<p class="MsoNormal" style="text-align: justify;"> </p><p>Lionhead strain goldfish (<em>Carassius auratus</em>) inheritance produce many variations in phenotype qualitative traits of their offspring that is not common with the parents. Lionhead is an ornamental freshwater fish, they do not have a dorsal fin, but it is a beauty finfish, is popular to the people and have a high economic value. Of the 846 offspring of lionhead is produced in this experiment, and 57,7% of them have dorsal fin (42,3% normal), 13,1% of them have anal fin which did not similar with their parents, 58,6% caudal fin of them did not have similar to their parents. It might be caused by incompletely segregation in meiosis and many gen responsible to certain phenotype trait. Another abnormalities such as no anal fin, blindness, stumped and no pigmen in their gill lamella also occurred.</p> <p>Key words: Inheritance, fin, phenotype, abnormality</p> <p> </p> <p>ABSTRAK</p> <p>Ikan maskoki strain lionhead menghasilkan keturunan dengan fenotip yang sangat bervariasi dan berbeda dengan induknya. Ikan ini merupakan ikan hias air tawar yang tidak memiliki sirip punggung namun tetap memiliki keindahan, sehingga menjadi begitu populer di masyarakat dan memiliki nilai ekonomi yang tinggi. Sebanyak 846 keturunan (anakan) telah dihasilkan dalam percobaan ini, dan sebanyak 57,7% dari populasi tersebut memiliki sirip punggung (berarti 42,3% merupakan keturunan normal), 13,1% memiliki sirip dubur yang tidak mirip dengan induknya. Variasi keturunan ikan maskoki strain lionhead ini disebabkan oleh segregasi yang tidak sempurna dalam proses meiosis dan banyaknya gen yang terlibat dalam pembentukan penotip tertentu. Abnormalitas lainnya juga terjadi pada keturunan ikan maskoki strain lionhead ini, seperti tidak adanya sirip dubur, mata buta, tubuh pendek dan tidak adanya pigmen pada lemela insang</p> Kata kunci: Keturunan, sirip, fenotip, abnormalitas <br /><p> </p>

SummaryA preliminary characterization of a fibrinolytic inhibitor released by human umbilical vein endothelial cells in primary culture is reported. This molecule of Mr comprised between 2 × 105 and 106 and of μ2 mobility precipitates at 43% ammonium sulphate saturation and is totally adsorbed on Concanavalin A Sepharose 4 B. A possible relationship with a macroglobulins is discussed.

In this paper, we investigate the hydrodynamics of swimmers with three caudal fins: a round one corresponding to snakehead fish ( Channidae), an indented one corresponding to saithe ( Pollachius virens), and a lunate one corresponding to tuna ( Thunnus thynnus). A direct numerical simulation (DNS) approach with a self-propelled fish model was adopted. The simulation results show that the caudal fin transitions from a pushing/suction combined propulsive mechanism to a suction-dominated propulsive mechanism with increasing aspect ratio ( AR). Interestingly, different from a previous finding that suction-based propulsion leads to high efficiency in animal swimming, this study shows that the utilization of suction-based propulsion by a high- AR caudal fin reduces swimming efficiency. Therefore, the suction-based propulsive mechanism does not necessarily lead to high efficiency, while other factors might play a role. Further analysis shows that the large lateral momentum transferred to the flow due to the high depth of the high- AR caudal fin leads to the lowest efficiency despite the most significant suction.
