The inhibitory effects and positive contributions of live foods on protease activities of meagre, argyrosomus regius (Asso 1801), larvae in vitro assay
(MDPI AG, 2019)
The determination of exogenous enzyme contributions in live food is important in larval feeding. This study investigated the potential inhibitory effects and contributions of live foods used from 3 to 32 days after hatching ...
Could the growth of Litopenaeus vannamei be compensated by long-term cyclic feed deprivation and following refeeding?
(Taylor and Francis Inc., 2019)
The effects of long-term cyclic feed deprivation and refeeding on compensatory growth and body composition of Litopenaeus vannamei were assessed for five different feeding protocols (i.e., 0, 1, 2, 4, 7 days fasting/days ...
Effect of immersion treatment of soybean isoflavones extract on sex reversal in the Rainbow Trout (Oncorhynchus mykiss, Walbaum, 1792)
(Universitatea din Oradea, 2019)
This study explores the possible utilization of soybean isoflavones extract as potent alternatives for induction of sex reversal in the rainbow trout (Oncorhynchus mykiss, Walbaum, 1792) with immersion treatment. Different ...
Artificial sex reversal of white grouper (Epinephelus aeneus) utilizing aromatase inhibitor (Fadrozole)
(Wiley, 2019)
The white grouper is a desirable aquaculture species that adapts to captivity, grows well and commands a high market price. However, little is known about reproductive biology or control of sex reversal of this protogynous ...
Effect of biofloc technology on growth of speckled shrimp, Metapenaeus monoceros (Fabricus) in different feeding regimes
(Wiley, 2019)
The effects of biofloc technology (BFT) were tested on growth performance, water quality, haemolymph parameters and hepatopancreas histology with and without BFT for the speckled shrimp. In this study, eight different ...
Effect of different cryoprotectants (glycerol, methanol and dimethyl sulfoxide) on post-thaw quality, viability, fertilization ability and DNA damage of cryopreserved nile tilapia (oreochromis niloticus) spermatozoa
(Cryo Letters, 2019)
BACKGROUND: Cryopreservation of sperm from different fish species requires different protocols. Therefore, it is necessary to perform studies to establish reliable procedures for each species. OBJECTIVE: Experiments were ...
Atresia and apoptosis in pre- and postovulatory follicles of sharptooth catfish (clarias gariepinus, Burchell, 1822)
(University of Punjab (new Campus), 2019)
Ovarian follicular atresia and postovulatory regression in mammals is mediated by apoptosis, which is a natural occurring cause of cellular death. However, its function in fish is largely unknown. In order to discuss the ...
Effects of Soybean Oil Supplementation on the Growth and Survival Performance of Red Claw Crayfish Cherax Quadricarinatus in Culture Condition
(Parlar Scientific Publications (P S P), 2019)
The current study investigated the effects of soybean oil on the growth and survival of red claw crayfish (Cherax quadricarinatus) under culture conditions. An experiment consisting of four dietary soybean oil concentrations ...
The Characterization and Activity of Protease Enzyme on Different Days of Tadpoles [Pelophylax ridibundus (Pallas, 1771)]
(Istanbul University Press, Faculty of Aquatic Sciences, 2019)
In this study, protease enzyme activity of Pelophylax ridibundus (Pallas, 1771) tadpoles was determined during the larval period starting from 25 Gosner stage (1960). When the P ridibundus tadpoles reached the 25 Gosner ...
Effects of Biofloc Technology (BFT) on Growth of Speckled Shrimp (Metapenaeus monoceros)
(Ankara University, 2019)
The effects of biofloc technology (BFT) on growth and hepatopancreas histology of speckled shrimp Metapenaeus monoceros (initial weight: 8.32 +/- 0.69 g) were investigated for 30 days. The trial was conducted in fiberglass ...
