  • The Effect of Probiotic Addition in Commercial Feed to Growth and Survival Rate of Sangkuriang Catfishes (Clarias Gariepinus (Burchell, 1822))
    Available online at www.worldnewsnaturalsciences.com WNOFNS 21 (2018) 130-140 EISSN 2543-5426 The Effect of Probiotic Addition in Commercial Feed to Growth and Survival Rate of Sangkuriang Catfishes (Clarias gariepinus (Burchell, 1822)) Walim Lili, Rezky Hartanto*, Nia Kurniawati, Titin Herawati, B. S. Ibnu Bangkit Faculty of Fisheries and Marine Sciences Padjadjaran University, Bandung, Indonesia E-mail address: [email protected] ABSTRACT This study was conducted to determine the effect of probiotic addition in commercial feed to the growth and survival rate of Sangkuriang catfish (Clarias gariepinus). This research was conducted at the Ciparanje Experimental Pond Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Jatinangor, West Java. The method in used this research was Completely Randomized Design with four treatments and four replications. The treatment was the variances of probiotic addition which consisted of control (without probiotics), probiotic addition at as much as 0.5 grams / kg of feed, 1 gram / kg of feed and 1.5 grams / kg of feed. The parameters observed were specific growth rate (SGR), absolute biomass, survival rate (SR) and feed conversion ratio (FCR). Data were analyzed using Variant Analysis, at 95% confidence level, and continued with Duncan's Multiple Range Test. The results showed that the increase in the daily growth rate of Sangkuriang catfish was straight-line with the addition of probiotics. Furthermore, commercial probiotics with a dose of 1 gram / kg of feed resulted in specific growth rate of 4.22%, absolute weight of 11 grams, survival rate (SR) of 97.5% and FCR of 0.89. Keywords: probiotic, Sangkuriang catfish, feed conversion ratio, specific growth rate, survival rate, Clarias gariepinus 1.

C HRISteNSeN 2 Bishop Museum, 1525 Bernice Street, Honolulu, Hawaiʻi 96817-2704, USA; email: [email protected] the freshwater limpet heretofore known as Ferrissia sharpi (Sykes, 1900) was described as Ancylus sharpi from material collected on the Island of O‘ahu (Sykes 1900). the dis - cussion of the species by Hubendick (1967) added little new information, but by the end of the 20th century it had been reported from the islands of Kauaʻi and Hawaiʻi in addition to its type locality (Cowie et al. 1995; Cowie 1997). Recent surveys of Hawaiian stream fauna have recorded it from numerous localities on those islands and have added the islands of Moloka‘i and Maui to its known range within the state of Hawaiʻi (englund & Godwin 2002; englund & Preston 2002; Anthony et al . 2004; Brasher et al. 2004; Parham et al . 2008). Ferrissia sharpi has been a cryptogenic species in the Hawaiian fauna as its status as native or introduced has been unclear. Most recent authors have regarded its status as uncertain (Cowie et al. 1995; Cowie 1997, 1998; englund & Godwin 2002; englund & Preston 2002; Ziegler 2002; Anthony et al . 2004; Brasher et al. 2004), but Parham et al.

A report and an updated list with comments on the species of freshwater molluscs of Argentina which covers an area of 2 777 815 km2 is presented. Distributions of Gastropoda and Bivalvia families, endemic, exotic, invasive as well as entities of sanitary importance are also studied and recommendations on their conservation are provided. Molluscs related to the Del Plata Basin have been thoroughly studied in comparison to others areas of the country. This fauna exhibits relatively the biggest specific richness and keeps its affinity with the fauna of other regions of the basin in areas of Paraguay and Brasil. The 4 500 records of molluscs considered in this paper arise from the study of the collections of Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Buenos Aires; Museo de La Plata, La Plata and Fundación “Miguel Lillo”, Tucumán. These institutions keep very important collections of molluscs in southern South America. Field information has recently been obtained and localities cited by other authors are also included in the data base. Until today, 166 species have been described, 101 belonging to 10 families of Gastropoda and 65 to 7 of Bivalvia.

The relationship ol that species to Gundlnchin, or to other ancylicls, is obscure. Although otllcr frcsllrvater limpet-like snails have septa (e.g. Latin, Latiidae; A717,phigy~a,Planorbidae) they do not belong to the Ancylidae.

For the first time, we report on the widespread establishment of the globally invasive freshwater snail Physa acuta (Physidae) in Thailand and Laos, including decades old records that had previously been misidentified as Camptoceras jiraponi (Planorbidae). Occurrence of Physa acuta as hitchhikers among ornamental aquatic plants suggests that the ornamental trade was a likely introduction pathway of the species into Thailand. That a globally invasive species was able to spread unnoticed for such a long period of time highlights the need for countries like Thailand to focus research efforts on prevention and early detection of introduced species, in addition to increasing our understanding of native biodiversity.
