Explore our export-ready, high-nutrition product catalogue manufactured in ISO and HACCP certified facilities for global distribution.
In the rapidly evolving global pet market, aquatic pet nutrition and high-protein companion animal diets have transitioned from basic sustenance to specialized, bio-engineered nutritional systems. Founded in 2024, Linyi Zesty Pet Trading Co., Ltd. stands at the forefront of China's advanced pet food manufacturing sector. Utilizing state-of-the-art twin-screw extrusion technology, micro-encapsulation, and freeze-drying infrastructure, we formulate and manufacture premium aquatic organism diets, tropical fish feeds, and specialized feline and canine nutrition for global B2B clients, importers, and brand owners.
Our operational architecture adheres strictly to global quality control benchmarks including ISO 22000, HACCP, BRCGS, and BSCI auditing frameworks. Every formulation undergoes micro-biological verification, heavy metal testing, and amino acid profiling before leaving our Shandong manufacturing nexus.
We provide full white-label and OEM solutions for global distributors. From micro-granules (0.5mm) for ornamental fry to floating pellet diets for koi and cichlids, freeze-dried raw animal snacks, and hypoallergenic wet feeds, our engineering team optimizes formulas for targeted digestibility, color enhancement, and growth performance.
The international aquatic pet industry is experiencing a paradigm shift. Modern aquarium enthusiasts and commercial aquaculturists no longer view fish food merely as basic organic meal. Instead, the demand centers on species-specific physiological nutrition, eco-friendly water-preservation pellets, and color-enhancing formulations containing natural carotenoids and astaxanthin.
Aquatic species exhibit distinct feeding behaviors across water columns: surface feeders (floating pellets), mid-water swimmers (slow-sinking granules), and benthic bottom-dwellers (fast-sinking wafers). Modern extrusion technology must guarantee uniform density and controlled buoyancy.
Leading global brands require high crude protein ratios (38% to 52%) derived from sustainable marine sources, krill meal, spirulina, and hydrolysed fish proteins. Addition of beta-glucans and MOS (mannan-oligosaccharides) significantly enhances aquatic immune defenses.
Standard feeds break down rapidly, causing nitrogenous waste spikes (ammonia and nitrites) that compromise tank filtration systems. High-tech vacuum spraying and binder selection prevent nutrient leaching and maintain pristine water transparency.

At Linyi Zesty Pet Trading Co., Ltd., our manufacturing setup is built around multi-stage industrial engineering. We combine double-screw thermal extrusion with low-temperature vacuum coating and freeze-drying technology.
Our extruders provide microscopic control over starch gelatinization and moisture density. By regulating barrel temperature profiles, moisture injection, and screw rotation speed, we produce uniform pellets ranging from 0.5mm micro-granules to 10mm pond sticks with pinpoint precision buoyancy.
Heat-sensitive micro-nutrients—such as beneficial probiotics, heat-labile vitamins (Vitamin C, B-complex), essential enzymes, and polyunsaturated fatty acids (Omega-3 & Omega-6)—are coated via post-extrusion vacuum spraying. This guarantees maximum biological activity without thermal degradation.
