Growth and Feed Utilization by Golden Grey Mullet (Liza aurata) in a Coastal Lagoon Ecosystem, Fed Compound Feeds with Varying Protein Levels

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.

Comparison of mudcrab-based brackishwater polyculture systems with different finfish species combinations in Sundarban, India

“…It is reported that in 5 month culture lesser mullets attained a lower growth rate, 0.28 to 0.35 g DWG and 0.40 to 0.48% per day SGR compared with fast growing M. cephalus (Karapanagiotidis et al, 2004). However, in the present study L. parsia and L. tade recorded better growth performance (Table 3) compared with earlier observation (Biswas, Ananda Raja, et al, 2012;James, 1996;Shofiquzzoha et al, 2001).…”

“…Moreover, the residues of macrobenthos, fish or molluscan meal fed by mudcrabs also might have served as food for bottom detritus feeder grey mullet compared with plankton feeding milkfish. It is reported that in 5 month culture lesser mullets attained a lower growth rate, 0.28 to 0.35 g DWG and 0.40 to 0.48% per day SGR compared with fast growing M. cephalus (Karapanagiotidis et al., ). However, in the present study L. parsia and L. tade recorded better growth performance (Table ) compared with earlier observation (Biswas, Ananda Raja, et al., ; James, ; Shofiquzzoha et al., ).…”

Solid-State Hydrolysis (SSH) Improves the Nutritional Value of Plant Ingredients in the Diet of Mugil cephalus

“…Although the growth rates of M. cephalus were relatively low at the end of the 28-week feeding period, they were comparable to those reported in previous studies carried out with this and other similar species that evidence the slow growth rate of mugilids [29][30][31]. Legarda et al [32] reported an SGR of 0.56%/day for Mugil cephalus juveniles fed 1%bw daily in a biofloc system maintained at 28 ± 1 • C. Nengas et al [33] also recorded low SGR values (around 0.45%/day) in juveniles of Liza aurata fed once per day at 2% of their biomass at temperatures ranging from 12 to 26 • C.…”

“…In addition, it must be considered that the conditions in which the fish were maintained in this latter experiment, mainly a lower stocking density, could result in lower stress and a positive impact on feeding behaviour, resulting in better food utilization. Although there are few studies on the nutrition of mullets under field conditions, the study carried out by [33] on Liza aurata showed that growth and feed utilization of the fish was not significantly affected by variations in the dietary protein level. Such absence of a clear effect could be due to the possible complementary effect of natural food present in the water mass.…”
