Different indices related to the fish and to the sperm parameters are considered, including gonadosomatic index (GSI), hepatosomatic index (HSI), condition factor (K), sperm ejaculate volume and concentration, and sperm motility duration. Male and female GSI peak is observed in April-May. HSI expresses an inverse pattern compared to GSI in both sexes, and K index changes inversely compared to GSI. The lowest values of K index are observed during the spawning season revealing corporal reserve mobilization in the mating effort. The first sexual maturity of 50% of the fish is observed at 18 and 21 cm TL in the males and females, respectively. Maximum ejaculate volume (6500 μL on average) is observed in May and June. Positive correla- tions are observed between sperm ejaculate volume and fish length and weight.

Biological parameters of Luciobarbus callensis populates Beni-Haroun dam, north- eastern Algeria. Biodiversitas 21: 5691-5697. Fish age and growth data mainly assist many ichthyologists to understand the life history features of species and populations Growth is a major process of fish biology, and considered as one of the key processes of length- structured models of fishes. Thus, the present study was devoted to studying growth of an autochthonous species (Luciobarbus callensis), populating the dam of Beni-Haroun (Mila city, northeast of Algeria), and is known for its socio-economic value and aquaculture interest. The study was conducted on a sample of 257 fish individuals during the period 2015-2016. The age of L. callensis was determined by using the scalimetry method, providing easier sampling and reading procedures, and also high precision. Fish sexes were identified via the observation of gonads, by naked eye based on gonad shape and color, where the number of females was higher (165) than males (92).The obtained results revealed a maximum longevity of seven years of L.

The workshop took place in the beau- tiful surroundings of the High Tatras, Slovakia in the Congress Centre Academia, Stará Lesná near Tatranská Lomnica on September 9 – 13th. This special event was hosted by the Slovak Society for Parasitology, the Institute of Parasitology of the Slovak Academy of Sciences, Košice, Slovakia, and the Czech University of Life Sciences Prague, Czech Republic. It consisted of nearly three dozen lectures presented by distinguished acanthocephalan specialists who came from 13 countries and fi ve continents. Vibrant discussions and creating new plans for future collaborations were accompa- nied by local mountain touring that offered the venue richly endowed with nature, deep forests and beautiful mountains. The contributions were addressed to resolve current systematic, taxonomic, biological, behavioural, ecological, and related topics. Presented results showed the most recent progressive developments comparable with all the other parasitic worm groups.

Gante Zoological Institute, University of Basel, Basel Switzerland 1. Introduction The Mediterranean Basin is one of the 25 most biodiverse regions on Earth. It is considered a biodiversity hotspot for its high numbers of endemic vascular plants, birds, mammals, reptiles, and amphibians, sometimes restricted to small distribution areas (Médail & Quézel, 1999; Mittermeier et al., 1998; Myers et al., 2000). The Mediterranean has had a long and complex geomorphologic history, being a relic of the Mesozoic Tethys Ocean. The Tethys had disappeared by the end of the Eocene (34 Ma) due to the collision of the Indian and Asian plates (Rögl, 1999). The orogenic movements raised new mountain ranges in the Taurides, the Hellenides, the Dinarides and finally the Alps by the Middle/early Late Miocene (Hsü et al., 1977). This orogeny separated the borning Mediterranean and a central/eastern European inland sea – the Paratethys Sea (Hsü et al., 1977; Rögl, 1999). Landbridge connections and seaway passages between the Mediterranean and Paratethys, and between them and the Indian and Atlantic oceans, were then intermittent throughout the Miocene until the final opening of the Strait of Gibraltar ending the Messinian Salinity Crisis (Agustí et al., 2006; Hsü et al., 1977; Krijgsman et al., 1999; Rögl, 1999).

Marine Biological Research Institute, Sagar Island, Sundarban, West Bengal-743373, India Abstract Amblypharyngodon mola and Pethia ticto are small indigenous fish species belonging to family cyprinidae and considered as primary freshwater fish widely distributed in Indian subcontinent including Sundarban region. The 96-h median lethal salinity (MLS96 h) level of these fish was found out by exposing to saline water (0-10 ppt) in direct transfer method. The 96-h median lethal salinity for A. mola was found to be 6.20 ppt with 95% confidence intervals of 4.38-7.09 ppt where as for P. ticto it was 6.12 with 95% confidence intervals of 3.67-7.07 ppt. The Probit showed that at 6.12-6.20 ppt, 50% of the both test species shows sensitivity to salinity that leads to mortality.

Parasites may be particularly insidious as they are often introduced unintentionally, simultaneously with their hosts, and later transferred to species in the new location.
