Discussion
- Chemical pars are assumed to relate to ash-free dry mass; MaleFaga1993 report ash free dry mass over dry mass ratio of 0.263 - 0.297 with mean 0.279, which makes del_W = 3.5842
- mod_1: tL data added to determine growth; the low respiration and excretion is incompatible with the high growth; predicted fluxes have been divided by 1e3 to match observations
Facts
- After hatching _B. mikado_ passes through a cydippid larva stage with a pair of tentacles (Ref: KasuIshi2000a)
- B. mikado loses its tentacles at a total length (TL) of ca. 15 mm, becoming similar to the adult morphology (Ref: KasuIshi2000b)
- In Japanese coastal waters, B. mikado is the predominant ctenophore species and is most abundant from late summer to mid-fall in Tokyo Bay (Ref: KasuIshi2008)
- The Total length (TL) of larval B. mikado is considered the length from the aboral pole to the mouth; For larvae with developing oral lobes and for the post-larvae, TL is the length from the aboral pole to the end of the lobes (Ref: KasuIshi2002)
- The ammonia and phosphate excreted by B. mikado population might represent around 21% of the standing stock of nutrient in the seawater of Tokyo Bay (Ref: KasuIshi2000a)
- Hermaphrodite (Ref: Wiki)
