Facts

  • wiki: The tarpon feeds almost exclusively on schooling fish and occasionally crabs.It is capable of filling its swim bladder with air, like a primitive lung. (ref: Wiki)
  • The first stage, the leptocephalus stage, or stage one, is completed after 2030 days.It takes place in clear, warm oceanic waters, usually within 1020 m of the surface.The leptocephalus shrinks as it develops into a larva; the most shrunken larva, stage two, develops by day 70.This is due to a negative growth phase followed by a sluggish growth phase.By day 70, the juvenile growth phase, stage three, begins and the fish begins to rapidly grow until it reaches sexual maturity. (ref: Wiki)
  • Stage-one larvae are usually found in clear, warm, oceanic waters, relatively close to the surface. (ref: Wiki)
  • Stage-two and -three larvae are found in salt marshes, tidal pools, creeks, and rivers.The habitats are characteristically warm, shallow, dark bodies of water with sandy mud bottoms. (ref: Wiki)
  • Tarpons commonly ascend rivers into freshwater. As they progress from the juvenile stage to adulthood, they move back to the open waters of the ocean, though many remain in freshwater habitats. (ref: Wiki)

Discussion

  • males are assumed to differ from females by {p_Am} only
  • All larval forms are given the same shape coefficient, del_M, due to lack of data
