چکیده
This study was aimed to examine the different natural feeds on maturnity of freshwater crayfish. The conducted November 20th - January 21th 2021 in UPTD BBI Lukup Badak, Takengon, Aceh Tengah. Test fish used is seed cherax quadricarinatus measuring 52-75 g. Methods this Completely Randomized Design (CRD) with 4 treatments and 3 replications. were P1 (Tubifex), P2 (505 tubifex, 255 carrots, 25% sweet potatoes), P3 (50% bean sprouts, P4 papaya, potatoes). Seeds put a container maintenance 42 liters water volume density 1 tails per container. Frequency feeding times day at 08.00 am, 16.00 pm 20.00 pm. results showed that teratments had very significant effect absolute weight gonad maturity indexs (IKG).Keywords: Absolute weight, Cherax quadricarinatus, Gonad, Natural feed.

Direct Age Determination of a Subtropical Freshwater Crayfish (Redclaw, Cherax quadricarinatus) Using Ossicular Growth Marks
Recent studies have reported that crustacean age determination is possible. We applied a direct ageing method (i.e. transverse cross sectioning of gastric ossicles) to a subtropical freshwater crayfish (Cherax quadricarinatus) sourced from an aquaculture population. Growth mark periodicity and the potential for chronological depositions were investigated by staining C. quadricarinatus with calc...
متن کاملCircadian oscillations of RPCH gene expression in the eyestalk of the crayfish Cherax quadricarinatus.
The RPCH and beta-actin cDNAs from the crayfish Cherax quadricarinatus were amplified, cloned and sequenced. The primary structure sequences of these cDNAs were compared to other members of the AKH/RPCH family. Fluctuations in the amount of the C. quadricarinatus RPCH and beta-actin mRNAs, as cDNAs, were quantified every 3h by RT-PCR. Single cosinor analysis supports the notion of beta-actin an...
متن کاملDistribution and establishment of the alien Australian redclaw crayfish, Cherax quadricarinatus, in South Africa and Swaziland
BACKGROUND The Australian redclaw crayfish (Cherax quadricarinatus, von Martens), is native to Australasia, but has been widely translocated around the world due to aquaculture and aquarium trade. Mostly as a result of escape from aquaculture facilities, this species has established extralimital populations in Australia and alien populations in Europe, Asia, Central America and Africa. In South...
متن کاملThe eyestalk-androgenic gland-testis endocrine axis in the crayfish Cherax quadricarinatus.
In decapod crustaceans, a number of neurohormones regulating a variety of physiological processes, including reproduction, are to be found in the X-organ-sinus gland complex of the eyestalk. Bilateral eyestalk ablation was thus performed in mature males of the Australian red claw crayfish Cherax quadricarinatus with the aim of studying the role of eyestalk-borne hormones on spermatogenic activi...
متن کاملStimulation of molt by RNA interference of the molt-inhibiting hormone in the crayfish Cherax quadricarinatus.
In crustaceans, molting is known to be under the control of neuropeptide hormones synthesized and secreted from the eyestalk ganglia. While the role of molt-inhibiting hormone (MIH) in regulating molting has been described in several species using classical methods, an in vivo specific MIH targeted manipulation has not been described yet. In the present study, an MIH cDNA was isolated and seque...
