Discussion
- Author_mod_1: I found information on the number of eggs per female as a function of length in Anon2013 that was much higher than in Anon2015 but chose to not include it as the temperature was not provided
- Author_mod_1: I was surprised to observe that the weight coefficient for ab changed so much the parameter values
Facts
- Obligatory air breather (Ref: Wiki)
- Some 5,000 to 6,000 stacked electroplaques are capable of producing a shock at up to 600 volts and 1 ampere of current (600 watts) (Ref: Wiki)
- There is a male-biased sex ratio, (3:1) (Ref: redlist)
- Males are considerably larger than females (but fishtank wrongly says that males are much smaller than females) (Ref: redlist, fishtank)
- Eggs are deposited in a foam nest built by the male, using his saliva (Ref: Wiki)
- Males are much more abundant (Ref: AssuSchw1995)
- Stomage of 7 cm larvae only consists of eggs, that of 8 cm for 80% (Ref: AssuSchw1995)
- Young leave the nest at 8-16 cm (Ref: AssuSchw1995)
