Item Acompanhamento e relato das atividades desenvolvidas no Laboratório de Experimentação de Organismos Aquáticos(2019) Santos, Wagner Soares; Falcon, Dario Rocha; http://lattes.cnpq.br/9816735154471425Item Assistência técnica e extensão pesqueira no estado de Pernambuco: estratégias, ações e perspectivas para a pesca artesanal(2019) Costa, Tacila Kayla Pereira da; Falcon, Dario Rocha; http://lattes.cnpq.br/9816735154471425; http://lattes.cnpq.br/4531854246625021Artisanal fishing is manifested by the diversity and complexity of subjects, environments, vessels, techniques, fishing gear and communities' way of life. Technical assistance services for small-scale fishing were constructed based on a fishing extension that was / is similar to the rural extension of Brazil, driven by methodological interventions outlined by discontinuous public policies. The objective of this work was to reflect on the technical assistance and fishing extension for artisanal fishing in the sertão of the State of Pernambuco. Eight interviews were conducted with the help of a semistructured script and open questions with managers and leaders of artisanal fishing in the State of Pernambuco. The lack of sensitivity to artisanal fishing is evident among a large number of professionals working with ATER, much fruit of the construction of knowledge within universities, which end up directing these future professionals to the segment that the market indicates, in this case, the aquaculture, and / or the institutional planning of ATER institutions, which end up valuing the segment that gives the state more economic return. The fact is that in the context of fishing extension, the technical follow-up of artisanal fishermen and fishermen is secondary, either in the valuation of aquaculture or in the ambit of social organization.Item Influência da tecnologia de biofloco na qualidade de água e desenvolvimento da larva de tilápia do Nilo (Oreochromis niloticus)(2019) Santos, Wagner Soares; Falcon, Dario Rocha; http://lattes.cnpq.br/9816735154471425The present work evaluated the cultivation of nile tilapia larva (Oreochromis niloticus) in bioflake technology. The cultivation of Nile tilapia larvae in bioflake technology was carried out at the Aquatic Organisms Experimentation Laboratory (LEOA), of the Federal Rural University of Pernambuco (UFRPE), during the period of 28 days. A completely randomized design was adopted with three treatments: bioflake and feed (BFT), clear water with feed (ACD) and non-feed bioflake (BFTs), with four replications per treatment. We used 12 tanks with a useful volume of 15 L of water. Larvae with initial weight 0.001 g were fed ration formulated according to the requirement for the species and processed in the LIONA, with a trawling frequency of 6 times a day and feeding rate of 10 of biomass. Fertilization stemming from daily molasses was performed to maintain the 15:1 (C:N) ratio. L-1), conductivity (S. cm-1), salinity (g L-1), pH, total dissolved solids, total ammoniacal nitrogen (N-NAT), nitrite (N-NO2), nitrate (N-NO3), inorganic phosphate (P-PO4), turbidity, sedimentable solids (SS) and alkalinity. Zootechnical performance of larvae was evaluated using the variables final weight (mg), survival (), apparent feed conversion factor (FCA), TCA (/ day), and condition factor (K). In the observation of the difference between treatments according to the decriminalanalysis of correct allocation of the group that was 96.80 with P < 0.0001. The best results were achieved in bft and acd treatments, when compared to bioflake without feed. Bioflake technology is a good alternative for the cultivation of nile tilapia larva, allowing the reduction of feed use, since productive performance was similar to the treatment that used clear water and feed.
