In a large, open system like Lake Michigan this represents a significant increase in available habitat and it is important to understand how this increase may impact our ability to sample larval yellow perch in an unbiased manner. We measured the vertical distribution of larval yellow perch in southern Lake Michigan as a function of size, age, and diel period. Larval yellow perch were collected from two zones (surface and epilimnion) from 1 to 32 km from shore in 2001 during the day; on four dates surface samples were also collected at night. Results indicate larval perch are more abundant at the surface at night than during the day. Larval yellow perch < 15 mm total length (TL) and younger than 18 days post hatch were found in both surface and epilimnion habitat during the day, but larvae > 15 mm TL were captured only in the epilimnion and farther than 5 km from shore, which suggests a different spatial distribution for larger, older larvae. Diel differences in larval abundance and size at the surface suggest more and larger larvae will be caught for a similar effort at night as compared to daytime sampling. Observed differences in larval distribution with size and age also suggest that sampling concentrated nearshore and/or at the surface has the potential to under-sample larger/older yellow perch larvae in Lake Michigan.}, number={3}, journal={JOURNAL OF GREAT LAKES RESEARCH}, author={Fulford, Richard S. and Rice, James A. and Binkowski, Fred P.}, year={2006}, pages={434–441} } @article{dettmers_janssen_pientka_fulford_jude_2005, title={Evidence across multiple scales for offshore transport of yellow perch (Perca flavescens) larvae in Lake Michigan}, volume={62}, ISSN={["0706-652X"]}, DOI={10.1139/F05-173}, abstractNote={ Most freshwater fishes have short pelagic early life stages. Lake Michigan presents an interesting scenario for yellow perch (Perca flavescens), a species with a long pelagic larval stage that may not be well adapted to lakes with an expansive pelagic environment and extensive offshore transport. We investigated the possibility that early life stages of yellow perch were transported well offshore from their nearshore spawning grounds and explored whether food resources were more or less favorable offshore. To determine the extent to which pelagic age-0 yellow perch moved offshore, we sampled at multiple scales ranging from local (<2 km) to across the lake (>120 km). Evidence of offshore movement by fish larvae occurred at each scale. Yellow perch larvae were quickly transported offshore from nearshore spawning sites and remained in the offshore pelagia to sizes of at least 30 mm. Zooplankton density was greater offshore than nearshore, suggesting that pelagic age-0 yellow perch find improved food resources offshore compared with their nearshore spawning sites. Currents operating at oceanographic scales likely influenced the offshore movement of pelagic age-0 yellow perch in Lake Michigan. These currents, coupled with prey availability for pelagic age-0 individuals, may influence the recruitment success of this species. }, number={12}, journal={CANADIAN JOURNAL OF FISHERIES AND AQUATIC SCIENCES}, author={Dettmers, JM and Janssen, J and Pientka, B and Fulford, RS and Jude, DJ}, year={2005}, month={Dec}, pages={2683–2693} } @article{fulford_2003, title={Bridging the communications gap: Hearing-impaired professionals in fisheries science}, volume={28}, number={4}, journal={Fisheries}, author={Fulford, R.

The system design is based on batch culture methodology, which is easily customized to the feeding requirements of a larval system and optimizes the nutritional value of brine shrimp. This system can be set up quickly and provides stable temperature and aeration under a variety of external conditions. Harvest and separation of nauplii is facilitated by the shape of the culture vessel and placement of a light near the bottom of the vessel. During 14-d feeding trials, mean percent hatch of brine shrimp nauplii was 71% (59–81%) at 24 h and 83% (74–94%) at 28 h. Hatching rate was consistent across a range of initial cyst densities.}, number={3}, journal={PROGRESSIVE FISH-CULTURIST}, author={Fulford, RS and Rutherford, DA}, year={1998}, month={Jul}, pages={236–238} }
