Comparative efficacy of different inducing agents on breeding performance of a near threatened cyprinid Osteobrama belangeri in captivity

Annually twice induced spawnings provide multiple benefits: Experimental evidence from an Indian major carp ( Catla catla , Hamilton 1822)

“…These findings corroborate the results of other studies (Kestemont, Rinchard, Damoiseau, & Tans, 2001;Maddams & McCormick, 2012), while they are not consistent with some other evidences (Chattopadhyay, 2017;Heins et al, 2004). The possible reasons for these non-significant results could be using almost the equal-sized females (Beldade et al, 2012;Benton, St Clair, & Plaistow, 2008), applying same induced breeding technique (Das et al, 2016;Szabó, Urbányi, Müller, Szabó, & Horváth, 2019), providing less stress (Contreras-Sánchez et al, 1998;Mylonas, Fostier, & Zanuy, 2010) and feeding with optimum diet (Izquierdo, Fernández-Palacios, & Tacon, 2001;Rahman, Rahman, Hossain, Yeasmin, & Asif, 2016), etc.…”

Spawning performance, serum sex steroids, and ovarian histology in wild-caught Levantine scraper, Capoeta damascina (Valenciennes, 1842) treated with various doses of sGnRHa + domperidone

“…It has been shown that the latency period varies greatly among species and depends on both intrinsic (Wendling et al, 2000) and environmental parameters (Yaron, 1995), as well as the type of hormone or dose (Wang et al, 2009;Das et al, 2016). Recorded latency periods in our study were different across the hormonal gradient, with shorter latency periods when sGnRHa + domperidone was administered in higher dosages.…”

The Genetic Research Methods and its Role in Aquaculture on Indonesia

“…Injections could also with a solution of the pituitary gland of goldfish. Way, catch the mature female parent gonad; prepare 2 kg of goldfish size 0.5 kg for each female parent; cut the goldfish vertically right behind the gills tutu; cut the head horizontally just below the eye; dispose of parts of the brain; take hypopisa glands; enter the pituitary gland into the crushing glass and crush it; input 1 cc aquabides and mix well; suction hypopisa solution; injections into the female parent's back; input the parent that has been injected into another tub and leave for 10 -12 hours [151][152][153][154].…”

“…One person holding the head and massaging and another holding a plastic tail and bowl. Keep the sperm out of the water [151,153]. Egg discharge was done after 10-12 hours after injection, but 9 hours before checking.…”

“…Egg discharge was done after 10-12 hours after injection, but 9 hours before checking. Procedure to remove eggs are prepare 3 pieces of plastic basin, a bottle of sodium chloride, a chicken feather, a duster and a tissue; catch the parent with the net screw; dry the mother body with a small towel or a towel; wrap the parent with a towel and leave the egg hole open; grasp the head by one person and grasp the tail by the other; massage the abdomen toward the hole by the head holder; eggs in a plastic basin; mix the sperm solution into the egg; mix well with chicken feathers; add sodium chloride and mix thoroughly; dispose of the liquid tCelcius degree lean the eggs from the blood; eggs ready [153,155].…”
