Reproduction and Nursing of Cirrhinus Molitorella in a Small Fish Farm In
Reproduction and nursing of Cirrhinus molitorella in a small fi sh farm in Luang Prabang Province, Lao PDR Tick NUANTHAVONG1* and La VILAYPHONE2 1Aquaculture of Indigenous Mekong Fish Species Component, MRC Fisheries Programme, 2Ban Xepeing Village, Luang Prabang Disctrict, Luang Prabang Province ABSTRACT The propagation of C. molitorella has started in 1991 and this species is now considered domesticated. The Lao Sub-component of AIMS has supported several farmers in Luang Prabang in Northern Laos in producing C. molitorella through technical assistance and materials support. The present study describes the current technique for conditioning the fi sh breeders in ponds and for the reproduction, as practised in a small family fi sh farm in the Luang Prabang province. The study was carried out in 2005. The broodstock of C. molitorella consisted in 35 fi shes weighing 300-350. Fish were stocked in ponds (800 m2) together with four other species of fi sh breeders. Fish breeders were fed with rice brand and local vegetables as main feeds and additional compound feed (30 % proteins) during the breeding season from May to August. The natural reproduction of C. microlepis was induced with a single injection of LHRH associated with domperidone. Spawning occurred six hours after the injection; the fecundity per female was about 31,000 eggs. Incubation of the fl oating eggs lasted 16-17 hours at 26-28°C; the hatching rate was 90 %. Trials of nursing were carried out successively in tanks (5-7 days) and in two kinds of hapas held in the pond for fi ve weeks. The survival rate after nursing was about 20 %. -

Note that some fields concerning aspects of Part 3, the Ecological Character Description of the RIS (tinted in purple), are not expected to be completed as part of a standard RIS, but are included for completeness so as to provide the requested consistency between the RIS and the format of a ‘full’ Ecological Character Description, as adopted in Resolution X.15 (2008). If a Contracting Party does have information available that is relevant to these fields (for example from a national format Ecological Character Description) it may, if it wishes to, include information in these additional fields. 1 - Summary Summary Van Long Wetland Nature Reserve is a wetland comprised of rivers and a shallow lake with large amounts of submerged vegetation. The wetland area is centred on a block of limestone karst that rises abruptly from the flat coastal plain of the northern Vietnam. It is located within the Gia Vien district of Ninh Binh Province. The wetland is one of the rarest intact lowland inland wetlands remaining in the Red River Delta, Vietnam. -

The Allotetraploid Origin and Asymmetrical Genome Evolution of the Common Carp Cyprinus Carpio

Here, we generate three chromosome-level reference genomes of C. carpio and compare to related diploid Cyprinid genomes. We identify a Barbinae lineage as potential diploid pro- genitor of C. carpio and then divide the allotetraploid genome into two subgenomes marked by a distinct genome similarity to the diploid progenitor. We estimate that the two diploid progenitors diverged around 23 Mya and merged around 12.4 Mya based on the divergence rates of homoeologous genes and transposable elements in two subgenomes. No extensive gene losses are observed in either subgenome. Instead, we find gene expression bias across surveyed tissues such that subgenome B is more dominant in homoeologous expression. CG methylation in promoter regions may play an important role in altering gene expression in allotetraploid C. carpio. 1 Key Laboratory of Aquatic Genomics, Ministry of Agriculture, Chinese Academy of Fishery Sciences, Fengtai, Beijing 100141, China. 2 State Key Laboratory of Marine Environmental Science, College of Ocean and Earth Sciences, Xiamen University, Xiamen 361102, China. -

Also, some kind of plants are the main food source for aquatic animals. Plants are able to stabilize sediments, improve water clarity and add diversity to the shallow areas of lakes. On the other hand, overgrown plants can become a nuisance by hindering human uses of water and threaten the structure and function of diverse native aquatic ecosystems. This chapter aims to make analysis of using of grass carp to control aquatic vegetation. In this concept, origin and distribution, biological features, reproduction, feeding behaviour and effects of grass carp on aquatic plants, water body and sediments are also discussed. Keywords: aquatic plants, grass carp, biological control, ecology, habitat 1. Introduction Aquatic plants are important elements in water reservoirs. They play a fundamental role in energy and carbon storage at the bases of food pyramids. In addition, they act as protection and reproduction refuges for many organisms, and its submerged parts allow the develop- ment of periphyton communities [1]. Unfortunately, as beneficial as they are, aquatic plants can easily overpopulate and become a nuisance to the landowner. -

Host-Specific Dactylogyrus Parasites Revealing New Insights on The
Šimková et al. Parasites & Vectors (2017) 10:589 DOI 10.1186/s13071-017-2521-x RESEARCH Open Access Host-specific Dactylogyrus parasites revealing new insights on the historical biogeography of Northwest African and Iberian cyprinid fish Andrea Šimková1*, Michal Benovics1, Imane Rahmouni2 and Jasna Vukić3 Abstract Background: Host specificity in parasites represents the extent to which a parasite’s distribution is limited to certain host species. Considering host-specific parasites of primarily freshwater fish (such as gill monogeneans), their biogeographical distribution is essentially influenced by both evolutionary and ecological processes. Due to the limited capacity for historical dispersion in freshwater fish, their specific coevolving parasites may, through historical host-parasite associations, at least partially reveal the historical biogeographical routes (or historical contacts) of host species. We used Dactylogyrus spp., parasites specific to cyprinid fish, to infer potential historical contacts between Northwest African and European and Asian cyprinid faunas. Using phylogenetic reconstruction, we investigated the origin(s) of host-specific Dactylogyrus spp. parasitizing Northwest African and Iberian cyprinid species. Results: In accordance with hypotheses on the historical biogeography of two cyprinid lineages in Northwest Africa, Barbini (Luciobarbus) and Torini (Carasobarbus), we demonstrated the multiple origins of Northwest African Dactylogyrus. Dactylogyrus spp. of Carasobarbus spp. originated from Asian cyprinids, while Dactylogyrus spp. of Luciobarbus spp. originated from European cyprinids. This indicates the historical Northern route of Dactylogyrus spp. dispersion to Northwest African Luciobarbus species rather than the Southern route, which is currently widely accepted for Luciobarbus. In addition, both Northwest African cyprinid lineages were also colonized by Dactylogyrus marocanus closely related to Dactylogyrus spp.
