Anadromous Fish Restoration Update
Location: Middle and Upper Bay
The anadromous crew sampled the Patuxent and Choptank Rivers last week for hickory and American shad. Sampling on the Pax occurred about a mile above the route 4 bridge, and catches for hickory shad were very low. Gizzard shad dominated the sampling area; more than I have ever seen, not a good sign! On the Choptank River sampling took place above the Greensboro boat ramp, and we encountered moderate numbers of hickory shad that were intertwined within large schools of white perch. A couple of large stripers have been observed on both rivers. It is still a bit early for the American shad run, but one was caught on the Pax. Temps have been running between 16°C and 20°C on both tribs.
Brood collection for hickory shad started off poorly last week (4/7) as we laid a big goose egg the first day. Conowingo Dam limited flows forcing the hickory shad to back off on there spawning run until flows increased. Collections improved the second day (4/8) with approx. 80 fish caught and transported to the Manning hatchery to induce spawning. Alewife herring and large stripers are also utilizing the waters around Lapidum boat ramp.
