Última Longer is not always better: The influence of beach seine net haul distance on fish catchability Rev. Bras. Zool. Lombardi,Pryscilla Moura; Rodrigues,Fábio Lameiro; Vieira,João Paes. The aim of this study was to compare the influence of different haul distances of a codend beach seine on the catchability of fish in a surf zone. Two different surf zone sites (A and B) at the Cassino Beach (Rio Grande do Sul, Brazil) were sampled at three different distances, parallel to the beach (30, 60, and 90 m). Starting 40 m from the beach line, diagonal distances of approximately 50, 70, and 100 m were swept. The total CPUE and CPUA haul distances are compatible with a declining trend in catch rates with increased haul distance at both sites. However, statistically significant differences were observed only for the short distance CPUA (50 m) in relation to the other haul distances at one of the sites sampled. Two fish size groups were observed (TL... Tipo: Info:eu-repo/semantics/article Palavras-chave: Fish abundance; Fish size; Sampling gears; Surf zone. Ano: 2014 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1984-46702014000100005 Hábito alimentar e osteologia da boca do peixe-rei, Odontesthes humensis de Buen (Atheriniformes, Atherinopsidae) na Lagoa Mirim, Rio Grande do Sul, Brasil Zoologia Rodrigues,Fábio Lameiro; Bemvenuti,Marlise de Azevedo. Gut contents of 304 individuals of the silverside Odontesthes humensis de Buen, 1953 were analyzed using frequency of occurrence (FO%) and gravimetric (P%) methods. A total of 207 individuals (68.1%) had some food itens in the gut, while 97 individuals (31.9%) had empty guts. The silverside Odontesthes humensis has presented a benthic carnivorous diet, preying mainly on molluscs and arthropods. The molluscs Heleobia sp. (FO = 61.35%) and Corbicula fluminea (Müller, 1774) (FO = 57.97%) were the most frequent itens, followed by Neocorbicula limosa (Maton, 1811) (FO = 17.39%). Among the arthropods, the coleoptera insects (FO= 18.84%) were dominant followed by, insect larvae (FO = 6.76%), the crustacean Palaemonetes argentinus Nobili, 1901 (FO = 1.93%) and...

Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-81752001000300015 Análise comparativa entre técnicas morfométricas aplicadas a Odontesthes bonariensis (Valenciennes) e Odontesthes humensis De Buen (Osteichthyes, Atherinopsidae) Zoologia Bemvenuti,Marlise de Azevedo; Rodrigues,Fábio Lameiro. The objective of this study was to compare two different morphometric methodologies - traditional measurements and truss networks - based on two species of silversides, Odontesthes bonariensis (Valenciennes, 1835) and O. humensis De Buen, 1953, to determine which of the methods results in more reliable distinction between groups. The traditional measures do not represent the true fish form because it does not take into account alometric variations or distinct growth stages. The measures with truss networks extend over the fish form thoroughly resulting in complete representation of the fish's body when homologous morphologic points are connected. The two sets of measures used in the principal components analysis resulted in two groups. The first principal...
