Osteichthyes (mainly includes teleosts), represent the largest and most diverse class of vertebrates in existence today, with about 32,400 species, which is more than the combined total of mammals, birds, amphibians and reptiles. Teleosts are sexually labile which can display an astonishing variety of reproductive modes such as gonochorism, protandry, protogyny, true hermaphroditism, gynogenesis and androgenesis. Successful reproduction of a species mainly depends on organized reproductive strategies including gonadal differentiation/development and gametogenesis. Gonadal development/differentiation is governed by a delicate balance of genetic, hormonal and environmental factors. On the other hand, efficient and regulated gametogenesis is critical for the quality seed production, which is a key area of aquaculture research and development. This book represents collective version of review chapters contributed by eminent scientists all over the world including India. The demand for the fishes is in rise every day, with the improved aquaculture research on controlling gametogenesis and spawning has provided possible options to increase the production, yet, the equilibrium never met. The application of modern molecular biology techniques and tools facilitate scientists to delineate several fundamental questions of endocrinology and reproductive biology, and thus assist in sustainable aquaculture management. Amazing expansion in the number of quality publication and scientific congregation concerning fish reproduction is a witness for the growing importance for the aquaculture research. Our knowledge of sexual plasticity and gamete maturation has been expanded rapidly since the recent advances in sexual development research using model organisms ranging from fishes to mammals. Sexual development research is on the top priority because of its great potential in finding sex determining genes. The recent surge of interest in identifying the mechanisms pertaining to endocrine disruption makes fisheries research to progress in sexual development and gamete maturation studies, which are the two emerging multidisciplinary research fields with wide range of future prospects. This book is a tribute to those investigators who work on sex determination, differentiation, gamete maturation and fish reproductive physiology, who inspired a whole generation of researchers

    Volume 6 • 2018 10.1093/conphys/coy016 Research article Influence of artificially induced light pollution on the hormone system of two common fish species, perch and roach, in a rural habitat Anika Brüning1,2,*, Werner Kloas1, Torsten Preuer1 and Franz Hölker1 1Leibniz-Institute of Freshwater Ecology and Inland Fisheries, Müggelseedamm 310, 12587 Berlin, Germany 2German Federal Institute for Risk Assessment, Max-Dohrn-Str. 8-10, 10589 Berlin, Germany *Corresponding author: Federal Institute for Risk Assessment, Max-Dohrn-Str. 8-10, 10589 Berlin, Germany. Tel: +49 (0)30184120. Email: [email protected] .............................................................................................................................................................. Almost all life on earth has adapted to natural cycles of light and dark by evolving circadian and circannual rhythms to syn- chronize behavioural and physiological processes with the environment. Artificial light at night (ALAN) is suspected to interfere with these rhythms. In this study we examined the influence of ALAN on nocturnal melatonin and sex steroid blood concentrations and mRNA expression of gonadotropins in the pituitary of European perch (Perca fluviatilis) and roach (Rutilus rutilus). In a rural experimental setting, fish were held in net cages in drainage channels experiencing either additional ALAN of ~15 lx at the water surface or natural light conditions at half-moon. No differences in melatonin concen- trations between ALAN and natural conditions were detected. However, blood concentration of sex steroids (17β-estradiol; 11-ketotestosterone) as well as mRNA expression of gonadotropins (luteinizing hormone, follicle stimulating hormone) was reduced in both fish species. We conclude that ALAN can disturb biological rhythms in fish in urban waters. However, impacts on melatonin rhythm might have been blurred by individual differences, sampling methods and moonlight.

