What opportunities for training and professional development has the project provided? All research projects involved mentoring ofgraduate and undergraduate students who greatly benefit from the opportunity of hands-on involvement in practical and applied agricultural research and development. How have the results been disseminated to communities of interest? As part of the objectives, researchers have worked closely with industry and students in the training and dissemination of results. Researchers collaborate closely with Kentucky Aquaculture Association and the Kentucky Department of Agriculture to ensure research based information is disseminated in a timely manner to constituents through workshops and training events. KSU researchers have an excellent relationship with the production industry and are often directly involved in on-farm validation and scale-up of operations. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
This research effort has resulted in improved aquaculture production technologies and practices in Kentucky and the region. Development of technologies which have allowed intensification of largemouth bass larviculture have decreased production costs and resulted in improved reliability of seedstock production. As part of this research, researchers worked closely with industry to develop commercial scale production of largemouth bass juveniles out of season which has decreased our reliance on out of state suppliers and improved overall production efficiency. The determination of copper sulfate tolerance of largemouth bass at different temperatures has greatly improved our growers ability to prevent disease outbreaks in largemouth during harvest and transport procedures. This is important because largemouth bass are particularly sensitive to many warm and cold water aquatic disease problems and nearly all production costs have been incurred at this time. Taurine determination has assisted in providing fish nutritionists with the necessary information to develop a species specific diet for largemouth bass. With this and data from previous research supported by NIFA, KSU researchers are now working with a local pet food manufacturer to produce species specific diets for largemouth bass in Kentucky, reducing feed costs to farmers by greater than 20%. We determined that high protein distillers dried grains (DDG)are well accepted and utilized by channel catfish. This is especially important as channel catfish is the largest segment of aquaculture in the US as well as in KY, and DDG from ethanol distillation is now widely available due to recent increases in ethanol production. There are also new technologies for ethanol manufacturing which produce higher protein co-products which has increased the production of DDG. Research on freshwater prawn larviculture and the evaluation of different genetic strains has resulted in improved production technologies for one of the most economically important crustacean species in the world. Producers in Kentucky and globally have benefitted from KSU's research efforts in maximizing production technologies for the freshwater prawn. This research has supported the continued expansion of aquaculture production in Kentucky and the US through improved production efficiency and technological development.

Progress 01/01/12 to 12/31/12
Outputs
OUTPUTS: Three studies were conducted during the reporting period. The first addressed Objective 3, to evaluate the effect of supplementing largemouth bass diets with the amino acid taurine. This builds off of a long series of bass nutrition research at KSU. In other strict predators adding taurine to the diet has improved survival, growth, and liver health. After 10 weeks there was no difference in weights of fish fed the four diets. Objective 4. Following up on evaluation of distillers dried grains (DDGS) in catfish diets we evaluated a new algae meal product. Just as fuel ethanol production has increased the supply 0f DDGS, the increased production of algae for biofuel is producing increasing amounts of algae meal. This study evaluated diets containing 10%, 20%, 40%, and 40% algae meal with added lysine. After 8 weeks, fish fed the diets containing algae meal were larger than fish fed control diets. Objective 5 was a follow up on prawn production. Freshwater prawns have a complex social structure which affects the growth of certain sexual morphotypes which impacts production and especially size variation. By growing all-males it may be possible to reduce this negative interaction. All-males were grown in three ponds and mixed-sex in three ponds. After 105 days total weight harvested did not differ between treatments. However, the percentage of harvested animals achieving market and premium weights (>30, >40g) was significantly higher in the all-male prawns. PARTICIPANTS: Dr. James Tidwell is the principal investigator on this project and Mr. Shawn Coyle is the co-investigator. The information generated from this research was recently presented at as the World Aquaculture Society annual meeting and will be published in appropriate Jourals for dissemination to the greater aquaculture community. TARGET AUDIENCES: The target audience for this research are existing aquaculture producers, persons interested in aquaculture, agriculture extension agents and aquaculture research personnel interested in the areas of nutrition, husbandry and chemistry. This is applied research with immediate application to on-farm use addressing basic research questions also important to the aquaculture community such as digestive enzyme function of larval fish and importance of organic carbon on heterotrophic bacteria. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
Objective 3: Based on this research it appears that the extra expense of taurine supplementation would not be justified in commercial diets. For Objective 4, these results were generated in cooperation with Eastern Kentucky University Center for Renewable Fuels Technology Center and Alltech Biotechnolgy Center. Alltech has already initiated a trial to follow up on these results and are working with KSU to evaluate commercialization of feed formulations. For Objective 6, economic viability of prawn production in the region should be improved based on these results.

