Light intensity plays a vital role. With increased light the fish’s vision improves, and they will become more wary of predators. The sun’s angle determines the amount of light entering the water. Low light angles penetrate the surface less because more of it is subject to refraction. That’s why it is easier to approach fish at dawn and dusk rather than at midday. Consequently, it is easier to approach fish during the seasons with lowered sunlight angles (winter, spring and fall).
Likewise, it is more difficult to approach fish during the summer season. The high sunlight angle illuminates the water and improves the fish’s vision. As a result, the more light that is present, the more observant the fish will become.
A bright sun over your back may conceal your position from the fish because the glare makes it difficult to detect your presence. You are hidden by the sun’s brightness. But if you cast a sudden shadow over the fish, you may alarm them because they fear that this shadow might be a bird swooping down upon them.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
