Aquaculture Already Feeds More of the World Than Fishing Does. Can Your Farm Keep Up?

Aquaculture has overtaken wild-caught fishing as the primary source of aquatic protein — and as global demand for animal protein keeps rising, that gap will only widen.

More fish, more shrimp, more scale. But is farming capacity actually keeping pace with what that scale demands? Water quality, feed management, environmental control, and disease pressure all compound faster than most operations can adapt to them.

At HUADE, we start with what most feed strategies overlook: the gut itself.

Antimicrobial peptides are one of the directions the industry is exploring to address this, and some producers report positive results from their use. But consistent trial evidence is harder to generate in aquaculture than in land animals — water chemistry, species, and rearing conditions all interact in ways that make controlled testing difficult.

At HUADE, our aquaculture work today is centered on what we can prove: intestinal development, and its direct, measurable effect on growth performance.

Intestinal Development
In Fast-Growing Systems, the Gut Is the Bottleneck

Aquaculture production cycles are short and stocking densities are high. Feed moves fast, and how much of it actually gets absorbed — not just consumed — is what decides growth

Unlike mammals, fish don't have finger-like villi lining their intestine. Absorption depends instead on broad mucosal folds along the intestinal wall — the more developed those folds, the more surface area available to absorb nutrients from the same feed input.

EGFR signaling — the pathway that drives this kind of intestinal development — is conserved across vertebrates, including fish, though fish carry their own duplicated version of the receptor as part of their evolutionary history. That shared foundation is what allows recombinant EGF to support intestinal development directly.

In a 10-week commercial trial on Pacific white shrimp, animals receiving Tipek showed intestinal length increase by 0.5 cm over the control group. In a 30-day trial on largemouth bass, Tipek increased intestinal length by 3.2 cm — an 18.5% improvement over control. That's a directly measurable expansion of the tissue responsible for nutrient absorption, not just a theoretical mechanism.

Mucosal Repair
High-Density Rearing Doesn't Give the Gut Time to Recover

Transport stress, sudden feed transitions, fluctuating water quality, and high stocking density all place continuous pressure on the intestinal barrier. Once the tight junctions between epithelial cells weaken, permeability increases — and performance can decline before any visible disease appears 

EGF is naturally secreted along the gastrointestinal tract and is normally replenished quickly. Under stress, that natural replenishment can fall behind. Supplementing recombinant EGF is designed to help restore that balance when animals need it most.

Aquaculture Performance
Gut Development Shows Up Directly in the Numbers

In a 10-week trial on Pacific white shrimp in Zhangzhou, Fujian, shrimp fed Tipek at 1,000 g/t — starting from a slightly lower average body weight than the control group — reached 1.83 g higher final body weight, with survival rate up 3.9 percentage points and feed conversion ratio improved by 0.14.

In a 30-day trial on largemouth bass in Chengdu, Sichuan, fish fed Tipek at 500 g/t gained 17.8 g more final body weight than the control group — an 11.2% improvement — with body length up 8.3%, daily feed intake up 16.1%, and feed conversion ratio improved by 0.08.
