Eficácia da ivermectina oral no controle de Psoroptes ovis e Leporacarus gibbus em coelhos naturalmente infestados

O objetivo do trabalho foi avaliar a eficácia da ivermectina administrada por via oral no controle de Psoroptes ovis e Leporacarus gibbus em coelhos naturalmente infestados. Foram selecionados 20 coelhos adultos, distribuídos na mesma proporção de ambos os sexos, em dois grupos experimentais, compondo dez animais por grupo. No grupo controle foi administrado o mesmo volume do tratamento de solução salina, enquanto o grupo tratado recebeu dose única de ivermectina oral (400 µg/Kg). O diagnóstico dos ácaros foi realizado com auxílio de microscópio estereoscópico após a devida coleta de material. Para P. ovis foi realizada através de coleta do cerúmen com auxílio de zaragatoas efetuadas nas orelhas e para por L. gibbus foi realizada coleta de pelos nas regiões do pescoço dorsal, lombar direita, lombar esquerda, cauda ventral e abdômen ventral. A avaliação da eficácia e a avaliação clínica das lesões, mensuradas em escores (grau 0 a 4) foi realizada nos dias 0, +3, +7, +14, +21, +28 e + 35, após o tratamento. Foi observada a eficácia de 100% no controle de P. ovis a partir do dia +7 e para L. gibbus a partir do dia +14, mantendo-se negativos até o final do período experimental. O escore da lesão das orelhas do grupo tratado regrediu a partir do dia +14 e no dia +21 todos os animais atingiram grau 0. No grupo controle, dois animais apresentaram aumento no escore da lesão das orelhas, um coelho apresentou aumento do escore de grau 1 para 2 e outro coelho de grau 3 para 4. Não foram observadas quaisquer reações adversas nos animais tratados. A ivermectina administrada por via oral em dose única foi eficaz no controle de P. ovis e L. gibbus em coelhos naturalmente infestados

Fishing in the dark: The science and management of recreational fisheries at night

Recreational fshing is a popular activity around the globe, generating billions of dollars in economic beneft based on fsheries in marine and inland waters. In most developed countries, recreational fsheries are managed to achieve diverse objectives and ensure that such fsheries are sustainable. While many anglers fsh during daylight hours, some target fsh species during the night. Indeed, sensory physiology of some species makes them vulnerable to capture at night, while being more difcult to capture during the day. However, night creates a number of challenges for recreational fsheries assessment and management. In some jurisdictions, fshing is prohibited at night (through both effort and harvest controls) or there are specifc restrictions placed on night fsheries (e.g., no use of artifcial lights). Here, we summarize the science and management of recreational fsheries at night covering both inland and marine realms. In doing so, we also provide a review of different angling regulations specifc to night fsheries across the globe, as well as the basis for those regulations. We dis

The nexus of fun and nutrition: Recreational fishing is also about food

Recreational fishing is a popular activity in aquatic ecosystems around the globe using a variety of gears including rod and line and to a lesser extent handlines, spears, bow and arrow, traps and nets. Similar to the propensity to engage in voluntary catch-and-release, the propensity to harvest fishes strongly varies among cultures, locations, species and fisheries. There is a misconception that because recreational fishing happens during non-work (i.e. leisure) time, the nutritional motivation is negligible; therefore, the role of recreational fishing in supporting nutrition (and thus food security) at regional, national or global scales is underappreciated. We consider the factors that influence whether fish will be harvested or released by examining the motives that underlie recreational fishing. Next, we provide an overview of the magnitude and role of recreational fishing harvest in supporting nutrition using regional case-studies. Then, we address issues such as contaminants and parasites that constrain the ability of fish harvested by recreational fishers to be consumed. Although recreational fishing is foremost a leisure activity, the harvest of fish for personal consumption by recreational fishers has contributed and will continue to contribute to human nutrition by providing an accessible, affordable and generally highly sustainable food source, notwithstanding concerns about food safety and possibly overfishing. Attempts to better quantify the role of fish harvested by recreational fishers and the relative contribution to overall food security and personal nutrition will provide resource managers and policymakers the information needed to guide management activities and policy development
