2005offspringgenotypes

Data include ID and 12 microsatelitte loci genotypes of juveniles collected in 2005. IDs were marked as BDF-, BDM-, WDF-, and WDM-. DF and DM represent live and dead juveniles, respecitively, which were collected and reared in streamside hatcheries (B: Black Lake hatchery; W: Wolf Lake hatchery) for three months before being released to the river

2007offspringgenotypes

Data include ID and 12 microsatelitte loci genotypes of juveniles collected in 2007. IDs were marked as DF-, and DM- which represent live and dead juveniles, respecitively, which were collected and reared in a streamside hatchery (Black Lake hatchery) for three months before being released to the river

1625Adult genotypes by year01-10

Adult data captured in 10 years (2001-2010). Each year data include passive integrated transponder (PIT) tags, annual adult ID, sampling date, and genotypes based on 12 microsatelitte loci

2004offspringgenotypes

Data include ID and 12 microsatelitte loci genotypes of juveniles collected in 2004. IDs were marked as DF-, and DM- which represent live and dead juveniles, respecitively, which were collected and reared in a streamside hatchery for three months before being released to the river

2006offspringgenotypes

Data include ID and 12 microsatelitte loci genotypes of juveniles collected in 2006. IDs were marked as BDF-, BDM-, WDF-, WDM-, DF-, and DM-. DF and DM represent live and dead juveniles, respecitively. B and W represent streamside Black Lake and Wolf Lake hatcheries where juveniles were reared for three months before being released to the river. DF-, and DM- without B or D are live and dead juveniles that were collected during their drifting downstream at Upper Black Lake river

2003offspringgenotypes

Data include ID and 12 microsatelitte loci genotypes of juveniles collected in 2003. IDs were marked as BLJ-, DF-, and DM-. BLJs represent juveniles that were collected during their drifting downstream at Upper Black Lake river, DF- and DM- live and dead juveniles that were collected and reared in a streamside hatchery for three months before being released to the river

Reconnecting Fragmented Sturgeon Populations in North American Rivers

<p>The majority of large North American rivers are fragmented by dams that interrupt migrations of wide-ranging fishes like sturgeons. Reconnecting habitat is viewed as an important means of protecting sturgeon species in U.S. rivers because these species have lost between 5% and 60% of their historical ranges. Unfortunately, facilities designed to pass other fishes have rarely worked well for sturgeons. The most successful passage facilities were sized appropriately for sturgeons and accommodated bottom-oriented species. For upstream passage, facilities with large entrances, full-depth guidance systems, large lifts, or wide fishways without obstructions or tight turns worked well. However, facilitating upstream migration is only half the battle. Broader recovery for linked sturgeon populations requires safe “round-trip” passage involving multiple dams. The most successful downstream passage facilities included nature-like fishways, large canal bypasses, and bottom-draw sluice gates. We outline an adaptive approach to implementing passage that begins with temporary programs and structures and monitors success both at the scale of individual fish at individual dams and the scale of metapopulations in a river basin. The challenge will be to learn from past efforts and reconnect North American sturgeon populations in a way that promotes range expansion and facilitates population recovery.</p