Progress 01/01/11 to 12/31/11
Outputs
OUTPUTS: OUTPUTS: 2011/01 TO 2011/12 Two studies were conducted during the reporting period. The first addressed Objective 1, to evaluate commercially available Artemia replacement products and marine larval diets for first feeding of largemouth bass larvae. Traditionally largemouth bass fingerlings are initially reared in nursery ponds on natural zooplankton then transferred into tanks for feed training. This research builds off prior research in which largemouth bass larvae were successfully fed Artemia nauplii for two weeks followed by a gradual transition to salmonid starter feeds. This line of research has the potential to eliminate the unpredictable nursery pond phase improving inventory control and production planning. It could also allow for out-of-season controlled indoor spawning as timing is no longer associated with pond zooplankton availability. Objective 7: We evaluated sucrose application rates of either 0% (C:N=9.2), 25% (C:N= 12.4) or 40% (C:N=15.4) of the daily feed rate with feed application rates being reduced proportionally. Alkalinity was maintained at 100 mg/L by daily sodium bicarbonate additions in all treatments; with the 0% sucrose treatment serving as the inorganic carbon treatment. After 10 weeks, there were no significant differences in average weight or survival of tilapia between treatments. FCR and average dissolved oxygen concentrations were significantly lower in the 40% sucrose treatment; possibly indicating a benefit to the reduced feed rates and a disadvantage of the increased sucrose application. It appears that either organic or inorganic carbon can be used to satisfy the carbon requirement of heterotrophic bacteria in zero water-exchange biofloc systems. These findings have been disseminated through workshops and directly to end-users via on-farm instruction. PARTICIPANTS: Dr. James Tidwell is the principal investigator on this project and Mr. Shawn Coyle is the co-investigator. The information generated from this research was intitially disseminated through the annual meeting of the Kentucky Aquaculture Association, a producer organization. Subsequently, site visits and on-farm training were provided to interested farmers who have readily adopted and are utilizing these technologies. The results of both of these studies have been immediately implemented by private producers in Kentucky. Mayer's fish farm of Bardstown, KY has constructed an indoor system for intensive larviculture of largemouth bass and has been moderately successful in the first year. In 2011, Mayer's fish farm produced approximately 10,000 feed trained largemouth bass completely indoors, an estimated value of $5,000. Phillip McCoun of Shelbyville has converted a swine farrowing barn to indoor heterotrophic tilapia production using inorganic carbon supplementation. The first crop is doing well and he is currently expanding the operation.The results from these trials will also be presented at professional meetings such as the World Aquaculture Society annual meeting and will be published in appropriate Jourals for dissemination to the greater aquaculture community. TARGET AUDIENCES: The target audience for this research are existing aquaculture producers, persons interested in aquaculture, agriculture extension agents and aquaculture research personnel interested in the areas of nutrition, husbandry and chemistry. This is applied research with immediate application to on-farm use addressing basic research questions also important to the aquaculture community such as digestive enzyme function of larval fish and importance of organic carbon on heterotrophic bacteria. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
