About Jack Mackerel

Jack mackerel is a small Pacific oily fish used in pet food as a protein and omega-3 source, often a budget alternative to salmon.

Jack mackerel is an oily marine fish commonly used in dog and cat foods as a high-quality protein source and palatability enhancer, providing essential amino acids plus omega‑3 fatty acids (EPA and DHA), B vitamins, vitamin D and minerals like selenium. It can support skin, coat and joint health, but proper sourcing and processing are important to avoid histamine formation, rancidity or contaminant buildup, and it may trigger fish allergies in sensitive pets.

Why it's used

Jack mackerel delivers a high proportion of protein relative to fat and supplies useful amounts of the omega-3 fatty acids EPA and DHA, which formulators use to support skin, coat, and general anti-inflammatory nutrient goals. Its cost relative to salmon makes it an attractive fish protein option in mid-tier formulations.

Common concerns

  • Fish allergen Jack mackerel falls under the fish allergen group, relevant for pets with a documented fish sensitivity.
  • Histamine and freshness handling Like other oily pelagic fish, mackerel species are prone to histamine formation if not chilled and processed promptly after catch, because these species are naturally high in free histidine, which bacteria can convert to histamine, so prompt chilling and processing after catch is an important quality control point.

Also relevant

Canned jack mackerel is reported to provide a useful amount of omega-3 fatty acids, which is part of why it appears in fish-based recipes despite being less well known than salmon or tuna.
