    Development of integrated multipurpose animal recording systems 2016
    Also available in:

    Animal identification and recording serves multiple purposes in a country’s livestock sector. It is a prerequisite to establish and operate any genetic improvement programme. It also contributes to animal traceability and disease control, as well as to deterring stock theft. Traceability of animals and their products helps to ensure the safety and quality of animal products, and contributes to enhance market access and to generate larger incomes for producers and other players in the value chain . Animal recording systems are therefore not just an information system but a powerful tool for livestock development and for contributing to global demands for food security and poverty alleviation. To make animal recording systems effective, they must be supported by appropriate public and private policies, and a legal and institutional framework. These multiple uses of animal identification and recording highlight the need to adopt multipurpose systems that integrates animal identification an d registration, animal traceability, animal health information and performance recording. The FAO guidelines for development of integrated multipurpose animal recording systems have been prepared with the objective of helping countries to design and implement such systems and to maximize the chances that they will be sustained. These guidelines put performance recording in a more general context, and hence to complement rather than replace the previous FAO guidelines. These guidelines focus prim arily upon the process rather than the methods and the technology (e.g. details of the equipment and measurements), since the latter is sufficiently covered by other guidelines. Where necessary, the guidelines are formulated to suit low or medium input production environments.

    Description of two new species of sandlances, genus Bleekeria (Perciformes, Ammodytidae) from the Andaman Sea (northeastern Indian Ocean) 2021

    Two new species of Bleekeria Günther, 1862 are described from specimens collected in the Andaman Sea off the coast of Myanmar during bottom surveys conducted by the R/V Dr Fridtjof Nansen in 2015 and 2018. They are distinguished from each other and from congeners by a combination of morphological and meristic characters as well as fin coloration and genetic variance. Bleekeria albicauda sp. nov. has pelvic fins, 40–41 dorsal-fin rays, 54–55 total vertebrae, no teeth in jaws, 4 scale rows between dorsal-fin origin and lateral line, a single row of about 10 scales on mid-upper part of opercle, scales on central part of body clearly shorter than their height, caudal fin with white upper and lower lobes when fresh (unique within the genus). Bleekeria nigrilinea sp. nov. has no pelvic fins, 37–39 dorsal-fin rays, 49–50 total vertebrae, 2½ scale rows between dorsal-fin origin and lateral line (the smallest count within the genus with B. estuaria of Mozambique brackish water), 5–6 scales on mid-upper part of opercle arranged in a single row, scales on central part of body clearly longer than their height, upper and lower margins of caudal fin black when fresh (unique within the genus). The COI gene sequences of the two new species showed clear genetic divergence (pairwise K2P, >10 %) from Bleekeria estuaria Randall & Ida, 2014 and Bleekeria mitsukurii (Jordan & Evermann, 1902). A key to the species of Bleekeria is provided.
