"Match the forage" is the most repeated advice in bass fishing and the least explained. It does not primarily mean color. It means matching size, profile, depth, and behavior — in that order — of whatever the bass in front of you are actually eating, with color a distant last input. This chapter covers the forage cast of NC reservoirs: what each species looks like, where it lives through the year, and what it tells you to tie on. Because here's the working truth of the Seasonal chapter's second rule: the bass's calendar is really the forage's calendar.

Threadfin Shad — The Main Course

ID: Small — mostly 2–4 inches — silver with a distinct yellow-tinted tail and a dark shoulder spot. Travel in large, tight schools that flicker and dimple the surface. If you see rain-like flickers on a calm morning, it's threadfin.

Where and when: Open-water roamers that follow plankton: main lake and creek mouths most of the year, flooding into the creek arms in fall (the migration that drives the entire fall pattern), spawning at first light in late spring against hard edges — riprap, seawalls, grass — which is the shad spawn event from the Seasonal chapter. Cold-sensitive: prolonged water under about 42°F kills them, and winter die-offs concentrate every predator in the lake on the dying, fluttering ones.

What it means: The default forage, and the reason the default moving-bait profile is a 2.5–3.5" silver flash. When bass are on threadfin: smaller crankbaits, lipless baits, underspins, walking baits, and swimbaits in shad patterns — and downsize in fall, when the young-of-year run small. In a winter die-off, anything that flutters and dies on the fall is dinner.

Gizzard Shad — The Big-Fish Meal

ID: Threadfin's oversized cousin — starts small but grows to 12+ inches, deeper-bodied, silver-blue with no yellow tail. Schools looser and often deeper than threadfin.

What it means: Gizzards are why big baits catch big fish on NC reservoirs. A 5–7 inch profile — big glide, magnum spoon, oversized swimbait, plopper — imitates a meal only the better fish bother chasing. When your graph shows big single marks shadowing loose bait rather than tight balls, think gizzards and size up.

Blueback Herring — The Game-Changer Where Present

ID: Sleeker and faster than shad — 4–6 inches, slim, blue-backed and chrome-sided. Present in Kerr and Gaston among the site's waters, and their presence changes how the bass behave.

Where and when: Herring are pelagic sprinters that live over open water and deep structure, and they spawn in late spring on main-lake hard spots — points, sandbars, clay bars — in short dawn flurries, pulling big postspawn bass out to the main lake right when the textbook says fish should be in the pockets.

What it means: On herring lakes, bass roam more, suspend more, and school on the surface over open water more — fish that follow the bait instead of holding on cover. The playbook: fast, erratic, and long-casting. Walking baits and pencil poppers burned over points, flukes and jerkbaits worked fast, swimbaits over open water — and a topwater rigged and ready all day, because herring-lake schooling can erupt anywhere, anytime, for ninety seconds. The hi-vis yellow braid topwater setup earns its keep here.

Bluegill and Sunfish — The Resident Forage

ID: The bream family — bluegill, redear, pumpkinseed — deep-bodied, green-gold-orange, living their whole lives around shallow cover.

Where and when: Wherever the cover is: docks, laydowns, grass. Their headline event is the bed colonies — honeycomb clusters of light circles in pockets from late May through summer — which pull the biggest postspawn females shallow to raid them. Bluegill are also the primary forage of the resident shallow bass population year-round; where shad roam, bream stay home.

What it means: Compact, flat-sided, green-and-gold: green pumpkin everything, bluegill-pattern squarebills and wake baits, and the frog and bug-bait guides' warm-water work around cover. Around active bream beds, a weightless soft stickbait or a popping frog across the colony is as close to a guarantee as this sport offers.

Crayfish — The Bottom Contract

ID: You'll rarely see the animal itself — you infer craws from habitat: rock, gravel, riprap, hard clay, and chunk-rock banks. Colors run brown-green most of the year, shifting toward red-orange in the pre-molt periods of early spring.

Where and when: Year-round on hard bottom, and most important exactly when shad matter least: late winter and early spring, when 45–55°F water has bass rooting rock for the biggest, slowest calories available — the season red lipless baits and orange-bellied crankbaits were invented for.

What it means: Every bottom-contact presentation on this site is on the craw contract — jigs with craw trailers, Texas-rigged creatures, football jigs dragged on the transitions from the Structure & Cover chapter. Match the seasonal color drift: red-orange accents in early spring, green pumpkin and brown the rest of the year. A bass that spits up craw parts in the livewell has told you the day's pattern.

White Perch and the Rest of the Cast

• White perch — Abundant in Kerr especially: silver, deep-bodied, schooling over structure. Bass eat the young ones, and perch schools on your graph explain "fish" marks that never bite. A compact silver profile over deep structure covers it.
• Minnows and shiners — The shallow small-silver category; effectively covered by every small shad imitation.
• Frogs and amphibians — Seasonal shallow-cover forage; the reason the frog guides exist. Presence of actual frogs is a bonus, not a requirement — the frog is really imitating "something alive on the mat."
• Baby bass and other juveniles — Bass are enthusiastic cannibals; a bass-pattern jerkbait or swimbait is always a legitimate choice, especially postspawn when fry clouds are everywhere.

Reading Forage Sign on the Water

• Surface flickers and dimples — shad presence, and the tighter and more nervous, the more likely something is under them. "Nervous water" — a patch that shivers differently from the surrounding surface — is bait being herded.
• Birds are sonar with wings. Gulls and loons working in fall mark shad schools from a half-mile; a heron statue-still on a bank marks shallow bait; terns diving on a herring lake mark the school before it shows on your graph.
• On the graph: tight balls = threatened bait, loose haze = safe bait (per the Electronics chapter). Fish the threatened bait.
• In the livewell: spit-up tells the truth — craw parts, threadfin, a half-digested bluegill. Adjust to what the fish reports, not what you expected.

The Matching Framework

In order of importance:

1. Size. The number one variable, and the most commonly wrong. Fall bass gorging on 2" young-of-year threadfin will ignore a 5" bait swum through the school. Estimate the local forage size and match within an inch.
2. Profile and action. Slim and flashy for shad and herring; deep-bodied and compact for bream; crawling and clicking along bottom for craws. Behavior is part of profile — herring sprint, threadfin flutter, craws bolt backward.
3. Depth and location. Put the imitation where that forage actually lives — a bluegill pattern out on a main-lake hump imitates nothing.
4. Color — last. Get within the family (silver/white for shad, green-gold for bream, brown-orange for craw) and let the Water Clarity Guide pick the specific shade. Color is a clarity decision far more than a forage decision.