Orientador: Prof. Dr. André Andrian Padial Co-orientador: Luís Fernando Fávaro Curitiba 2017 3 RESUMO Atherinella brasiliensis, também conhecida como peixe-rei, é uma espécie de peixe neotropical pertencente à família Atherinopsidae. A espécie é de pequeno porte, oblonga, com uma faixa longitudinal prateada que, por assim, também a confere o nome de “Brazilian Silverside”. A referida espécie se distribui da Venezuela ao Rio Grande do Sul e é uma espécie abundante ao longo da costa brasileira, é bioindicadora, com grande importância para sustentar as redes tróficas, além de ser fonte de renda e alimento. Diante disso, faz-se necessário uma revisão sistemática da literatura sobre os atributos morfométricos e aspectos reprodutivos, e sua relação com o habitat. Há registros em diversos ambientes, como baías, estuários e águas salobras, vivendo em ambientes rasos e demonstrando uma alta capacidade de osmorregulação. A. brasiliensis apresenta características com tendência r-estrategista e possui hábito alimentar generalista e oportunista. A espécie é importante na manutenção do equilíbrio trófico e também em estudos de impacto em ambientes estuarino. A partir de revisão sistemática da literatura, 70 artigos foram pesquisados, em sua maioria realizados na região sul, dos quais 29 continham informações sobre atributos morfométricos e reprodutivos que foram tabelados e suas relações analisadas.

Samples were collected monthly between March 1992 and February 1993 in three freshwater coastal lakes. Standard length-total length (Ls-Lt) and weight-length (Wt-Lt) relationships studied showed interspecific differences in comparisons between juveniles and adults, males and females. Age was determined by scales. The three species presented a life-cycle duration of 4 to 5 years, with growth coefficients values (K) between 0.37 and 0.63, and asymptotic lengths between 211 and 257 mm. Some interspecific differences may be useful for dis- tinguishing between species (sexual and life-stage related patterns in Ls-Lt and Wt-Lt).

  • Comparación De Las Comunidades Parásitas De O
    Capítulo VI Comparación de las comunidades parásitas de O. bonariensis La riqueza específica, el número de especies centrales, la diversidad, la carga parasitaria y la predictibilidad fueron superiores en los pejerreyes post-larvales y juveniles y adultos de la laguna Salada Grande, excepto en el caso de la carga parasitaria de los individuos post-larvales que fue superior en la laguna Lacombe, lo cual se encuentra relacionado con el número de hospedadores examinados en cada laguna (91 en Lacombe y 34 en Salada Grande). Al analizar individualmente las infracomunidades, se puede observar que en la Salada Grande, el número medio y máximo de especies por infracomunidad es mayor que en la laguna Lacombe (Tabla Nº 58). Por otro lado, al comparar la prevalencia y la abundancia estacional de las metapoblaciones parásitas comunes a ambas lagunas, se advierte que C. macdonaghi, A. mordax y Eimeria sp. presentaron diferencias significativas en la mayoría de las estaciones del año, mientras que Contracaecum sp. presentó disparidad en la mitad de ellas (Tabla Nº 59). Esto indicaría que las metapoblaciones parásitas presentan una dinámica estacional diferente en los dos ambientes estudiados. Similitud entre las comunidades parásitas de O. bonariensis Los pejerreyes de ambas lagunas comparten seis especies parásitas. En la laguna Salada Grande se obtuvieron cuatro especies de digeneos que no se hallaron en la laguna Lacombe. El índice de similitud de Jaccard (Cj =0.60), indica que las comunidades parásitas de las lagunas Salada Grande y Lacombe tienen una similitud del 60%. Al comparar las comunidades parásitas de los hospedadores juveniles y adultos de ambas lagunas, se puede observar que la similitud es levemente inferior que globalmente (Cj =0.56), en tanto que la similitud entre los hospedadores post-larvales es mayor (Cj =0.80).

Age was determined by scales. The three species presented a life-cycle duration of 4 to 5 years, with growth coefficients values (K) between 0.37 and 0.63, and asymptotic lengths between 211 and 257 mm. Some interspecific differences may be useful for dis- tinguishing between species (sexual and life-stage related patterns in Ls-Lt and Wt-Lt).
