Conhecimento ecológico tradicional da ictiofauna pelos quilombolas no Alto Guaporé, Mato Grosso, Amazônia meridional, Brasil

Resumo O objetivo desta pesquisa foi estudar o conhecimento ecológico tradicional (CET) relacionado à pesca feita por grupo étnico autoidentificado como quilombola, por meio da análise de fatores que influenciam o consenso cultural e as técnicas da pesca artesanal. Participaram 24 homens e sete mulheres dos quilombos Retiro, Boqueirão, Casalvasco e Manga. Os métodos de amostragem utilizados foram: bola de neve, lista livre e observação participante. Os resultados incluem 47 etnoespécies (46 peixes e um réptil). O consenso cultural é composto por: Hoplias malabaricus, Cichla sp., Pseudoplatystoma fasciatum, Astronotus ocellatus, Satanoperca pappaterra, Brycon cephalus, Piaractus mesopotamicus, P. corruscans, Pimelodus sp., Colossoma macropomum, Pygocentrus nattereri, Mylossoma aureum, Astyanax sp. e Leporinus freiderici. Embora tenha sido maior a riqueza do conhecimento entre pessoas que residiram temporariamente em outros estados brasileiros, este aspecto não esteve relacionado à idade dos entrevistados. A manutenção e a transmissão de CET é propiciada por contato diário com peixes e com o rio desde criança, bem como por observação das práticas de pesca em grupo. O CET é parte da identidade e representa uma herança cultural que deve ser valorizada. É necessária a participação desses atores sociais nos planos de decisão e de gerenciamento de áreas protegidas.

O objetivo deste trabalho foi avaliar o efeito da alimentação na resistência ao estresse e no crescimento de larvas das espécies de peixes neotropicais: Astronotus ocellatus (Oscar), Piaractus mesopotamicus (pacu) e Pseudoplatystoma coruscans (pintado). As larvas receberam diferentes tipos de alimentos (Artemia sp., larvas de Colossoma macropomum e dieta artificial Fry Feed Kyowa). Foram realizados testes de exposição ao ar e a taxa de sobrevivência, determinada 24 horas depois. A fim de avaliar o crescimento, medidas de peso foram realizadas em larvas dos diferentes tratamentos. Larvas de A. ocellatus alimentadas com náuplios de Artemia sp. apresentaram tendência de maior peso e resistência ao estresse, quando comparadas com o uso de dieta artificial. Larvas de P. mesopotamicus apresentaram melhores valores de peso e taxas de resistência ao estresse, quando alimentadas com Artemia sp. ou alimentação mista (Artemia sp. + dieta artificial). Em P. coruscans, o uso de larvas forrageiras resultou em indivíduos mais resistentes aos testes de exposição ao ar do que os que receberam apenas Artemia sp. Valores de peso, nos dois manejos alimentares, foram semelhantes entre si. O alimento vivo desempenha importante atuação no crescimento em peso e na melhora da resistência ao estresse das espécies estudadas.

O objetivo deste trabalho foi determinar os teores de colesterol e lipídios totais na porção comestível (tecido muscular) de seis espécies de peixes capturados na região pantaneira do Estado de Mato Grosso do Sul. As espécies estudadas foram o pacu ( Piaractus mesopotamicus), a piranha ( Pygocentrus nattereri), o dourado ( Salminus maxillosus), a piraputanga ( Brycon orbigynanus), o piauçu ( Leporinus macrocephalus) e o pintado ( Pseudoplatystoma coruscans). Usou-se o método colorimétrico de BOHAC et al. para determinação do colesterol e o da extração com solvente orgânico e gravimetria para lipídios totais. Quanto aos teores de lipídios totais, os valores médios obtidos para as seis espécies de peixes estudadas enquadraram-se na faixa de 1,0 a 6,7 g/100 g de tecido muscular dos peixes, sendo a menor concentração apresentada pelo pintado e a maior pela piraputanga. A concentração de colesterol, em mg/100 g de tecido muscular (base úmida), foi mais alta para o dourado (107,4 mg/100 g) e mais baixa para o pintado (51,5 mg/100 g). CHOLESTEROL LEVELS AND TOTAL LIPIDS IN SIX SPECIES OF FISH CAPTURED IN PANTANAL REGION OF MATO GROSSO DO SUL STATE Abstract The objective of this work was to determine the cholesterol and total lipids content in the edible portion (muscular tissue) of six species of fish, captured in the Pantanal region of Mato Grosso do Sul State (Brazil). The studied species were the pacu ( Piaractus mesopotamicus), the piranha (Pygocentrus nattereri), the dourado ( Salminus maxillosus), the piraputanga ( Brycon orbigynanus), the piauçu ( Leporinus macrocephalus) and the pintado ( Pseudoplatystoma coruscans). The method for determination of cholesterol was the colorimetric of BOHAC et al. and for the total lipids was the extraction method with organic solvent and gravimetry. With relationship to the values of total lipids, the average content obtained for the six species of studied fish were in the range of 1,0 to 6,7 g/100 g of muscular tissue of the fish, and the pintado presented smaller concentration and the piraputanga was revealed as the largest lipid source. The cholesterol concentration, in mg/100 g of muscular tissue (raw base) was higher for the dourado (107,4 mg/100 g) and lower for the pintado (51,5 mg/100 g).

