Refuge Tracking in Weakly Electric Fish Across 54 Sensory Landscapes

This dataset contains raw behavioral tracking data from two species of weakly electric fish (Apteronotus albifrons and Eigenmannia virescens) performing a closed-loop refuge tracking task. The data captures the longitudinal position of the fish and the moving refuge across 54 unique sensory conditions, designed to modulate the signal-to-noise ratio (salience) of the environment.

Experimental Subjects

• Total Subjects: 10 Individuals.

• Species 1: Apteronotus albifrons.

  • N = 5 individuals.

  • ID Labels: Ankara, Antalya, İstanbul, İzmir, Mersin

• Species 2: Eigenmannia virescens.

  • N = 5 individuals.

  • ID Labels: Amasra, Ardahan, Erzincan, Gaziantep, Samsun

Each file is a standard Comma-Separated Values (.csv) file representing a single experimental trial.

Note on Time: Time stamps are not included in the columns to save space. Data was recorded at a fixed sampling rate. Sampling Rate: 25 Hz (frames per second).

Experimental Conditions (The 54 Conditions)

The dataset covers a full factorial design spanning 54 unique sensory landscapes (3×3×3×2=54).

Variables:

1. Illumination (3 Levels):

   • Light: ~300–500 lux (High visual salience)

   • Dim: ~20–50 lux

   • Dark: 0 lux (IR illumination only; No visual salience)

2. Conductivity (3 Levels):

   • Low: <50 μS/cm (High electrosensory salience)

   • Medium: ~300 μS/cm

   • High: ~700 μS/cm (Low electrosensory salience/Jamming)

3. Refuge Length (3 Levels):

   • 7 cm

   • 14 cm

   • 21 cm

4. Structure (2 Levels):

   • Windowed: Refuge contains longitudinal slots (visual/electric edges).

   • Non-windowed: Solid tube.
