Largemouth bass (LMB; Micropterus salmoides) production for the food fish market is growing in the US. Traditionally, LMB producers in the US have relied on traditional earthen ponds as their primary production system for culturing this species. Largemouth bass producers using traditional earthen ponds are plagued by low survival, slow growth, poor food conversion ratio (FCR), losses to bird depredation, water quality problems, and disease issues. Largemouth bass producers believe these production-related obstacles, inherent to culture in traditional earthen ponds, have translated to reduced efficiency and profitability of farming operations and are inhibiting the growth of this aquaculture sector. The culture of LMB in a split-pond system (SPS) can ameliorate many of the inefficiencies documented by commercial LMB producers using traditional earthen pond systems. A SPS for LMB has the potential to solve the inherent limitations of low oxygen and waste treatment of traditional earthen ponds, as it confines LMB to a smaller area (fish basin, 15–20% of total pond area) in a pond. As a result, energy-efficient aeration and water circulation are improved over the entire culture area. The advantages of the SPS for LMB production can revolutionize the production of this expanding food fish species in the US. The objectives of this project were to evaluate the production performance, water quality, fish health metrics, and economic feasibility of raising stocker LMB (15–25 cm fingerlings) in SPS compared to traditional earthen ponds. The experiment was conducted at American Sport Fish in Montgomery, Alabama. A total of 8 ponds were used, including four traditional earthen ponds (0.4 ± 0.0 ha) and four SPS (0.24 ±0.11 ha). Fish weights and lengths were obtained at stocking and thereafter monthly until harvest. Commercial ponds were stocked with feed-trained LMB fingerlings (5–7 cm total length) sourced from American Sport Fish. Pond water samples were collected weekly from study ponds and transported to the E.W. Shell Fisheries Research Center, Auburn University, on ice for water quality analysis. Weekly water quality tests were conducted using a photometer (YSI 9300 Photometer) and included ammonia and nitrite testing, while monthly water quality tests included total alkalinity, total hardness, chloride, and nitrate. Weekly water parameters measured on-site at the farm included dissolved oxygen, temperature, salinity, pH, and Secchi disk depth. Ponds were sampled monthly throughout the 4-month trial to track the growth of LMB fingerlings. Approximately 30–50 fish were sampled from each pond to determine length and weight. During monthly sampling, a subset of fish was transported on ice to the diagnostic laboratory at the Alabama Fish Farming Center in Greensboro, Alabama for a fish health assessment. Commercial ponds were harvested in October 2023 when LMB reached stocker size (15–25 cm total length), and analysis of production parameters is underway. An enterprise budget will be developed from fixed and variable costs associated with this project to compare the cost of production of raising LMB fingerlings to stocker sizes using SPS and traditional earthen ponds.
