Geographical and morphological variation within and between colour phases in Coris julis (L. 1758), a protogynous marine fish

The possible differences between sexes in patterns of morphological variation in geographical space have been explored only in gonochorist freshwater species. We explored patterns of body shape variation in geographical space in a marine sequential hermaphrodite species, Coris julis (L. 1758), analyzing variation both within and between colour phases, through the use of geometric morphometrics and spatially-explicit statistical analyses. We also tested for the association of body shape with two environmental variables: temperature and chlorophyll a concentration, as obtained from time-series of satellite-derived data. Both colour phases showed a significant morphological variation in geographical space and patterns of variation divergent between phases. Although the morphological variation was qualitatively similar, individuals in the initial colour phase showed a more marked variation than individuals in the terminal phase. Body shape showed a weak but significant correlation with environmental variables, which was more pronounced in primary specimens.

Atlantic-Mediterranean and within-Mediterranean molecular variation in Coris julis (L. 1758) (Teleostei, Labridae)

Sequence variation in the mitochondrial control region was studied in the Mediterranean rainbow wrasse (Coris julis), a species with pronounced pelagic larval phase inhabiting the Mediterranean Sea and the adjacent coastal eastern Atlantic Ocean. A total of 309 specimens from 19 sampling sites were analysed with the aim of elucidating patterns of molecular variation between the Atlantic and the Mediterranean as well as within the Mediterranean Sea. Phylogeographic analyses revealed a pronounced structuring into a Mediterranean and an Atlantic group. Samples from a site at the Moroccan Mediterranean coast in the Alboran Sea showed intermediate frequencies of “Mediterranean” and “Atlantic” haplotypes. We recognised a departure from molecular neutrality and a star-like genealogy for samples from the Mediterranean Sea, which we propose to have happened due to a recent demographic expansion. The results are discussed in the light of previous studies on molecular variation in fish species between the Atlantic and the Mediterranean and within the Mediterranean.

Population structure, mortality and growth of Pinna nobilis Linnaeus, 1758 (Mollusca, Bivalvia) at different depths in Moraira bay (Alicante, Western Mediterranean)

An investigation to characterize the causes of Pinna nobilis population structure in Moraira bay (Western Mediterranean) was developed. Individuals of two areas of the same Posidonia meadow, located at different depths (A1, -13 and A2, -6 m), were inventoried, tagged, their positions accurately recorded and monitored from July 1997 to July 2002. On each area, different aspects of population demography were studied (i.e. spatial distribution, size structure, displacement evidences, mortality, growth and shell orientation). A comparison between both groups of individuals was carried out, finding important differences between them. In A1, the individuals were more aggregated and mean and maximum size were higher (A1, 10.3 and A2, 6 individuals/100 m(2); A1, x = 47.2 +/- 9.9; A2, x = 29.8 +/- 7.4 cm, P < 0.001, respectively). In A2, growth rate and mortality were higher, the latter concentrated on the largest individuals, in contrast to A1, where the smallest individuals had the higher mortality rate [A1, L = 56.03(1 - e(-0.17t)); A2, L = 37.59(1 - e(-0.40t)), P < 0.001; mean annual mortality A1: 32 dead individuals out of 135, 23.7% and A2: 16 dead individuals out of 36, 44.4%, and total mortality coefficients (z), z(A1(-30)) = 0.28, z(A1(31-45)) = 0.05, z(A1(46-)) = 0.08; z(A2(-30)) = 0.15, z(A2(31-45)) = 0.25]. A common shell orientation N-S, coincident with the maximum shore exposure, was observed in A2. Spatial distribution in both areas showed not enough evidence to discard a random distribution of the individuals, despite the greater aggregation on the deeper area (A1) (A1, chi(2) = 0.41, df = 3, P > 0.5, A2, chi(2)= 0.98, df = 2 and 0.3 < P < 0.5). The obtained results have demonstrated that the depth-related size segregation usually shown by P. nobilis is mainly caused by differences in mortality and growth among individuals located at different depths, rather than by the active displacement of individuals previously reported in the literature. Furthermore, dwarf individuals are observed in shallower levels and as a consequence, the relationship between size and age are not comparable even among groups of individuals inhabiting the same meadow at different depths. The final causes of the differences on mortality and growth are also discussed.

