| Marine communities in tropical regions contain a great diversity of species that play key roles in ecological processes. The observed bycatch fauna in artisanal fishing for the seabob shrimp Xiphopenaeus kroyeri (Heller, 1862) in the southwest Atlantic exceeds the quantity of commercial shrimp captured. This bycatch has not been previously inventoried extensively in Brazil, particularly in the State of Santa Catarina, where small-scale shrimp fisheries is a traditional activity and dominates the local fishing economy. Six municipalities were sampled three times a month, from 1996 to 2011, yielding 216 species belonging to the bycatch (7 cnidarians, 22 mollusks, 42 crustaceans, 11 echinoderms, and 134 fishes). Bycatch management is a pressing aspect of... |

| The objective of the present study was to analyze diel variation in the abundance and size of the seabob shrimp Xiphopenaeus kroyeri in the Ubatuba region, state of São Paulo, during the year 2000. In each season of the year, collections were made in the day and at night on 9 transects at depths ranging from 2 to 40 m. The estimated shrimp amount was of 28,878 individuals. Although the catch rate was higher during the day (15,853 shrimp), this did not differ significantly from the catch at night (13,025). The catch rate was higher in daytime on most transects, but was higher at night at locations where fine and very fine sand predominated. The majority of juveniles were caught during the day. The mean size (CL) was 14.43 ± 4.02 mm for day and 14.82 ± 4.28... |

| Xiphopenaeus kroyeri is the most exploited shrimp specie along Center-South coast of Santa Catarina State, Brazil, by artisanal fishery. In the period from March/1996 to February/1997, 3965 shrimps were collected (1843 males and 2122 females) sampled by over-trawl, with the depth oscillating between 5 and 15 meters. Xiphopenaeus kroyeri shows seasonal fluctuations in its abundance with higher rates in autumn. The population's average total-length varied between 7.5cm and 9.1cm, and the presence of juveniles was common along the year. The males and females get to the first gonadal maturation with 7.4 cm and 9.0 cm length, respectively; these lengths were reached within 6 and 8 months of age. |

| A pesca artesanal dirigida ao camarão sete-barbas (Xiphopenaeus kroyeri), usando o método de arrasto motorizado com portas, tem sido praticada na costa de Santa Catarina, onde ele gera emprego e renda, e ajuda a manter a tradição cultural tradicional açoriana viva, desde 1960. Com o objectivo de analisar a qualidade e a quantidade das capturas acidentais da ictiofauna, efetuou-se sazonalmente, dois arrastos por isóbata (10-20‑30 m) entre novembro/2009 e agosto/2010, duração de 20 min/cada, velocidade média dois nós e, registrados temperaturas e salinidades da água de fundo. As capturas totalizaram 10868 peixe (208.34 kg), distribuídos em 31 famílias e 62 espécies, com uma proporção de peixe/camarão de 5,19/1 kg. A família mais abundante foi Sciaenidae... |

| Elaboraram-se e caracterizaram-se nutricionalmente dois tipos de silagens fermentadas de resíduos de camarão-sete-barbas (Xiphopenaeus kroyeri), alterando-se as fontes de carboidratos. As silagens foram formuladas com resíduo de camarão, 15% de carboidrato -melaço de cana-de-açúcar (SM) ou varredura da farinha láctea (SF)-, 10% de iogurte, 0,25% de ácido sórbico e 1% de ácido fórmico. Cada silagem foi caracterizada durante a estocagem, por 120 dias, quanto à composição centesimal, nitrogênio não protéico e todas comparadas por meio do teste de digestibilidade in vivo com juvenis de tilápia-do-nilo. Após o 30° dia de estocagem, observou-se que a SM apresentou maior (P<0,05) teor de cinzas (SM= 34,97g.100g-1 e SF= 30,92g.100g-1) e menor teor de matéria... |
