Table 7.

Parameters used for estimation of the presence or absence of micropylar sperm attractant (MISA) in fish egg.

Species (Micropyle type) Staining (+) or no staining (–) of micropylar region by treatment Loss of staining ability of micropylar region by trypsin Efficiency of sperm entry in micropyle is affected (+) or not affected (–) by extracellular Ca2+ Presence (+) or absence (–) of MISA
CB FITC-WGA
Herring (I) + + Yes + +
Flounder (I) + + Yes + +
Trout (II) + + Yes + +
Anchovy (II)a + Yes + +
Goldfish (III) b NA
Loach (III) b NA
Zebrafish (III) b NA

aNote that anchovy micropyle is not stained by CB, but is stained by FITC-WGA.

bOther FITC-conjugated lectins tested (ConA, UEA, RCA, and LCA) did not stain micropylar region of eggs of these fish.

NA: not applicable
