| Marine source declaration |
Confirms whether the product is squid-derived, squid-flavored, hydrolysate-based, or a formulated marine attractant blend. |
Source material, origin, species or raw-material description, and supplier declaration. |
| Active attractant profile |
Determines the product's practical value for feed attraction and palatability. |
Peptide, amino acid, soluble fraction, nucleotide, betaine-like component, or flavor-profile information where available. |
| Protein or peptide level |
Useful when the product is hydrolysate-based or positioned as a marine peptide attractant. |
Crude protein, peptide level, degree of hydrolysis, amino nitrogen, or amino acid profile if available. |
| Physical form |
Affects dosing, mixing, coating, extrusion, dusting, and handling. |
Powder, granule, liquid, coated powder, carrier-based blend, bulk density, and appearance. |
| Water stability |
Aquafeed attractants must remain effective long enough for feed detection and intake without excessive leaching. |
Water-stability guidance, leaching data, recommended coating method, or application timing. |
| Heat and extrusion tolerance |
Processing can reduce volatile flavor value or change active fractions. |
Pelleting, extrusion, drying, coating, or post-application guidance from the supplier. |
| Odor intensity and consistency |
Strong marine odor can affect palatability, warehouse handling, cross-contamination risk, and batch consistency. |
Odor description, sensory profile, batch consistency data, and storage guidance. |
| Carrier system |
Carrier affects active concentration, flowability, mixing, label declaration, and cost per active unit. |
Carrier type, feed-grade declaration, carrier percentage, allergen status, and GMO statement where required. |
| Salt and ash |
Marine ingredients can contribute salt and ash that may affect formulation limits and osmoregulation-sensitive diets. |
Salt, ash, mineral profile, and sodium or chloride levels when relevant. |
| Microbiological quality |
Important for aquafeed safety, export approval, and customer audits. |
Total plate count, yeast and mold, Salmonella, E. coli, coliforms, Vibrio where required, and other requested parameters. |
| Heavy metals and marine contaminants |
Marine-source products may require additional checks for feed safety and import approval. |
Lead, arsenic, cadmium, mercury, dioxins, PCBs, histamine where relevant, and other buyer-specific contaminant limits. |
| Regulatory suitability |
Permitted use, species claims, origin declarations, and import requirements differ by destination market. |
Feed-grade declaration, origin statement, market-specific compliance documents, and label guidance. |
