Potentiality of new feed ingredients for aquaculture: A review

Abstract

The continuous demand for alternative protein sources for fish due to its short supply, high prices and competition with the human food. A review of unconventional feeds in fish nutrition was carried out to provide information on supplemental feed for effective Aquaculture. Non-conventional dietary energy and protein sources,especially from plant origin can be used to replace expensive protein sources. There is a continuous demand for alternative protein sources for fish due to short supply, cereals and oilseed mealsfor sustainable aquaculture production. The solid waste materials like distillers dried grain soluble, breweries waste, ghee residue and agricultural plant materials like jute, leucaena, moringa, cassava, rain tree and spirulina can find a place in formulation of aquafeed as one of the inexpensive feed ingredients. The non-conventional feed ingredients to be incorporated in fish feed up to recommended levels.

Evaluation of jute leaf as substitute of fish meal in the diet of mrigal (Cirrhinus cirrhosus) fingerlings

“…Importantly, feed cost in aquaculture accounts for 70 to 75% of the total cost of fish production (Gadzama and Ndudim, 2019;Katheline et al, 2019). Therefore, substitution of fishmeal (animal protein) with jute leaf powder could considerably lessen the feed cost in aquaculture without affecting fish growth (Singh et al, 2018).…”

Undesirable Microbial Growth from The Biodegradation Process of Nypa Palm Fronds Suplemented with Cellulolytic Bacteria Culture Isolated from Nypa Palm Worms (Namalycastis rhodochorde)

“…Budidaya cacing nipah secara intensif merupakan upaya konservasi dan memenuhi kebutuhan akan cacing nipah tanpa harus eksploitasi langsung di habitatnya. Dua komponen yang memengaruhi kesuksesan budidaya perikanan adalah nutrisi dan upaya pencegahan penyakit (Singh et al, 2018), komponen tersebut juga berlaku dalam proses budidaya cacing nipah. Hasil penelitian sebelumnya menunjukkan bahwa pertumbuhan larva cacing nipah skala laboratorium sangat lambat dan mudah terserang penyakit akibat parasit.…”

Comparative Effect of Varied Dietary Plant Protein Sources on Growth Performance of Rohu (<i>Labeo rohita Hamilton</i>)

“…In recent years due to escalating cost of groundnut oil cake and its increased demand not only for aquaculture industry but also for industries like poultry, a strong need has been felt to search for alternate sources for groundnut oil cake as a component of carp feed. Non-conventional feed resources has a lot of potentiality in farm-made aquafeed (Paul, 1999). In this paper an attempt has been made to explore the possibility of replacement of groundnut oil cake by mustard oil cake (a relatively low cost oil cake) and its level of inclusion to bring down the cost of diet without affecting the growth.…”
