Revolutionizing Aquaculture: Ensuring Continuous Delivery and Premium Quality

In today’s competitive aquaculture industry, consistent and reliable delivery is the key to success. To secure a permanent spot on menus and in markets, aquaculture operations must guarantee a steady flow of premium-quality fish. The system enables accurate forecasting by implementing structured strategies. It also designs tank clusters for weekly harvests to ensure dependable deliveries and scalability.

With a productivity rate exceeding 1 ton fish per cubic meter of water per year, this approach is highly efficient. It achieves efficiencies that are 100 times greater than traditional open pond systems. Such innovation not only enhances sustainability but also sets a new benchmark in high-yield aquaculture.

The document is structured to outline:

  1. Core Operational Strategies: Detailed insights into Double Split and Double Cull methods for achieving high productivity and maintaining system balance.
  2. Ensuring Reliable Deliveries: A robust reliability margin and contingency measures to guarantee uninterrupted operations, even during disruptions.

Gone are the days of relying on the unpredictable “catch of the day.” This document introduces a cutting-edge aquaculture approach. It centres

around these strategies and forms a sustainable, high-yield solution. This meets market demands with precision and reliability.


Core Operational Strategies

Double Split (16 Tanks)
  • By grading the batch, we can first harvest the largest fish. This ensures all 4 harvests are equal in size. It promotes uniformity and optimizes resource use.
  • Each batch or cycle begins in a single tank. The stock undergoes two splits, resulting in a total of 4 tanks per cycle.
  • Provides 4 harvests per batch, occurring one per week.
  • With a 4-month growout period, the system accommodates 3 cycles per year, ensuring a steady and predictable harvest schedule.
Double Cull (2 Tanks)
  • Operates on a continuous rotation where half the stock is culled during each cycle.
  • Produces 3 harvests per batch: one small, one medium, and one large (regular).

Production Summary

This summary highlights the alignment of projected yields with market demands. It also shows how they match operational goals. This supports the vision of continuous and scalable production.

Notes:

  1. The yield per harvest in Double Split batches is 6 tons. This yield is calculated based on optimized growth. It also considers resource use across the 16 tanks allocated to Double Split operations.
  2. The yields in Double Cull batches are distributed as follows.
    • There are 3 tons for small fish (S).
    • There are 3 tons for medium fish (M).
    • There are 6 tons for large fish (L).
    • This distribution reflects the growth stages achieved within the cycle.

Utilization Plan Summary

This utilization plan maintains reserve capacity and ensures operational flexibility. It minimizes risks linked with disruptions. Additionally, it aligns resources with the growth stages of the fish.

Tanks are not fully utilized before the first split. Therefore, tanks 2 to 4 in the Double Split process operate at reduced capacity. Based on growth curves and the timing of splits, the following utilization percentages are estimated:

Tank GroupNumber of TanksUtilization PercentageNotes
Double Split4100%High-intensity operation with 4 harvests per cycle (16 tanks per batch).
Double Cull2100%Produces 3 harvests per batch: small, medium, and large. Adjusts to failures by replacing stock from these tanks. Grading ensures equal harvests and selects GI candidates.
Moderate Utilization436%Receivers of the first split from Double Split tanks.
Low Utilization817%Receivers of the last split, used for extended growth or reserve capacity.
Total Utilization18∼50%Balances operational intensity with flexibility.
Role of Reserve Capacity

Tanks operating at 36% and 17% utilization serve as reserve capacity. They provide additional flexibility during disruptions. Double Cull tanks are the primary replacement.


Reliability Margin: Ensuring Consistent Operations

This section explains the rationale behind the current preference for three clusters in one location. It weighs cost-effectiveness, logistical simplicity, and scalability against the ideal setup of three clusters across two locations.

Definition
  • The reliability margin provides a buffer to ensure operations continue even during tank failures or disruptions.
  • A 50% reliability margin ensures the core operations. These operations, Double Split and Double Cull, can proceed uninterrupted. This remains true even if up to 50% of the tanks are affected.
  • Three clusters in two separate locations is the preferred solution for guaranteeing deliveries even in the event of significant disruptions. Nevertheless, the current plan utilizes three clusters in one location, balancing operational efficiency and scalability.
  • Extra Tank for Enhanced Reliability. A 19th tank can serve as a “cool tank.” It is where fish are prepared and rested before harvesting. This reduces stress and ensures optimal quality. It acts as an additional buffer, supporting stock from failed tanks when disruptions exceed the 50% reliability margin. The tank offers operational flexibility. It handles peak demand periods or temporary overcapacity. This ensures smooth growth cycles and harvest schedules.
Use cases: Stock Replacement in Case of Tank Failure

If a tank fails, the fish stock in that tank is lost. We replace it using stock from a Double Cull tank. Here’s how it works:

  1. Initial Tank Stock: Each tank begins with 16,000 fish.
    • If a tank fails at this stage, they replace the lost stock. They use 16,000 fish taken from a Double Cull tank.
  2. After First Split: Each tank contains 8,000 fish.
    • If a tank fails at this stage, 8,000 fish are taken from a Double Cull tank. They replace the lost stock.
  3. After Last Split: Each tank contains 4,000 fish.
    • If a tank fails at this stage, we replace the lost stock by taking 4,000 fish. These fish are taken from a Double Cull tank.

In all cases, the lost stock is replenished directly from Double Cull tanks. This ensures the same number of fish are available across the system. This process prevents delays or reductions in harvest schedules for the large sized fish.


Summary

Moreover, the design aligns with global sustainability goals by significantly reducing water consumption and maximizing output per unit area.

This system achieves more than 1 ton per cubic meter of water. This efficiency is 100 times greater than traditional open pond systems. Such optimization highlights the sustainability and scalability of the aquaculture model, ensuring premium output with minimal resource use.

Each cluster will be designed to fit in a 20×50 greenhouse. This means roughly half of a football field is required for 1,000 tons of production.

**Conclusion **

The integration of structured strategies such as Double Split and Double Cull is crucial. A robust reliability margin directly supports these strategies. This combination reinforces the concept of continuous delivery, which is essential for consistent market presence. Each cluster operates 3 four-month cycles per year. It delivers 18 full harvests per cycle. This schedule translates to more than one harvest per week. This ensures weekly deliveries of premium fish, providing accurate forecasting and removing dependency on unpredictable “catch of the day” systems.

Adding a 19th tank as a cool tank optimizes harvest readiness. This ensures the highest quality fish are delivered. It meets last-mile requirements. This comprehensive system offers flexibility and scalability. It maintains a continuous supply chain. This makes it a sustainable and reliable solution for premium fish production.
