CRIMAC Workshop on applying in-trawl and towed camera systems to scientific surveys

Objectives

In-trawl and other towed camera systems are becoming increasingly available and offer less invasive sampling with higher spatial and temporal resolution. Combined with machine learning algorithms for automated image analyses and near real time data processing and transfer, the systems offer great potential as sampling tools in scientific surveys. However, only a few surveys have so far implemented trawl-camera based sampling as a routine praxis. 

The aim of the workshop is to share knowledge on the latest developments and initiatives within the application of cameras to scientific trawl surveys. Topics that will be covered include 1) image data collection, processing and transfer methods, 2) collection of representative physical biological samples (e.g. open/close codend systems) and 3) how to include the data in assessment models. Participants will be invited to contribute to a manuscript that aims to provide recommendations for non-invasive scientific sampling with towed and in-trawl cameras based on the workshop outcomes. 

Approach

The workshop is organized in three parts, and we invite presentations to parts 1 and 2:

1. Stock assessment surveys: What information is currently required from trawl samples and how can it be replaced by image data?
2. Examples of planned or implemented use of in-trawl and towed camera systems in scientific surveys: Technological solutions, including methods for collecting biological samples, and sampling design
3. Discussion and summary recommendations
