Aquaculture Meat and Bone Meal

Updated: 2026-07-19

Overview

Meat and bone meal (MBM) is a rendered animal byproduct widely used in aquaculture as a cost-effective protein source. It is produced by cooking, drying, and grinding animal tissues unfit for human consumption, such as bones, offal, and carcasses. MBM is valued for its high protein content (50–60%) and balanced amino acid profile, making it a key ingredient in fish and shrimp feeds. In aquaculture, MBM helps reduce reliance on fishmeal, promoting sustainability. However, quality control is critical due to variability in raw materials and processing methods. Regulatory standards (e.g., EU, FDA) often govern its use to ensure safety and traceability.

Physical and Chemical Properties

MBM is a fine, granular powder with a light to dark brown color, depending on the raw materials and processing temperature. It is insoluble in water and has a density of approximately 0.5–0.7 g/cm³. The product is heat-treated to eliminate pathogens, ensuring microbiological safety. Chemically, MBM is rich in crude protein (50–60%), fats (8–12%), and minerals like calcium (7–12%) and phosphorus (4–6%). Its amino acid profile includes lysine and methionine, essential for fish growth. Ash content (20–30%) reflects its mineral density, but excessive ash may indicate lower protein quality.

Main Applications

MBM is primarily used in aquaculture feeds for species such as tilapia, catfish, and shrimp, where it partially replaces fishmeal to lower costs. It is also incorporated into livestock and pet foods. In aquaculture, MBM supports rapid growth and feed efficiency due to its high digestibility and nutrient density. Beyond feed, MBM serves as an organic fertilizer in agriculture, providing nitrogen and phosphorus. However, its use in ruminant feeds is restricted in many regions due to concerns over transmissible spongiform encephalopathies (TSEs).

Safety and Storage

MBM must be stored in a cool, dry environment to prevent moisture absorption and spoilage. Prolonged exposure to humidity can lead to mold growth or rancidity. Bulk storage silos should be cleaned regularly to avoid cross-contamination. Safety precautions include wearing dust masks and gloves during handling, as airborne particles may irritate respiratory systems. Although MBM is non-toxic, improper rendering or contaminated raw materials can introduce biohazards, necessitating strict supplier audits and compliance with hygiene standards.

B2B Procurement Guide

When procuring MBM for aquaculture, prioritize suppliers with certifications (e.g., GMP+, ISO 22000) to ensure quality and traceability. Key parameters to test include protein content (min. 50%), ash content (max. 30%), and contaminants like Salmonella or heavy metals. Prices vary by region and quality, typically ranging from $800–$1,200 per metric ton. Opt for long-term contracts with reliable producers to stabilize supply. For sustainability, inquire about the raw material sourcing (e.g., non-ruminant origins) and processing methods (low-temperature rendering preserves protein quality).
