Discussion
- mod_1: Wwi is assumed to include gonads
- mod_1: Refs for tp and tp_m included data on reproductive maturity (ready to spawn) and spawning periodicity (freq. of spawning). We subtracted the average of reproductive readiness by the shortest periodicity for males (1y) and females (2y) to get our estimates of puberty
- mod_2: ab, tp, Li, Wwb, Wwi, Ri data revised; tL_fi and tWw_fi data added
Facts
- length-weight: Ww in g = 0.00407*(TL in cm)^3.16 (Ref: fishbase)
- The pallid sturgeon is the largest freshwater fish in North America (Ref: Wiki)
