Core Responsibilities

Primary Functions

Conduct consistent, high-accuracy visual and manual sorting of incoming and on-line fish by species, size, weight, and quality grade to meet production specifications and customer requirements while maintaining required throughput rates.
Inspect fish for defects, contamination, parasites, bruising, and spoilage, removing substandard product from the line and documenting rejects to support quality traceability and yield analysis.
Operate and monitor conveyor belts, vibrating graders, automatic size graders, and hand grading stations, adjusting pace and sort parameters to optimize line flow and minimize bottlenecks.
Weigh and measure fish using calibrated scales and gauges, record weights and counts accurately for batch records, and ensure all packaged lots contain correct counts and weight tolerances.
Apply HACCP, GMP, and company-specific food safety procedures at all times: maintain temperature control, use appropriate PPE, and follow segregation protocols for allergens and bycatch species.
Package sorted fish into correct containers (boxes, trays, totes) and label them with lot numbers, weights, dates, and traceability information to ensure chain-of-custody and regulatory compliance.
Perform species identification and grading using provided guides and standards, escalating ambiguous or suspect specimens to quality control or supervisors for confirmation.
Collaborate with Quality Assurance to participate in routine and ad-hoc sampling, microbial swabbing, and visual audits to support compliance with internal quality standards and third-party certifications (e.g., MSC).
Maintain accurate production logs, shift handover reports, and reject documentation in electronic or paper formats to support inventory, billing, and quality investigations.
Remove and document bycatch or foreign material found on the line, following waste handling procedures and recording incidents to support sustainability and regulatory reporting.
Participate in start-up, line-change, and clean-in-place (CIP) activities, ensuring equipment is set to correct parameters and no cross-contamination occurs between product runs.
Follow cold room and blast-chill procedures to maintain product temperature targets from receiving through packaging and final storage, including verifying thermometer readings and reporting deviations promptly.
Support yield optimization efforts by flagging recurring defects, suggesting sorting parameter adjustments, and working with supervisors to reduce trim loss and rework.
Load and unload fish bins, totes, and skids using safe manual handling techniques and, where certified, operate pallet jacks or forklifts to move product between staging and processing areas.
Participate in continuous improvement initiatives and line efficiency (OEE) meetings by providing frontline feedback, proposing small process changes, and trialing new sorting heuristics or fixtures.
Adhere to all occupational safety rules, report hazards, and assist in incident/near-miss investigations, including using cut-resistant gloves and other PPE when handling knives or sharp fins.
Maintain cleanliness of sorting lines, workstations, and immediate work areas during shift, performing regular wipe-downs and disposals to meet sanitation schedules and reduce cross-contamination risk.
Cross-train on adjacent processing stations (trimming, filleting, packing) to provide flexible coverage during peak season or staffing shortages while preserving product and safety standards.
Communicate effectively with supervisors, QC personnel, and other production staff about line issues, equipment malfunctions, or quality trends to ensure rapid corrective actions.
Apply simple mechanical troubleshooting for common conveyor and grading equipment issues (belt alignment, jam clearances, sensor cleaning) and escalate more complex problems to maintenance while minimizing downtime.
Follow documentation and regulatory requirements for catch origin, species declarations, and quota reporting where required, ensuring accurate lot-level metadata for traceability.
Participate in seasonal ramp-ups, special projects, and customer-specific sorting or packing runs, adapting to varying product specifications and documentation needs.

Secondary Functions

Assist sanitation teams with scheduled deep-clean activities and rapid-response cleaning during shift transitions.
Support periodic inventories and stock counts for packaging materials, labels, and holding bins to prevent stockouts that impact line uptime.
Help maintain spare parts and tool organization at the line, reporting shortages of blades, belts, or PPE to supervisors.
Contribute to training and onboarding of new sorters by demonstrating sorting standards, safety practices, and documentation expectations.
Help coordinate logistics for moved product between processing, freezing, and shipping areas to maintain FIFO and temperature integrity.
Participate in internal and external quality audits, providing records and answering procedural questions about sorting and grading operations.
Provide feedback on ergonomics and workstation improvements to reduce repetitive strain and improve long-term productivity.
Support waste-reduction programs by separating recyclable and compostable materials and suggesting process changes to reduce discard rates.
Take part in toolbox talks and daily safety briefings, raising concerns and suggestions to improve workplace safety and productivity.
