NEKTOFORM

NEKTOFORM is a private web-based platform for extracting, reviewing, and using acoustic features from large-scale echosounder datasets. It is designed for real survey and operational data, including noise, variable data quality, and complex biological structure. The platform supports expert processing of fish schools, krill swarms, and scattering layers, then turns those outputs into analysis-ready datasets for fisheries workflows, ecological analysis, environmental monitoring, and model-based decision support. Where required, Cupar Analytics also develops custom proprietary models that combine acoustic outputs with environmental, operational, and fishery-specific data to support forecasting, planning, and decision-making. For fisheries clients, NEKTOFORM helps move from acoustic observations to practical decisions about where to fish, when to go, which conditions to target, which schools or swarms to prioritise, and how to use vessel time more efficiently.

NEKTOFORM processes echosounder data through a structured workflow that includes quality filtering, feature detection, interactive review, and feature-level summarisation. It identifies spatially connected acoustic features such as fish schools, krill swarms, and scattering layers, while supporting expert adjustment of processing settings, inspection of results, and refinement of outputs. The platform is designed around two complementary modes:

• Expert processing mode provides the full acoustic workflow for filtering, feature extraction, review, and dataset preparation.
• Client view mode provides a simplified interface for viewing expert-processed schools, krill swarms, tracks, maps, and feature summaries without exposing the full processing complexity.

A decision-support layer can then combine acoustic outputs with environmental data, proprietary models, and client-specific operational context to support forecasting, trip planning, target prioritisation, and fisheries decision-making. Decision-support tools are developed around each client’s data, fishery, and operational questions. This can include custom models for forecasting fish or krill swarm distribution, identifying favourable fishing conditions, prioritising acoustic targets, estimating relative fishing opportunity, or supporting trip-planning decisions.

Fisheries workflows

• Extract fish schools, swarms, scattering layers, biomass indicators, NASC summaries, and survey-scale acoustic metrics.
• Store and analyse private processed datasets for ongoing monitoring and comparison across surveys.
• Identify spatial and temporal patterns in fish or krill distribution.
• Support decisions about where to fish, when to go, what conditions to target, and which schools or swarms to prioritise.
• Prepare inputs for downstream modelling, stock assessment, forecasting, and operational decision support.
• Combine acoustic outputs with environmental data, vessel data, and catch data.
• Develop proprietary forecasting and decision-support models using acoustic, environmental, vessel, catch, and operational data.

Ecological and environmental applications

• Analyse krill, fish, and pelagic ecosystem structure.
• Quantify spatial and temporal patterns across surveys, regions, and monitoring periods.
• Link acoustic features to predator observations, tracking data, or ecological covariates.
• Integrate acoustic outputs with environmental datasets such as temperature, oxygen, light, currents, bathymetry, or sea ice.
• Support conservation monitoring, offshore wind environmental assessment, impact studies, and long-term ecosystem monitoring.

NEKTOFORM is a private client platform. Access is designed for organisations working with their own acoustic datasets, processed products, and proprietary models. Depending on the client workflow, NEKTOFORM can support expert processing, simplified viewing of reviewed outputs, private dataset storage, and integration with modelling or decision-support tools.