Age and growth of Mugil cephalus (Linnaeus, 1758) (Perciformes: Mugilidae) in Bonny Estuary

The age and growth of Mugil cephalus was investigated in Bonny Estuary, Nigeria, from January, 1995 to December, 1996. Length-weight relationships were isometric with length exponents of 2.84 (males), 2.90 (females) and 2.88 (overall). Modal length at age were 12.0cm, 20.9cm, 25.0cm, 28.4cm and 30.2cm TL for ages 0+, 1+, 2+, 3+ and 4+ respectively. Corresponding total weights were 20.01g, 78.93g, 173.12g, 217.61g and 247.50g, respectively. Asymptotic length (Lo) was estimated 33.2cm TL, asymptotic weight (W sub(o)) was 484g, growth coefficient K=0.55847 super(-1) and hypothetical age at zero length To = 0.152yr. Longevity, Tmax, was 5.0yr, length and weight growth performance indices were Q super(1)=2.79 and Q = 1.44, respectively. Total mortality, natural mortality and fishing mortality were z = 1.02yr super(-1), M=0.607yr super(-1) and F=O. 3129yr super(-1), respectively. The exploitation ratio E was 0.4048 and exploitation rate U = 0.2302yr super(-1)

Some ecological roles of Hippopotamus (Hippopotamus amphibious Linn. 1758) in fish production: possibilities for integrated fish-cum Agric production system

The common hippopotamus (Hippopotamus amphibious Linn. 1758) contributes to the productivity of aquatic systems where it lives. This paper reviews ecological roles of the hippo in this regard. Desk review of available literature information complemented with field observations were employed in the data collection. The ecological roles of the common hippopotamus being presented draw examples from East, West, Central and South African sub regions. The nutritional importance of the amphibious hippopotamus to rural communities was highlighted. In Southern Ethiopia, the Bodi, Bacha and Mura tribes eat hippo meat and this has led to severe hunting consequences on the wild populations of the animal. The important relationships between the hippopotamus and fish were presented. Hippopotamuses usually defecate in water and their excrements enrich the nutrients in the water resulting in favourable conditions for large fish populations. Some fish, including Labeo spp. were observed to feed on the micro-organisms and algae that grow on the skin of the hippotamus. A strong case was made for hippo-cum-fish integrated farm development in Nigeria based on ecological relationships so observed between the amphibious mammals and fish. This is one of the meeting points of fisheries and wildlife management that should be exploited for the benefits of the teeming Nigerian population

Effect of darting phenomenon of African catfish Heterobranchus longifilis (Burchell 1822) on growth performance of Nile tilapia: Oreochromis niloticus (Linnaeus, 1758)

Replicate Ponds of 0.02ha stocked at 500 catfishes with 20,000 tilapia/ha were used to assess growth performance of O.niloticus, average weight 50.4g with (i) darted catfish; H.longifilis (shooters) average weight 60.3g (ii) non-shooters of H.longifilis, average weight 35.4g. Final mean weight, mean growth rate, specific growth rate and food conversion ratio were 499.5g 26g/day, 1.36% and 5.58% respectively for O.niloticus stocked with longifilis (shooters and 440.4g 2.3g/day 1.23% and 5.58% respectively for O.niloticus stocked withH.longifilis (non- shooters) and 246.9g, 1.2g/day, 0.93, 6.30% respectively for tilapia in monoculture. The least growth was noted for O. niloticus in monoculture while the best growth was recorded O. niloticus in polyculture with darted catfish

Avaliação regional da contaminação por hidrocarbonetos policíclicos aromáticos (HPAs) na região costeira do sudeste do Brasil usando mexilhões (Perna perna Linneaus 1758) como biomonitores