OUTCOMES / IMPACTS: 2011/01 TO 2011/12 Objective 1: ArtemacTM (Bio-Marine) and BioVita (Bio-Oregon) were compared with de-capsulated Artemia cyst as transitional diets after either one or two weeks of Artemia feeding. Fish fed live Artemia nauplii for two weeks and then transitioned to decapsulated Artemia for one week were significantly larger and had better survivals than fry fed other combinations. Based on this work it appears that it may be necessary to feed live feeds initially as the enzymatic digestive system of first feeding largemouth bass fry is likely not sufficiently developed to utilize prepared diets. This trial was conducted under semi-commercial conditions at a private producer farm to facilitate technology transfer. Over 10,000 feed trained fingerlings were produced, six weeks earlier than using conventional methods. The second study addressed Objective 7. It investigated tilapia growth, and water quality and microbial community structures in indoor biofloc systems supplemented with either inorganic or organic carbon sources. In recent years, zero water-exchange biofloc systems have been experimentally developed for marine shrimp and tilapia production utilizing well-mixed suspensions of particulate matter and associated microbial communities. Often referred to as heterotrophic biofloc systems, these microbial communities are usually dominated by heterotrophic bacteria requiring carbon supplementation for efficient nitrogen removal. One of the most significant challenges to stability and efficiency of production in superintensive bio-floc-based systems relates to management of carbon and nitrogen inputs. Customarily organic carbon in the form of simple sugars are added with the feed ration to achieve a C:N of >15. A major disadvantage to this approach is the increase in BOD associated with sugar application, and the large volume of waste-solids generated. The results of both of these studies have been immediately implemented by private producers in Kentucky. Mayer's fish farm of Bardstown, KY has constructed an indoor system for intensive larviculture of largemouth bass and has been moderately successful in the first year. In 2011, Mayer's fish farm produced approximately 10,000 feed trained largemouth bass completely indoors, an estimated value of $5,000. Phillip McCoun of Shelbyville has converted a swine farrowing barn to indoor heterotrophic tilapia production using inorganic carbon supplementation. The first crop is doing well and he is currently expanding the operation.

Progress 01/01/10 to 12/31/10
Outputs
OUTPUTS: Two studies were conducted during the reporting period. The first addressed Objective 4, to evaluate a new high protein form of distiller's grains. Channel catfish remains the nation's largest aquaculture industry but high feed prices have impacted profitability. Ethanol companies have recently developed modified processes to enhance ethanol yield and increase the crude protein content of distiller's grains (DDGS). The Control diet was similar to a commercial diet while experimental diets contained either 20%, 40%, or 40% DDGS with added lysine. After 9 weeks fish fed the 40% DDGS diet without lysine (57.0 g) were significantly smaller than the Control diet (77.7 g). Average harvest weights were significantly higher for fish fed 20% DDGS (86.8 g) than for fish fed either 40% DDGS (57.0 g) or 40% DDGS+Lys (73.7 g). There were no differences in FCR or survivals. These data indicate a 10% growth improvement by addition of 20% DDGS over the Control diet and that the 40% DDGS diet was likely limiting in lysine. The second study addressed Object 6, to compare production characteristics of hybrid crosses of freshwater prawns. Prawn production in the US is based on a small number of founder stock reused for over 20 generations. Two genetic strains of domestic prawns (Texas and Hawaii) and a wild strain (Myanmar) were crossed. Four test crosses were produced and compared with pure Texas strain. After 115 days prawns were harvested from ponds. Survival was significantly higher in the TxH cross than in the TxT, TxM or MxT groups. Specific growth rate (SGR) was significantly higher in the MxT than in the TxM or TxH crosses. In terms of premium sizes, the MxT cross had significantly greater percentage of animals >50 g and > 70 g than the HxT or TxH crosses. Morphotype data indicate that the Myanmar crosses likely had delayed sexual maturation in both sexes. The Myanmar crosses appear to possess positive production traits which might be exploited through further selection. Dissemination activities included presenting these data to several end user groups: Schneider, K., Coyle, S. D., Bright, L. A., Gomelsky, B. and Tidwell, J.H. 2010.
