Morphology
This is a straightforward adjective+noun composition: 'blue' (color) modifying 'jack' (a type of fish), so a B1 learner who knows both words can infer it denotes a jackfish that is blue. The specific taxonomic detail (a small salmon found in particular regions) is specialized knowledge, but the core meaning—a blue-colored fish called a jack—is transparently derived from the constituents.
Etymology
Blue jack likely comes from two simple words: blue for the fish's colour and jack a name fishermen used for young or small salmon. So the picture of a small blueish salmon explains why the name means 'a small salmon' today.
