Types of sources you need to learn about the life cycle of the fish species and the conservation challenges:
For the fish species assignment, these 2 have popular press articles, as well as scientific/scholarly ones.
More scientific literature for fisheries:
Aquatic Science Collection
Journal articles, book chapters, reports, and conference proceedings published in the field of aquatic science, some in full text, 1965-present.
Broad coverage of "applied biology" including aquaculture and fisheries. Incluldes journal articles, book chapters, monographs, theses, patents, software, audiovisual materials, and technical reports. 1970-present.

Other useful databases, specific to general:
Zoological Record - Animal (including fish) research from 1864 forward.
BIOSIS Citation Index - Biology research from 1969 forward.
Biological and Agricultural Index - Research literature from 1984 forward.
Web of Science; Science Citation Abstracts - High impact research in all sciences from 1900 forward. Search by "cited reference."
Tips to find species info:
1. Search both common and scientific names. Scientific articles may use one, the other, or both.
Be aware that sometimes the scientific name changes over time!
Connect them with OR - for example:
Brook trout or Salvelinus fontinalis
Using OR makes the results set bigger.
2. To find habitat or life history info, link species name with those terms using AND:
(Brook trout or Salvelinus fontinalis) and
(habitat or life history)
Using AND makes the results set smaller.
The parentheses ( ) makes the logic work. If you don't understand how, please ask!
3. Use a wildcard, e.g. the asterisk (*), question mark (?) or dollar sign ($) to widen your search. Each platform has its own rules.
In EBSCO databases, searching the term fish* will find anything starting with F-I-S-H
including fish, fished, fishing, fisher, fisheries, etc.
Some platforms, including Google/Google Scholar, do this automatically (without a symbol).
4. Use the database tools to narrow a search with many hits - narrow by date, or type of publication (source type), language, or geographic area.