AbstractFive species of Urocleidoides (one new) and two new species of Constrictoanchoratus n. gen. are described in this study. All were collected from the gills of Hoplias malabaricus (Characiformes: Erythrinidae) captured in six localities of coastal rivers of the north-eastern sector the State of Pará (Oriental Amazon): Urocleidoides brasiliensis Rosim, Mendoza-Franco & Luque, 2011; Urocleidoides bulbophallus n. sp.; Urocleidoides cuiabai Rosim, Mendoza-Franco & Luque, 2011; Urocleidoides eremitus Kritsky, Thatcher & Boeger, 1986; Urocleidoides malabaricusi Rosim, Mendoza-Franco & Luque, 2011; Constrictoanchoratus lemmyi n. gen. n. sp.; and Constrictoanchoratus ptilonophallus n. gen. n. sp. This is the first reported occurrence of the four previously described species of Urocleidoides parasitizing H. malabaricus from streams in the Oriental Amazon Basin. The analysis of voucher specimens of U. eremitus parasitizing the gills of H. malabaricus from the Upper Paraná River floodplain in the limits of States of Paraná and Mato Grosso do Sul, Brazil, indicates that these specimens are members of a new species of Urocleidoides, described here as Urocleidoides paranae n. sp. Constrictoanchoratus n. gen. is proposed for the species with a male copulatory organ sclerotized, coiled, clockwise; ventral anchor with elongate superficial root, inconspicuous deep root; dorsal anchor with inconspicuous roots, and a constriction at the intersection between the shaft and the point. The host–parasite diversity scenario and host specificity of the species of Constrictoanchoratus n. gen. and Urocleidoides from the gills of H. malabaricus are also discussed in this study.

The objective of this study was to obtain the growth curve of selectively bred tambaqui (Colossoma macropomum) reared in different environments. The experiment was carried out in the municipalities of Santo Antônio de Leverger (Mato Grosso – MT) and Campo Grande (Mato Grosso do Sul – MS), Brazil, over 431 days. Weight and morphometric traits of two families (A and B) from the second generation of selective breeding (G2) were measured every 30-45 days. The Gompertz regression model was used to obtain the growth curves. The production performance of both families and the interaction between families and locations (genotype × environment) were evaluated by analysis of variance considering the family (A and B), location (MT and MS), family × location interaction and error as variation factors. The asymptotic value (parameter A) obtained for weight and morphometric traits (except head length) was higher (P<0.05) in MT (weight of families A and B: 2279.6 g) than in MS (weight of family A: 1400.0 g; weight of family B: 1600.0 g). Family B showed better production performance in MS. There was a genotype × environment interaction effect on weight, body length and standard length. The two families have distinct growth patterns in different production environments. Family B has better growth performance in the environment with lower temperatures (MS).

Cross Amplification

ABSTRACT: Brycon orbignyanus, popularly known in Brazil as piracanjuba, is a fish with great economic value but whose natural population drastically decreased in number during the last years. In this context, genetic variability studies of natural stocks and in restocking programs are fundamental for the adoption of conservation measures. Current analysis verifies the cross-amplification of heterologous primers in B. orbignyanus. Fifty-two primers of the species Brycon opalinus, Brycon hilarii, Brycon insignis, Prochilodus sp., Piaractus mesopotamicus, Colossoma macropomum and Oreochromis niloticus were tested. Primers with the best reproducibility were applied to a sample of 20 individuals and the genetic parameters were calculated. Nine primers provided good results for cross-amplification with B. orbignyanus, involving (BoM5 and BoM13) of Brycon opalinus, (Bh5, Bh6, Bh8, Bh13 and Bh16) of Brycon hilarii, (Bc48-10) of Brycon insignis and (Par80) of Prochilodus argenteus. Primers of Piaractus mesopotamicus, Colossoma macropomum and Oreochromis niloticus failed to provide amplification or provided non-specificity. Results demonstrated the possibility of using primers of different species and genera of B. orbignyanus, facilitating genetic studies on the species.

Herein we describe spawning and egg guarding in the erythrinid fish Hoplias malabaricus observed in the southern Pantanal (19° 34' S and 57° 00' W), state of Mato Grosso do Sul, Brazil. Nests were depressions built on sandy soil in flooded areas, and contained a mean of 8,197 ± 2,204 eggs (N = 4); the mean diameter of eggs was 1.44 ± 0.09 mm (N = 400). Among 11 nests observed, eight were guarded by males and three by the pair. One male remained in the nest for six days, and two pairs remained guarding the eggs for at least three days before being captured. Females (N = 2) captured in the nest contained oocytes in their ovaries. Our observations suggest that male parental care is the normal form of parental care in H. malabaricus, but biparental care also seems to occur.

The aim of this study was to evaluate the tegument, musculature and mesentery of 102 specimens of Hoplerytrinus unitaeniatus, 104 of Hoplias malabaricus and 101 of Pygocentrus nattereri, from Arari Lake, Marajó Island, State of Pará, Brazil. Were identified the nematodes Contracaecum sp., Eustrongylides sp. and Procamallanus sp. Contracaecum sp. was the most prevalent, with rates of 84.31% (H. unitaeniatus), 95.19% (H. malabaricus), and 89.11% (P. nattereri). The highest prevalences of Eustrongylides sp. occurred in H. unitaeniatus (56.86%) and H. malabaricus (53.84%). Procamallanus sp. was only collected in the mesentery. Specimens of Eustrongylides sp. collected from the musculature were 91.9% of its population. Among the nematodes found in the mesentery, 98.34% were Contracaecum sp. with a mean intensity (MI) of 7.92 ± 8.11 (H. unitaeniatus), 8.49 ± 8.34 (H. malabaricus) and 7 ± 6.40 (P. nattereri). Contracaecum sp. presented the highest MI (8.49 ± 8.34) and mean abundance (8.09 ± 8.34). The highest MI values were observed in the mesentery. Eustrongylides sp. presented MI of 2.65 ± 3.21 (H. unitaeniatus), 3.41 ± 3.27 (H. malabaricus) and 2.17 ± 1.18 (P. nattereri). Nematodes with zoonotic potential that were found with high prevalence, shows the importance of actions by the health authorities.
