The present study intended to evaluate the effects of early introduction of inert diet in lipid digestibility and metabolism of sole, while larval feed intake, growth and survival were also monitored. Solea senegalensis larvae were reared on a standard live feed regime (ST) and co-feeding regime with inert diet (Art R). Trials using sole larvae fed with Artemia enriched with two different lipid emulsions, containing glycerol tri [1-, were performed at 9 and 17 days after hatching (DAH) to study lipid utilization. Co-feeding did not affect sole survival rates (ST 59.1 ± 15.9%; Art R 69.56 ± 9.3%), but was reflected in significantly smaller final weight at 16 DAH (ST 0.71 ± 0.20; Art R 0.48 ± 0.14 mg). Higher feed intake was observed in sole larvae fed on Artemia enriched with labeled PL at 9 DAH but not at 17 DAH. At 17 DAH, the smaller larvae (Art R treatment) ingested proportionally more Artemia in weight percentage, independently of enrichment. At 9 DAH lipid digestibility was equal among treatments and higher than 90%, while at 17 DAH it was higher in ST treatment (around 73%) compared to the Art R group (around 66%). Lipid retention efficiency at 9 DAH was higher in the Art R treatment, reaching values of 50%, while these values almost duplicated at 17 DAH, ranging up to 80% in both treatments without significant differences. These results show that co-feeding of live feed and inert diet from first-feeding in Senegalese sole has a toll in terms of growth and lipid digestibility but does not seem to compromise lipid metabolic utilization.

We investigated the effect of Alpinia zerumbet essential oil on the quality and shelf life of tambaqui (Colossoma macropomum) fillets stored under refrigeration (10.0 ± 0.5 °C) for 14 days. The treatments were A. zerumbet essential oil at 0.75% v v-1 (AEO 0.75%), A. zerumbet essential oil at 1.5% v v-1 (AEO 1.5%) and a control (no essential oil). The sample quality and shelf life were determined by the total psychrotrophic count (TPC) and chemical parameters (pH, total volatile basic nitrogen, centesimal composition and thiobarbituric acid reactive substances - TBARS) at zero, seven and 14 days of storage time. The TPC decreased significantly (p < 0.05) with an A. zerumbetessential oil level of 1.5% until seven days of storage. The concentration of A. zerumbet essential oil at 0.75% resulted in lower pH, TBARS, and TVBN values in comparison with the other treatment and the control. Thus, A. zerumbet essential oil was efficient in extending the shelf life of refrigerated tambaqui fillets up to approximately seven days.

renda e trabalho às comunidades que vivem de sua pesca. Seu consumo é um dos atrativos da culinária do Nordeste do país, proporcionando sustentação a bares e restaurantes temáticos bastante apreciados pelos turistas. Os caranguejos não vendidos pelos pescadores ou pelos comerciantes são processados artesanalmente para extração da carne ou massa de caranguejo. Este trabalho teve como propósito diagnosticar a situação socioeconômica dos trabalhadores envolvidos nesta atividade, bem como as condições higiênico-sanitárias de processamento, manipulação e acondicionamento da carne de caranguejo em locais chamados de "quebradeiras", verificando-se os parâmetros microbiológicos do produto. Foram avaliados oito locais de beneficiamento de carne de caranguejo, por meio de observações visuais, registros fotográficos, aplicação de questionário e entrevista semiestruturada. Amostras de carne de cada local foram coletadas para análise microbiológica (Coliformes termo tolerantes, Salmonella sp., estafilococo). Os resultados demonstraram um padrão semelhante de infraestrutura e práticas para o beneficiamento da carne nos diferentes locais. Foi constatado baixo nível de escolaridade dos quebradores, baixa renda familiar e pouco conhecimento sobre contaminação e boas práticas na manipulação de alimentos. Ainda assim, os resultados microbiológicos das amostras de carne de caranguejo demonstraram um padrão sanitário satisfatório.

The Ucides cordatus mangrove crab is one of the most economically important crustaceans in Brazil, being a source of income and work for the fishing communities. Its consumption is one of the Northeastern cuisine attractions, supporting the thematic restaurants greatly appreciated by tourists. Crabs not sold by fishermen or traders are processed locally for meat or pasta crab extraction. This work aimed to diagnose the socioeconomic situation of the workers involved in this activity, as well as the hygienicsanitary conditions of processing, handling and packaging of crabmeat in places called

The century-old mangrove crab Ucides cordatus Linnaeus, 1763 harvesting is a traditional activity of Northeastern Brazilian coastal communities, who use it as food, source of income and cultural reference. The extractivism and marketing of this crustacean is essential for the socioeconomic development of the states of Maranhão, Piauí and Ceará. The aim of this study was to carry out the monitoring of harvesting and landing of the mangrove crab in Ilha Grande, PI. Interviews were conducted with crab gatherers and transporters to obtain information about harvesting, landed volume, market price and destination of commercialized crab. The main capture spots were located at the Maranhão part of the Parnaíba River Delta. Crab gatherers are active 5.07 times a week and spend an average of 6 hours in mangrove. The average number of crabs collected per gatherer/day was 77.0. The quantity landed in daytime period was 63,628 crabs/month, totalizing 714,543 crabs/ year. The average price traded was USD 0.19/crab. The production chain
