Nursery habitat
where juveniles of a marine species occur
In marine environments, a nursery habitat is a subset of all habitats where juveniles of a species occur, having a greater level of productivity per unit area than other juvenile habitats. Mangroves, salt marshes and seagrass are typical nursery habitats for a range of marine species. Some species will use nonvegetated sites, such as the yellow-eyed mullet, blue sprat and flounder.
Overview
The nursery habitat hypothesis states that the contribution per unit area of a nursery habitat is greater than for other habitats used by juveniles for the species. Productivity may be measured by density, survival, growth and movement to adult habitat.
There are two general models for the location of juvenile habitats within the total range for a species which reflect life history strategies of the species. These are the Classic Concept: Juveniles and Adults in separate habitats. Juveniles migrate to adult habitat. General Concept: overlap of juvenile and adult habitats.
Some marine species do not have juvenile habitats, e.g.
Begin with the source’s own compact description: “Nursery habitat” is where juveniles of a marine species occur. The dossier treats that line as a proposition to test through Nursery, habitat and where, not as a finished interpretation.
Why this record matters
The phrase “where juveniles of a marine species occur” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q7070230. The Library of Congress control number is sh2015001190. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

Three-step research path
- Establish the record: confirm the title “Nursery habitat”, its source revision and the description used here.
- Expand the search: follow Nursery habitat primary sources, Nursery habitat archive and Nursery research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
