Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

External fertilization with internal insemination (Ref. 101419). This is also called 'internal gametic association' which describes another unique phenomenon of the reproductive process. In this phenomenon, the presence of the spermatozoa in the ovarian cavity is done through copulation, but the spermatozoa entry into the egg and subsequent fertilization only occurred externally when the eggs are spawned and came into contact with seawater (Ref. 101419).

Estimates based on models

Preferred temperature (Ref. 123201): 3.6 - 17.3, mean 12.9 °C (based on 37 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.4 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).

Alcichthys elongatus (Steindachner, 1881)
