Induced diploid meiogynogenesis in the African clariid catfish Heterobranchus longifilis (Valenciennes, 1840) (Pisces: Clariidae)

Diploid meiotic gynogenesis was induced in African catfish, Heterobranchus longifilis by injection of 0.5ml/kg ovaprim on the breeders, followed by application of UV light irradiation on the spermatozoa and temperature shocking of activated eggs. Diploidy was restored by shocking haploid activated eggs at 5 degree C for 40 minutes. The normal control spermatozoa did not receive any UV irradiation nor temperature shock, while the haploid control spermatozoa were irradiated, but did not receive cold shock. The percentage hatchability in the treated group was 25%, while in the control it was 53%. Less than 15 fingerlings had morphological aberrations. After two weeks of indoor rearing, the survival percentage of the treated group was 45% in the control experiment. Cytogenetic analysis of chromosomes revealed 25 chromosomes in the haploid embryo and 50 chromosomes each in diploid gynogenesis and normal diploid control

Embryogenesis of Heterobranchus longifilis (Curvier and Valenciennes, 1840)

Studies on development of H. longifilis (Curvier and Valenciennes, 1840) were conducted at a temperature of 25EC ( 1Ec) in aquaria tanks continuous development were monitored with the use of wild Heerbrugy photomacroscope and length of yolk and larva were monitored using Stereo Olympus microscope with ocular micrometer. The division into animal and vegetal poles was observed 22 minutes after activation. The first cleavage occurred 65 minutes after activation while the second division which was perpendicular to the first line of division occurred 74 minutes after activation. This was quickly followed by the third and fourth cleavage at 80th and 82nd minutes after activation respectively. Morular stage was reached at 4 hours 20 minutes with formation of optic bud at 14 hours 35 minutes. (DBO) Developing embryo hatched after 27 hours of activation at a mean length of 6.63 and mean yolk length of 2.17. Yolk size decrease at an average rate of 38.5 % till the 5th day of total absorption. Growth of larvae proceeded faster in tail-anus region than in anus-snout portion of the body. The rate of yolk absorption and larva development (survival) as monitored in this work gives important information in Research and development programme for H. longifilis larva - an important aspect of Research development and implementation of appropriate technologies in small scale fisheries

Inmigración, familia y empleo. Estrategias familiares en los inicios de la industrialización, Pamplona (1840-1930)

Dónde, con quién y de qué vivir son cuestiones clave a la hora de explicar las estrategias familiares, y también los ejes de este libro. Tras explicitar sus premisas teóricas y plantear las líneas generales en la evolución de la ciudad, Iruñea-Pamplona, el libro se estructura en tres capítulos que analizan cada una de las estas preguntas. Por un lado, el autor constata la importancia de la inmigración y analiza las lógicas familiares que guían estos movimientos, así como su influencia en la realidad lingüística urbana. En segundo lugar estudia las diferencias sociales en la formación de los hogares, apreciando un fortalecimiento de la familia obrera en los inicios de la industrialización. Por último se centra en la participación de los diferentes miembros de la familia en el mercado laboral, prestando especial atención al empleo femenino, los valores de género subyacentes y la feminización de la pobreza. Se trata de una investigación sobre estrategias familiares, que también pretende reflexionar sobre el papel de los valores familiares en el mantenimiento del orden social.

Toxicité des sulfures dissous chez le poisson-chat africain, Heterobranchus longifilis (Valenciennes, 1840)

Biological tests were carried out using static bioassay systems to determine the median lethal concentration of total sulfide (H2S, HS, S2) for African catfish (Heterobranchus longifilis, Valenciennes, 1840) at fry and juvenile stages.
