  Citation × Citation Citation Abstract Copy Title: Fish Hatchery Ways & Means Manual 1986 Abstract -- The idea for this manual was conceived in 1969, while I was serving as assist ant manager of a new facility on the southern Oregon coast. We had struggled with several problems that always occur at a new station, then later found a solution while visiting another hatchery. It occurred to me that if we had a communication system for ideas between hatcheries, problems could be solved quicker and better, and a more efficient operation could be achieved. In addition, I observed that many good ideas are developed, then later abandoned for whatever reasons. Often the idea was lost, although it might surface again years later. I felt this would be a way to record and document these ideas for anyone who might be able to use them: In 1983, I listed the project as an item on my yearly work plan and obtained approval to proceed with the project. A year was spent trying to develop a format for the manual, and two years was spent collecting information by visiting all hatcheries in the state. It is hoped that the material included ,will be of value in making fish culture easier, more efficient~ and a smoother ·operation. It is also hoped that this will only be a beginning. I envision that when someone has an idea they feel might be useful, that~they could send me a photo and a short explanation of the purpose. I could then, as needed, make copies and make them available to those who are interested. The manual is divided by five major areas of fish culture which are: adult handling, incubation, fingerling rearing, liberation, and miscellaneous. Each section is numbered by page, thus leaving the book open-ended and additional pages can be added to each section in the future. If there is more than one page number for a specific item (i.e. pond crowders), then the page number is the same, but a letter of the alphabet is also used (i.e. page 10, then page 10 A). As you will notice, each item that is included lists the hatchery it is at; therefore, if further information is needed, one can contact the hatchery that has the item.

This assessment combines the Brophy (2007) and Adamus (2005) approaches to quantify the extent and causes of habitat loss and hydrogeomorphic changes in tidal wetlands of four Oregon South Coast Estuaries. The potential for restoring critical habitat and wetland functions is ranked using Ecological Prioritization Criteria (Brophy, 2007), while indicators of function, risk, and integrity are evaluated using scoring models from the Adamus (2005) Hydrogeomorphic (HGM) Rapid Assessment Method. The extent of inundation (head of tide) during King Tide conditions was observed and documented by staff and volunteers. Field measurements of salinity concentrations and stratification during high and low flow were tabulated. The historic aerial photo record was examined to detect channel migration, floodplain re-vegetation, and human-caused alterations. Related studies were combined with these observations to provide a summary of estuary hydrology, sedimentation, and channel stability related to wetland establishment and loss in each of the four estuaries. Ecological priority scores (Brophy, 2007) varied with wetland size, tidal channel condition, connectivity, and diversity of vegetation classes. Wetlands were categorized as restoration or conservation types, and priority ranks for wetlands were depicted on orthophoto base maps. Tidal wetlands and nearby floodplain wetlands in a variety of geomorphic settings were surveyed using the HGM protocol, including one “reference” and one restoration site . The HGM survey scores 55 indicators, including botanical transects, used to rank wetland functions (calculated by indicator scoring models). Risks to wetlands include human disturbances in close proximity to the wetlands and floodplains, resulting from the narrow valley floors in this tectonically active region. Wetland integrity is threatened by a surprising large proportion of non-native species in the botanical transects, 40%. Wetland indicators that scored low, and could be restored or enhanced, are discussed in a restoration considerations narrative. Wetland descriptions include lists of plant species, grouped by wetland status, native/non-native, and perennial/annual persistence. In addition to the HGM scores, an analysis of cover and diversity of all plant species in plots, off-transect species diversity, and waterfowl food distribution was completed using a wetland vegetation database developed for the Oregon South Coast.