O objetivo do presente trabalho foi avaliar a presença e a distribuição de hidrocarbonetos policíclicos aromáticos (HPAs) em mexilhões coletados em 23 estações, divididas em três regiões: (i) cultivos localizados no Estado do Rio de Janeiro (7 estações) e em Ubatuba/SP (1 estação); (ii) áreas costeiras no Estado do Rio de Janeiro (7 estações) e (iii) na Baía de Guanabara/RJ (8 estações). Os HPAs foram determinados em triplicata de cada estação, sendo cada réplica formada por uma média de 10 indivíduos, através de cromatografia em fase gasosa acoplada a espectrometria de massas (GC/MS), totalizando 38 compostos entre parentais e alquilados. A concentração média do total de HPAs nos cultivos, excluindo o cultivo de Mombaça (Ilha Grande), foi de 24,7 22,3 ng g-1, para as áreas costeiras foi de 89,7 25,8 ng g-1 e para a Baía de Guanabara, 760,9 456,3 ng g-1. Esses resultados indicam que os cultivos (exceto Mombaça) e as áreas costeiras selecionadas apresentam baixos níveis de contaminação. Já na Baía de Guanabara, os resultados foram comparáveis a dados pretéritos e confirmam o estado de degradação ambiental da baía. Na amostra coletada no cultivo de Mombaça, a alta concentração do total de HPAs (584 ng g-1) e a predominância de compostos alquilados sobre parentais sugerem contaminação relativamente alta por hidrocarbonetos petrogênicos. A análise de agrupamento, considerando o total de HPAs, confirmou a separação entre as três áreas coletadas, mas com algumas exceções: (i) o cultivo de Mombaça assemelha-se ao grupo da Baía de Guanabara; (ii) a estação da Praia Vermelha, na saída da Baía de Guanabara, se assemelha com áreas costeiras fora da baía; (iii) as estações Ilha Redonda, Ilha Comprida e Pontal, distantes mais de 5 km da costa, se agruparam com os cultivos. Somente nas amostras da Baía de Guanabara foi possível avaliar a origem dos HPAs através da análise de componentes principais (PCA). A maioria das amostras da baía apresenta contaminação por fontes mistas de hidrocarbonetos, e apenas na praia Vermelha o aporte pirolítico é mais significativo. Por fim, ressalta-se que os níveis de HPAs nos mexilhões das três áreas ficaram abaixo de valores de referência exigidos internacionalmente para o consumo humano. No entanto, é necessário uma análise de risco específica para melhor compreender a qualidade do mexilhão para consumo humano, particularmente os da Baía de Guanabara.

Courtship and spawning behaviors of carangid species in Belize

Many species of reef f ish agg regate seasonally in large numbers to spawn at predictable times and sites (Johannes, 1978; Sadovy, 1996; Domeier and Colin, 1997). Although spawning behavior has been observed for many reef fish in the wild (Wicklund, 1969; Smith, 1972; Johannes, 1978; Sadovy et al., 1994; Aguilar Perera and Aguilar Davila, 1996), few records exist of observations on the courtship or natural spawning for the commercially important family Carangidae (jacks) (von Westernhagen, 1974; Johannes, 1981; Sala et al., 2003). In this study, we present the first observations on the natural spawning behavior of the economically-valuable permit (Trachinotus falcatus)(Linnaeus, 1758) from the full to new moon period at reef promontories in Belize, with notes on the spawning of the yellow jack (Carangoides bartholomaei) (Cuvier, 1833), and the courtship of five other carangid species.

Eusébio de Queirós: chefe de polícia da Corte (1833-1844)

Nesta dissertação apresentamos uma análise da trajetória de Eusébio de Queirós no período em que ele ocupava o cargo de chefe de polícia da Corte (1833-1844), momento de grande turbulência social no Império, e consolidação das posições do Regresso Conservador. Mostramos como Eusébio de Queirós se precipitou sobre o "vazio" de atribuições que caracterizava a função de chefe de polícia, tornando-se um articulador da administração da justiça na Corte, após assumir a direção de uma Secretaria de Polícia da Corte com uma estrutura precária, em meio às discussões acerca do regime policial estabelecido com a adoção do Código de Processo Criminal de 1832. A ideia de que no compartilhamento da informação entre as autoridades estava a pedra angular da segurança pública foi uma constante na trajetória de Queirós, exemplificados na abordagem dada à Revolta dos Malês (1835) e às Revoltas Liberais de 1842. Esta pesquisa trabalha uma entre as possíveis caracterizações de Eusébio de Queirós, considerando as implicações de ordens biográfica e historiográfica, procurando problematizar por meio de uma trajetória específica aspectos que circundam o processo de construção do Estado nacional no Brasil.
