coated mesh. Plain galvanized wire rusts fastest in saltwater and is the usual material on the cheapest crab and minnow traps; vinyl-coated and stainless versions cost more but last seasons longer in salt or brackish water. [3] [10]

Values: Galvanized steel, Vinyl-coated wire, Stainless steel, Plastic-coated mesh.
Question to ask: Plain galvanized, coated wire, or stainless?

Used as: shown on the card, filter. Data: on the listing, backfill cost low. Look for it as: In the title or bullets ('galvanized steel', 'vinyl coated'); rarely a dedicated spec field.

### Hoop size

The width and length of the rigid frame that holds a landing or dip net's mesh bag open, given as two numbers. A hoop much narrower than the fish won't scoop it on the first try, and a hoop far bigger than needed is heavier and clumsier to swing one-handed, so it should roughly match the biggest fish the net will land. [2]


Used as: shown on the card, filter. Data: on the listing, backfill cost medium. Look for it as: A feature bullet like 'Hoop Size: 14" x 18"', rarely a structured field.
Stated as an exact number only on brand spec pages (one brand, one model, backs the figure here); generic retail listings usually drop it to a vague 'large/medium' size tier, so filling it in needs a brand-page lookup, not a listing scrape.

### Net (bag) depth

How far the mesh bag hangs below the hoop, which is how much of the fish stays below the surface once netted. A shallow bag lets a big, thrashing fish flip back out over the rim; a deep bag holds it but is slower to free a hook from. Depth is usually sized to the hoop rather than chosen on its own. [2]


Used as: shown on the card. Data: on the listing, backfill cost medium. Look for it as: A feature bullet ('Net Depth'), rarely in a structured spec table.
Only stated on brand pages that bother to list it; infer 'deep enough' from hoop size otherwise.

### Lead per foot

How much lead weight is sewn around the net's rim for every foot of its size rating. More lead per foot sinks the net faster over fast-moving or deep bait, but adds weight that still has to be thrown the same distance, which is why the heaviest nets are sold in the biggest radii, not the smallest. [4] [5] [13] [7] [8]

Range: 0.75 to 1.35 lb/ft. Most standard nets run close to 1 lb per foot; Promar's heavier Pro Series nets (checked beyond the two originally cited models) run up to about 1.35.

Used as: shown on the card, sortable. Data: on the listing, backfill cost medium. Look for it as: In bullet copy ('1 lb of actual lead weight per foot'), not a structured spec field.
Stated on brand spec pages for mid-tier nets and up; cheap nets often omit it.

### Degradable escape panel

Whether the trap has a panel, fastener or twine built to rot away within weeks so a lost trap stops trapping on its own. A lost or abandoned trap without this feature can keep catching and killing for years; many places that allow crab and lobster traps require some version of it, though which fastener and timeframe counts varies by jurisdiction. [15]


Used as: shown on the card. Data: needs research, backfill cost high. Look for it as: Essentially never stated on a retail listing; sometimes visible in a product photo as a wood panel or a differently coloured twine section.
Needs a read of the product photo or the manufacturer's own compliance notes, and the rule itself should be looked up per jurisdiction rather than assumed from the product. Realistic only for the top of the catalog.

## Numbers worth computing

| Metric | Formula | Why |
|---|---|---|
| Coverage per throw (sq ft) | `pi * radius^2` | Doubling a cast net's radius throws over four times the water, which is the real trade against the weight and skill a bigger net takes to throw well. [13] |

## What you give up

- Rubber-coated and knotless mesh protect a released fish's slime coat and resist snagging trebles, but they cost more and feel stiffer than plain knotted nylon, which is fine once you're keeping the catch anyway. [1] [16] Board branch: "See more conservation nets".
- A finer mesh keeps smaller bait and shrimp, but a tightly woven net catches more water on the throw and sinks slower for its weight, and in some states a cast net can't legally be that fine. [4] [13] Board branch: "See more fine-mesh bait nets".
- A collapsible or star trap folds flat for a trunk or a kayak hatch, but a rigid pyramid or box trap of the same footprint usually holds more catch and survives rough handling better. [10] [3] Board branch: "See more packable traps".

## How to draw it

**Mesh size to bait size** (scale, shows Mesh size). Lines up each common mesh size against the bait length it's built to catch, so a buyer sees at a glance whether 3/8 or 1/2 inch matches what they're after. This is a proposal, nobody draws it this way yet. [4] [5]

**Catch method map** (two axis map, shows What it's for). Plots active tools you throw or scoop against passive ones you leave behind, and fish against bait or shellfish, so it's clear why a landing net and a crab trap share a category but nothing else. This is a proposal, nobody draws it this way yet.

## Words you will meet

- **Stretched mesh**. The size of one net opening measured corner to corner on the diagonal when pulled taut, the convention regulators use to set legal mesh limits.
- **Knotless mesh**. Netting woven without a knot at each crossing, leaving no hard, abrasive point against a fish or bait that touches it.
- **Gilling**. When a fish or baitfish's gill cover catches in the mesh and it can't back out, which stiff monofilament causes more than soft nylon.
- **Torpedo trap**. A two-piece cylindrical trap, usually for minnows or crawfish, that unclips in the middle to load bait and dump the catch.
- **Braille line**. The reinforcing cord sewn in rings across a cast net that cinches the net shut when the retrieve rope is pulled.
- **Slime coat**. The mucus layer on a fish's skin that fights infection and is scraped off by a rough net, lowering a released fish's odds.
- **Escape panel**. A section of a trap, often wood or untreated twine, built to rot away within weeks so a lost trap stops trapping.
- **Lead per foot**. How much lead is sewn around a cast net's rim for each foot of its size rating, which decides how fast it sinks.
- **Hoop size**. The width and length of the rigid frame that holds a landing or dip net's mesh open, usually given as two numbers.

## Where we made a call

- Knotless or rubber mesh is gentler on a released fish's slime coat than ordinary knotted nylon. (confidence high). A brand markets this directly and an independent catch-and-release primer recommends rubber-coated or dense mesh over standard mesh for the same reason. [1] [16]
- Some states cap how fine a recreational cast net's mesh may legally be. (confidence medium). Sourced to one state's example (Florida, 1 inch in fresh water) via an encyclopedia summary; could not confirm a second state's figure or reach the regulation text directly. [13]
- About 1 lb of lead runs along each foot of a cast net's rim. (confidence high). A manufacturer's own spec sheet and an independent primer give the same figure; lighter nylon nets for small bait run a little under it. [5] [13]
- Many places that allow crab or lobster traps require a panel or fastener that rots away within weeks. (confidence medium). Sourced to one encyclopedia summary of state rules; the underlying regulation text, and which states, could not be confirmed this session. [15]
- Nylon multifilament cast-net mesh is softer on live bait than monofilament mesh. (confidence medium). One brand's own two product lines state this; no independent source was reached to confirm it as a general rule. [4]
