Effects of Salinity on Fertilization, Hatching, and Larval Performance of Longfin Smelt Spirinchus thaleichthys

Table 1

Summary of larvae produced from wild caught longfin smelt Spirinchus thaleichthys at the FCCL from 2018 to 2021.

Year	Number of crosses	Fertilization (%)	Hatching (%)	Larval (0–40 dph) survival (%)
2018–2019	45	63.8 (n = 45)	94.3 (n = 15)	23.9 (n = 10)
2019–2020	29	42.8 (n = 29)	89.5 (n = 20)	68.4 (n = 16)
2020–2021	14	37.5 (n = 14)	91.7 (n = 7)	16.2 (n = 5)

Abbreviations: dph, days post-hatch; FCCL, Fish Conservation and Culture Laboratory Note. number of samples varied because fertilized eggs were used for other purposes.
