Moisture, protein, and amino acid contents of three freshwater zooplankton used as feed for aquacultured larvae and postlarvae

Abstract

As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.

Spatial microheterogeneity and selective microbial consumption of dissolved free amino acids in an oligomesotrophic lake

“…Single algal species differ in their AA release patterns (Sarmento et al 2013; Hornˇák et al 2016), and so might algal (e.g., diatom) colonies. The dominant AAs in various zooplankton species (Ovie and Ovie 2006) or in particular tissues of single species (Schmidt et al 2004) may greatly deviate from those in the typical DFAA pool. Of course, both explanations are not mutually exclusive.…”

“…DFAA composition would also be expected to more closely match to that of DCAAs. On the other hand, some AAs may be disproportionally released from specific particle types (Ovie and Ovie 2006; Sarmento et al 2013), or free‐living bacteria (i.e., not associated with the point sources) may preferably consume particular AAs during periods when overall DFAA consumption equals or exceeds release (Salcher et al 2013; Hornˇák and Pernthaler 2019). These AAs would then be over‐ or underrepresented in release “hotspots” and “background” areas, respectively.…”

Effects of Caulerpa lentillifera added into culture media on the growth and nutritional values of Phronima pacifica, a natural fish-feed crustacean

“…44.16%) that used organic waste fermented with probiotic bacteria. According to Ovie and Ovie (2006), Valverde et al (2013) and Herawati et al (2015), lysine forms the structural framework of vitamin B1, has antiviral effects, facilitates the absorption of calcium, enhances appetite, and facilitates the production of carnitine that enhances the conversion of fatty acids into energy. The high lysine contents in P. pacifica used as natural feed could increase growth.…”

Nitrogen retention, nutrient digestibility and growth efficiency of Nile tilapia ( Oreochromis niloticus ) fed dietary lysine and reared in fertilized ponds

“…Filter-feeding Nile tilapia may indirectly support phytoplankton production by grazing on zooplankton and reducing its abundance (Leoni et al, 2018;Vasconcelos et al, 2018). Ovie and Ovie (2006) and Rasdi et al (2020) reported that the lysine content of laboratory-cultured Rotifera and Cladocera (Branchiopoda) could range between 86 and 107 g kg −1 CP, making lysine their most abundant essential amino acid. This possible high content of lysine in zooplankton in our experiment might in part explain why the correlation was stronger for the LowL diet than for the BalL diet.…”
