Abstract:
The reproductive biology of the paddlefish (Polyodon spathula) was studied on specimens collected from Lake Cumberland, Kentucky, from September 1983 to July 1984. A total of 500 specimens was studied. Reproductive activity was observed on 17 April 1984 in the Big South Fork of Lake Cumberland. Seasonal differences were observed in sex ratios with more males than females occurring in the winter and spring. Movements were observed throughout the year, but these were accentuated prior to reproduction in the spring. Lake Cumberland paddlefish became sexually mature by Age Group V in males and VII

Abstract:
Age and growth parameters of paddlefish from Lake Cumberland were investigated from September 1983 through July 1984. Sex ratios observed were 60 percent male and 40 percent female. The average total length for all paddlefish was 135.3 cm with fish captured in net tackle having a smaller body size than those caught on snag lines. Fish from the Cumberland River exhibited a greater mean body length than those from other parts of the lake, and females were longer than males. The average body weight was 11.8 kg and showed similar trends as body length. Net-captured paddlefish weighed less than tho

Abstract:
Both Elasmobranchii and Acipenseriformes have a spiral intestine, developed by the intestine folding inward and twisting upon itself. A comparative analysis of the digestive system of examples of Subclass Elasmobranchii (sharks and rays) to Order Acipenseriformes (sturgeon and paddlefish) was conducted through gross dissection and scanning electron microscopy (SEM) analysis. Urobatis jamaicensis, Acipenser baerii, and Polyodon spathula were used due to accessibility. Gross dissection analysis yielded that the acipenserids have a columnar spiral valve with 8 infoldings, and U. jamaicensis has a

Polymer-coated controlled-release fertilizers (PCFs) are the most widely used class of fertilizers in the production of container-grown nursery plants. Nutrient release from PCFs is primarily influenced by temperature. The objective of this study was to determine the influences of temperature and time on the nutrient release patterns of three PCFs (each with a rated longevity of 8-9 months), each using a different coating technology: Osmocote Plus™ 15N-3.93P-9.96K, Polyon™ 18N-2.62P-9.96K, and Nutricote™ 18N-2.62P-6.64K.
