Kan musselextrakt (Mytilus edulis) inducera födosök hos omnivoren ruda, Carassius carassius (Linnaeus, 1758)? / Does mussel meal extract (Mytilus edulis) induce foraging in the omnivorous species crucian carp, Carassius carassius (Linnaeus, 1758)?

Over the last three decades there has been a significant increase in aquaculture production and the demand for farmed fish is predicted to rise further. More fish are being caught to become fishmeal in aquaculture, than for direct human consumption use, while a large number of fish stocks are being depleted. Many popular farmed species are carnivores and thus brought up on a diet consisting of fishmeal and fish oil. However, several studies have shown that several fish species can be brought up on a diet consisting of mussel meal instead of fishmeal. If so, this finding can possibly lead to a more sustainable fishing in the future by reducing the number of wild-caught fish. The purpose of this study has been to examine if mussel meal extract can induce foraging in the omnivorous species crucian carp (Carassius carassius), a commercial fish that is mainly farmed in China. Induced foraging can indicate that crucian carp could become accustomed to mussels, even though mussels are not part of its natural food source. The results revealed that foraging was induced in the crucian carp by conventional feed for carp, the control diet, but not by extract of mussels. / Vattenbruket har ökat markant under de senaste tre decennierna och idag går mer fisk till foderproduktion för fiskodlingar än vad som konsumeras direkt av människan. Detta är problematiskt då många fiskbestånd är utarmade, samtidigt ökar efterfrågan på fisk. Många populära matfiskar är rovfiskar som huvudsakligen matas med fiskbaserat foder. Ett flertal studier har emellertid visat att flera fiskarter potentiellt kan födas upp på blåmusslor (Mytilus edulis) istället för fiskbaserat foder. Foder som huvudsakligen baseras på musslor kan därför i framtiden möjligen bidra till att minska överexploatering av fisk. Denna studie undersökte om musselextrakt kan inducera ett födosök hos omnivoren ruda (Carassius carassius), som idag odlas och används som matfisk framförallt i Kina. I så fall kan det indikera att ruda möjligen kan vänjas vid musslor, trots att det inte ingår i fiskens naturliga föda. Resultaten i studien visade att ett födosök inducerades hos ruda gentemot extrakt av vanligt karpfoder, kontrollsubstansen, men inte gentemot musselextrakt.

The communication process between those patients and the health staff demands constant evaluation on their perception. Recent studies have indicated possibilities of flaws in classifying patients in coma and they have questioned the excessive faith that has been placed on technological devices. Therefore, we propose here the investigation of the primary communication of patients in coma through olfaction, making use of an interdisciplinary study involving communication and health sciences. This study is in accordance with the studies of Semiotics of Culture as well as with the advances in the field of medical research which suggest changes of the established paradigm for the diagnose of those patients. The objective of this study is identifying from olfaction stimulation any probable evidence of communication of patients in coma, by reading and interpreting any possible physiological alterations such as electroencephalographic recording, blood pressure, heart rate and oxygen blood saturation, associated to the observation of subjective signs emitted by the body, from face and body expressions, searching for a possible triggering of the olfactory memory. The physiological responses of patients in coma were compared to those of outpatients. As to face the lack of meaningful statistic alterations on patients in coma, the outpatients were called to take a central role on this present study. Yet, the qualitative analysis makes it possible to imply that the primary responses delivered by the body of the patients in coma might be considered as communication when submitted to olfactory stimulation carried by the combination of other stimuli sensitive to the senses. This interdisciplinary study points to the need of creating between the fields of communication and health an essential link toward the studies of the human body. The theoretical framework was built around the following authors: A. R. Luria (1966, 1979, 1982, 1991), Oliver Sacks (1988, 2013), Edgar Morin (1973, 1996), Gerald M. Edelman (1992), Norval Baitello Jr. (1997, 2005, 2012), F. S. Machado (2006), Hawkes and Doty (2009), Jox et al. (2012), E. Delamonica (1984) among others / A presente tese é uma reflexão sobre a comunicação do corpo em coma em uma unidade de terapia intensiva. O processo de comunicação dessespacientes com a equipe de saúde requer avaliações constantes de sua percepção. Estudos recentes apontam possibilidades de falhas na classificação dos pacientes em coma e questionam a confiança demasiada que se deposita em aparelhos tecnológicos. Dessa forma, propõe-se a investigação da comunicação primária desses pacientes, através do sentido do olfato, por meio de um estudo de caráter interdisciplinar, envolvendo comunicação e as ciências da saúde. Este trabalho está em consonância com os estudos da Semiótica da Cultura e com os avanços na área da pesquisa médica, que sugerem mudanças no paradigma estabelecido para o diagnóstico desses pacientes.O objetivo deste estudo foi identificar, a partir do estímulo olfativo, indícios do processo de comunicação do paciente em coma, através da leitura e da interpretação de possíveis alterações fisiológicas, como registro eletroencefalográfico, pressão arterial, frequência cardíaca e percentual de saturação de oxigênio no sangue, associados à observação de sinais subjetivos emitidos pelo corpo, por meio de expressões faciais e corporais, buscando-se uma possível ativação da memória olfativa. As respostas fisiológicas dos pacientes em coma foram comparadas com as repostas fisiológicas dos pacientes ambulatoriais. A ausência de alterações estatísticas significativas nos pacientes em coma fez com que os pacientes do grupo ambulatorial assumissem um papel central no desenrolar deste estudo. Já a análise qualitativa permite inferir que as respostas primárias apresentadas pelo corpo do paciente em coma, submetido ao estímulo olfativo, podem ser interpretadas como comunicação quando carregadas pela combinação de outros estímulos sensíveis aos órgãos do sentido. Este estudo interdisciplinar aponta para a necessidade de se estabelecer, entre as áreas de comunicação e de saúde, um elo essencial para os estudos sobre o corpo. O quadro teórico assenta-se nos autores: A. R. Luria (1966, 1979, 1982, 1991), Oliver Sacks (1988, 2013), Edgar Morin (1973, 1996), Gerald M. Edelman (1992), Norval Baitello Jr. (1997, 2005, 2012), F. S. Machado (2006), Hawkes e Doty (2009), Jox et al. (2012), E. Delamonica (1984) entre outros
