Paperback. Condizione: new. Paperback.

Paperback. Condizione: new. Paperback. L'acquariofilia e uno degli hobby piu diffusi nei paesi sviluppati e sta guadagnando popolarita anche in molti paesi in via di sviluppo. Il crescente interesse per i pesci d'acquario ha portato a un aumento costante del commercio di questi animali a livello globale. Uno dei principali ostacoli alla produzione economica di avannotti di pesci ornamentali di alta qualita e l'imprevedibilita della qualita delle uova. Oltre all'attenta selezione dei riproduttori, la qualita delle uova dipende principalmente dalla gestione e dall'alimentazione dei riproduttori stessi. L'alimentazione ha un effetto diretto sulla maturazione, sulla produzione di uova e sulla sopravvivenza degli avannotti. Per ovviare a tutte queste variabili, nella presente ricerca e stata formulata una dieta artificiale in base alle esigenze nutrizionali dei riproduttori di Pterophyllum scalare, parallelamente all'allevamento dei pesci.

Paperback. Condizione: new. Paperback. Die Zierfischhaltung ist eines der beliebtesten Hobbys in den Industrielaendern und gewinnt auch in vielen Entwicklungslaendern zunehmend an Beliebtheit. Das wachsende Interesse an Aquarienfischen hat weltweit zu einem stetigen Anstieg des Handels mit Aquarienfischen gefuehrt. Ein wesentliches Hindernis fuer die wirtschaftliche Produktion hochwertiger Zierfischbrut ist die Unvorhersehbarkeit der Eierqualitaet. Neben der sorgfaeltigen Auswahl der Zuchtfische haengt die Eierqualitaet in erster Linie vom Management der Zuchtbestaende und von deren Ernaehrung ab. Die Ernaehrung hat direkten Einfluss auf die Reifung, die Eierproduktion und das UEberleben der Brut. Um all diese Variablen zu umgehen, wurde im Rahmen der vorliegenden Untersuchung ein kuenstliches Futter entsprechend den Ernaehrungsbeduerfnissen von Pterophyllum scalare-Zuchtfischen entwickelt und gleichzeitig die Aufzucht der Fische durchgefuehrt.
