Hypothesis
Individual variation in risk-prone feeding behavior and activity may explain differences in feed intake and growth of cultured sole.
Conclusion
Feeding consistency, swimming activity, and boldness are related to feed intake and growth of sole in captivity.
Supporting Evidence
- Fish with higher variation in feed intake had lower total feed intake and growth.
- Active fish showed significantly higher feed intake and growth.
- Bolder fish had higher feed intake and growth rates.
Takeaway
Some sole fish eat more and grow better than others because of their behavior, like how bold they are and how much they swim.
Methodology
The study involved two growth periods where fish were housed communally and then individually to measure feed intake, growth, and behavior.
Potential Biases
Potential bias due to the selection of fish based on growth rates.
Limitations
The study was conducted in a controlled environment, which may not fully represent natural conditions.
Participant Demographics
Juvenile sole (Solea solea) with an initial weight of 59.5±6.5 g.
