    Los cladóceros son una fuente clave de alimento vivo para larvas de peces y crustáceos, pero el potencial nutricional de muchas especies sigue siendo desconocido. Scapholeberis mucronata es un cladócero poco estudiado en Colombia sin antecedentes sobre su potencial reproductivo. Este estudio evaluó sus aspectos reproductivos, crecimiento poblacional y características morfométricas en condiciones de laboratorio, utilizando tres dietas microalgales (Scenedesmus dimorphus, Chlorella minutissima y su mezcla 1:1) en concentraciones de 2×10⁵, 3×10⁵ y 4×10⁵ cel.mL⁻¹. Los mejores resultados se obtuvieron con la dieta mixta, registrando la mayor fecundidad (37 neonatos), densidad máxima (10,133 ± 305.51 y 10,466.67 ± 305.51 org.L⁻¹), tasa de crecimiento (0.18 ± 0.01), tiempo de duplicación (3.94 ± 0.17 y 3.76 ± 0.15 días) y rendimiento (1,283.33 ± 76.38 y 1,366.67 ± 76.38). En neonatos, la mayor longitud total (260.0 ± 6.3 µm) y ancho corporal (133.8 ± 4.2 µm) se encontraron en la dieta S. dimorphus, mientras que, en adultos, la LT osciló entre 476.3 ± 12.2 µm y 467.7 ± 13.4 µm y el AC entre 304.8 ± 14.3 µm y 294.9 ± 10.7 µm. En conclusión, S. mucronata alimentado con la dieta mixta alcanza altas densidades en poco tiempo, lo que sugiere su potencial para la producción masiva como presa viva en la alimentación de larvas de peces dulceacuícolas de interés comercial.

    Enriquecimiento ambiental en ocelotes (Leopardus pardalis linnaeus, 1758) mantenidos en cautiverio en el CAV de CVS de Montería Córdoba
    (CAV Centro de atención y valorización de Fauna silvestre y C.V.S (Montería- Córdoba), 2023-02-17) Torres Díaz, Elvis Francisco; Yepes Escobar, Juan; Muños Rojas, Alberto Elías
    At the Center for Attention and Valuation of Wild Fauna (CAV) of the Regional Corporation of the Sinú and San Jorge Valleys, wildlife specimens are received by means of seizure, rescue or voluntary surrender, they are medically and biologically valued, providing all the necessary care according to the conditions of the specimen. Within the framework of these protocols is the morphometry process, where body measurements of the animal are taken. On the other hand, the veterinary medical assessment is in charge of evaluating the state of the individual, to later determine if they will go to quarantine or if they can be released immediately. If quarantine is carried out, adequate biological environment, nutritional diet and monitoring are carried out, according to age, size, sex and species. When the animals fail to survive captivity, diseases or accidents, a necropsy is carried out, in order to obtain an accurate verdict of death, organ conditions, sampling, etc. In the rehabilitation stage, one of the problems that is observed in animals that are in captivity is the loss and gradual deterioration of the behaviors that they need to survive in their natural habitats. In carnivorous species such as cats, the behaviors that are most affected are those that are related to illegal trafficking hunting activities. The objective of this internship work was focused on carrying out different types of environmental, behavioral, nutritional and olfactory enrichment in order to help rehabilitate a female leopard pardalis species in order to help her improve her stress and hair loss to thus being able to give it an adequate rehabilitation and proceed to release it in its natural habitat. For this work, different types of enrichment were carried out for this species, and through blood counts and nocturnal cameras it was possible to analyze various behaviors which helped this species of ocelot in the CAV of the CVS for its subsequent rehabilitation.
