mackerel
鯖 centers on the mackerel, a specific type of fish. The meaning is concrete and does not extend into abstract senses.
鯖 combines 魚 (fish) with 青, which likely contributes the sound. The character was created specifically for the mackerel.
The left side is a fish 魚, and the right side is blue 青. Picture a blue-backed mackerel: the fish with the blue color.
For セイ, imagine a mackerel saying its name: 'say' (セイ) — the fish says 'say' as it swims by.
