Short-term Cold Storage of Sperm from Six Neotropical Characiformes Fishes

Sperm of the following Neotropical Characiformes fish species were tested for cold storage: Brycon lundii, Piaractus mesopotamicus, Leporinus elongatus, Leporinus friderici, Prochilodus lineatus and Prochilodus marggravii. Each sperm sample was split into two aliquots. The first was placed into a plastic bag with air or oxygen and the second, in a plastic tube with air. The samples were maintai...

Early larvae ontogeny of the Neotropical fishes: Prochilodus costatus and P. argenteus (Characiformes: Prochilodontidae).

Early development of fish larvae is a highly dynamic process and its study may provide important information about ontogenetic development, bioenergetic growth, behaviour, taxonomic characteristics for identification in natural environments, identification of spawning areas, and population monitoring. With the aim to provide knowledge about their growth and behaviour, to support larval rearing,...

The effect of cold on platelets. II. Platelet function after short-term storage at cold temperatures.

Citrated platelet-rich plasma (PAP) was kept at cold temperatures or room temperature. After 4 hr or more at these temperatures, the PRPs were warmed 1 hr at 37#{176}C. This prevents the spontaneous aggregation seen in chilled PRP that is stirred immediately after warming. Platelet aggregation in response to connective tissue (CT), epinephrine, and adenosine diphosphate (ADP) was considerably g...

Short-Term Storage of Diluted Fish Sperm in Air Versus Oxygen

Herein we demonstrated the effect of oxygen and air atmosphere on the success of short-term storage of sperm obtained from rainbow trout (Oncorhynchus mykiss), sterlet (Acipenser ruthenus) and common carp (Cyprinus carpio) diluted in immobilizing media (100 mM NaCl, 40 mM KCl, 3 mM CaCl2, 1.5 mM MgCl2, 50mM Tris, pH 8.2 for salmonid fish, 17 mM NaCl, 1.7 mM KCl, 6 mM NaHCO3, 0.5 mM CaCl2, 0.5 m...
