Progress 04/01/13 to 03/31/18
Outputs Target Audience:I worked with undergraduate students at Penn State providing classroom instruction and laboratory instruction. I provided independent study opportunities for students in the Wildlife and Fisheries Science major and minor related to the goals of this project. I have worked with National Park Service personnel to develop a strategic plan for fisheries management in the Delaware River park units, colleagues in PSU Engineering to initate a project regarding fish passage, and personnel in the PA Fish and Boat Commission.

What opportunities for training and professional development has the project provided?In addition to our work with the National Park Service, several undergraduate students at Penn State have engaged in independent studies to evaluate the effectiveness of using benthic macroinvertebate and fish communities to assess the health or status of local streams. These studies have been designed to be hands-on, experiential learning exercises that have enabled students to review relevant literature and apply the methods on local streams as a way to learn how to frame questions related to the quality of habitat available and the fish and benthic macroinvertebrate communities that these habitats support. How have the results been disseminated to communities of interest?Results have been communicated via peer-reviewed publications, scientific presentations, informal reports, webniars, and direct communication with students. What do you plan to do during the next reporting period to accomplish the goals?

Impacts What was accomplished under these goals?
Work on Objective 1 was dependent on extramural funding that did not materialize during the time frame of this project. Thus, no work was completed on this objective. During this project, we worked as part of a team to develop Natural Resource Condition Assessments (NRCA) for units of the National Park Service. This effort allowed us to investigate the effectiveness of using indices based on the fish and benthic macroinvertebrate communities to evaluate the status of streams and water quality (Objective 2 of this project). Fort Necessity National Battlefield is primarily a cultural park, but it includes a variety of natural resources. We used existing information on the fish and benthic macroinvertebrate communities and an IBI approach to evaluate resource condition. Based on the macroinvertebrate indices and IBI, we found the aquatic species to warrant moderate concern. However, we found that the IBI may not reflect the quality of aquatic habitats present effectively. Based on the fish species present, we found the fish community to be in good condition. Efforts to complete an NRCA for Friendship Hill continue. During this project, one PhD student completed his study on the influence of pH and species interactions on the distribution of Brook Trout and Brown Trout in Pennsylvania streams. This study directly addresses Objective 3 of this project and was comprised of three parts. The first part examined shifts in Brook Trout and Brown Trout pH preference/avoidance after exposure to different pH conditions. Hatchery-reared Brook Trout and Brown Trout were exposed to different holding pH treatments in the lab for seven days prior to determining their behavioral response to pH. Preference was determined in a long trough where a gradient of pH (4.0-7.0) was presented to fish. Steep gradient choice tanks were used to determine avoidance. Hatchery-reared Brook Trout and Brown Trout pH preference or avoidance did not change due to changing holding pH suggesting that individuals of these species can be held in the laboratory at a pH different from the source waterbody for a short period of time without altering preference or avoidance behavior. The second part investigated the pH preference and avoidance of wild, adult Brook Trout and Brown Trout using the same methodology applied in the first study. The behavioral response of Brook Trout and Brown Trout to low pH is one of factor that may lead to the observed segregation pattern of the two species in Pennsylvania streams. Wild, adult Brown Trout showed a preference for pH 4.0 while wild, adult Brook Trout did not prefer any pH within the range tested (pH 4.0 - 7.0). Adult Brown Trout displayed a lack of avoidance at pH below 5.0, which is like that reported for juvenile Brown Trout. The avoidance pH of wild, adult Brook Trout (between pH 5.5 and 6.0) and Brown Trout (between pH 6.5 and 7.0) did not differ appreciably from earlier study results for the avoidance pH of juvenile Brook Trout and Brown Trout. The preference and avoidance pH results from this study were used to design the third portion of this study, the field experiments involving species interactions and pH. The behavior of wild, adult Brook Trout and Brown Trout (alone and in combination) was observed in study reaches that were manipulated to vary the level of acidity and CO2. In the artificial stream channel, most of indwelling fish (fish that spent some time on the treatment side during the control observation period) responded to acidification by moving to more neutral conditions (62% of Brook Trout and 68% of Brown Trout). Indwelling Brook Trout spent less time in acidic conditions during the acid treatment (41 ± 5%) than during the control period (94 ± 2%). However, elevated levels of CO2 may have caused their avoidance at a higher pH. Indwelling Brown Trout spent less time in the acid conditions during the acid treatment (44 ± 4%) than during a control period (98 ± 1%). The proportion of time spent in the acid water by indwelling trout decreased as negative interactions with other fish (such as chasing) increased. Presence of the opposite species did not influence the proportion of time spent in the acidic conditions. The results of this study do not support the hypothesis that acidification mediates the segregation of Brook Trout and Brown Trout in Pennsylvania streams. Confounding factors, relating to changes in CO2 associated with the acid manipulation, and issues relating to stocking density need further investigation to identify what role these may have played.

What opportunities for training and professional development has the project provided? One graduate student continues to work on his Ph.D. based on the evaluation of pH on trout distributions. How have the results been disseminated to communities of interest? Results from out work on resource assessment in National Parks have been disseminated through final reports to the agency. What do you plan to do during the next reporting period to accomplish the goals? We will sample fish and benthic macroinvertebrates at the sample sites selected in PA State Parks during 2015. Undergraduate students will be included in both the sampling and the data analysis to provide additional training opportunities. Publication of results from our pH studies are expected in 2015.
Impacts What was accomplished under these goals?
A study to evaluate water quality based on fish and macroinvertebrate communities was initiated in three Pennsylvania State Parks. Identification of sample sites was completed. Our work with the National Park Service to develop resource assessments for several parks was completed, and efforts were initiated at two additional park units. Data analysis and preparation of publications based on our experiments to evaluate the effect of pH on Brook Trout and Brown trout distribution in streams continues.
