Biology     Glossary (e.g. epibenthic)

Adults are found in eel-grass beds near rocks. Feed on small invertebrates (Ref. 4742). Eggs are laid in the summer in a seaweed nest (Ref. 35388). Males grow faster than females (Ref. 4792). Oviparous, distinct pairing during breeding (Ref. 205). Used in salmon culture as cleaner fish (Helmut Tethmeyer, pers. comm.).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, distinct pairing during breeding (Ref. 205). Males build dish shaped nests and guard the eggs (Ref. 205). Also Ref. 103751.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00464 - 0.01241), b=3.08 (2.94 - 3.22), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.50 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.69-0.81; tmax=6).
Prior r = 1.54, 2 SD range = 1.18 - 2.00, log(r) = 0.43, SD log(r) = 0.13, Based on: 1 M, 2 K, 1 tmax, records
Vulnerability (Ref. 59153):  Low vulnerability (20 of 100) .
