What is the waste percentage for a fish market?

Starting a fish market comes with its own unique set of challenges, particularly when it comes to managing waste effectively. Understanding the factors that contribute to waste and learning how to manage them is essential for anyone starting this type of business.

What types of fish and seafood are sold at the market, and how does species variety affect waste levels?

Fish markets typically sell a wide variety of fish species including white fish (like cod and haddock), pelagics (like salmon and mackerel), tuna, shellfish (shrimp, mussels, prawns), and exotic varieties (such as sea bass and snapper). The variety of species significantly impacts waste levels, especially when dealing with species that have a higher perishability, such as fatty fish and shellfish.

Species that are more perishable or in peak seasonal surges are particularly prone to spoilage and waste. If the market does not have proper cold storage or handling systems in place, the loss can be substantial. Moreover, markets with diverse species face higher complexity in managing different storage conditions, which can also lead to increased waste.

What is the average daily or weekly volume of fish handled by the market?

The average volume of fish handled by a market can range from hundreds to thousands of kilograms per day, depending on the market size, location, and season. Larger wholesale markets can handle several metric tons of fish daily, with the volume fluctuating based on regional demand and species availability.

Market volume is also influenced by the local demand for specific fish species. For instance, during festive seasons or holiday peaks, the demand and supply may increase significantly, leading to more fish being brought to market, which in turn can result in higher waste levels.

What proportion of the fish delivered is discarded before reaching stalls due to spoilage, damage, or quality standards?

The percentage of fish discarded before reaching the stalls can range from 5% to 20%. This waste occurs due to spoilage, damage during transport, or failure to meet market quality standards.

Handling practices play a critical role in minimizing these losses. Fish that are improperly handled or not stored under the right conditions are more prone to spoilage. Markets with poor cold-chain infrastructure are more likely to experience higher discard rates.

What percentage of unsold fish remains at the end of a typical trading day?

On a typical trading day, about 5% to 15% of fish may remain unsold. This figure can vary based on market size, location, and the type of fish sold. When demand fluctuates or during seasonal downturns, the percentage of unsold fish increases.

During times of over-supply or when there is insufficient demand, unsold fish may need to be discarded, adding to the overall waste of the market.

How much waste comes from processing activities such as filleting, gutting, or trimming?

Processing activities, such as filleting, gutting, and trimming, generate significant waste. This waste can constitute anywhere between 30% to 60% of the initial fish mass, depending on the species and the types of cuts made.

Industrial-scale fish processing can lead to higher waste percentages due to the amount of non-edible parts produced. However, some of these by-products, like fish skins or bones, can be repurposed for other products, such as fishmeal or fertilizer.

What percentage of the discarded material is edible fish flesh versus non-edible parts like bones, scales, and guts?

In larger markets, about 15% to 30% of the discarded material consists of edible fish flesh, which includes trimmings and downgraded cuts. The remaining 35% to 50% is composed of non-edible parts such as bones, scales, and guts.

Non-edible parts, while not suitable for direct consumption, are valuable for secondary markets like fishmeal, fertilizer, or animal feed, which can help reduce the overall environmental impact of fish market waste.

How do seasonal variations in supply and demand influence waste percentages?

Seasonal variations play a significant role in fish market waste. During peak supply periods, when fish species are abundant, spoilage rates increase due to the sheer volume of stock coming into the market. Conversely, during low supply periods, waste can decrease, but prices may rise due to higher demand.

Over-supply during peak seasons is often a major contributor to waste. The colder months, when demand for certain fish species is lower, can also result in unsold fish at the end of the day.

What storage and cold-chain facilities are available, and how do they impact spoilage rates?

Cold storage and temperature-controlled transport systems are critical to reducing spoilage in fish markets. Well-maintained cold chains can cut spoilage rates in half compared to markets that rely on ambient storage practices.

Breakdowns in the cold chain can lead to rapid spoilage and increased waste. This is why fish markets need to invest in reliable refrigeration and ice storage systems to maintain fish quality and minimize losses.

How much of the waste is currently reused, repurposed, or sold for secondary markets (e.g., animal feed, fertilizer, fishmeal)?

Approximately 40% to 60% of fish processing waste is repurposed for secondary markets such as animal feed, fishmeal, and fertilizer. These by-products are valuable and can help reduce overall waste levels.

However, there are still significant quantities of fish waste that go unutilized, especially in markets lacking circular economy initiatives or proper infrastructure for waste repurposing.

What percentage of total waste is ultimately disposed of as landfill or incineration?

Globally, about 20% to 40% of fish market waste is disposed of through landfill or incineration. This is a common practice, especially in markets without the infrastructure to repurpose waste effectively.

While many markets are increasing their efforts to recycle and repurpose fish waste, landfill disposal remains a major environmental concern for the industry.

What waste reduction practices are in place, such as donations, improved storage, or better inventory management?

To reduce waste, many fish markets are adopting various waste reduction practices. These include donation schemes for unsold fish, improved cold storage systems, inventory management practices, and real-time sales adjustments.

Additionally, the industry is moving towards more sustainable practices, such as the circular economy approach, which encourages the repurposing of waste for other uses like fishmeal or bioenergy production.

How has the waste percentage changed over the past three to five years, and what trends are emerging in the industry?

Over the past 3-5 years, fish market waste has decreased due to improvements in cold-chain infrastructure, technological advancements in fish processing, and stricter sustainability regulations. These trends have led to better waste management and higher repurposing rates.

There is also a noticeable trend toward circular economy practices, with a larger portion of waste being redirected to secondary markets instead of being discarded in landfills.
