“…The result showed that the ovulation ratio was 100% in group 1 with a latency time of 9.5 h, followed by group 2 with 85.7% and group 3 with 71.4% and a latency time of 10 h. This study's findings indicate that using sperm at a dose of 2.0 ml/kg in combination with 5 mg of a 2.0 ml dose of CPE resulted in successful ovulation and a high rate of fertilisation in silver catfish, Rhamdia quelen (Ittzés et al, 2020). The administration of hormones in combination with the injection of sperm from many males can be used in breeding programs to minimise bottleneck effects, synchronise egg production, avoid inbreeding, and reduce mortality.…”

“…Furthermore, ovarian lavage is also preferred because it is a simple method for administering spawning hormone and eliminates injections for small species, such as spotted green pufferfish (Tetraodon nigroviridis) (Watson et al, 2009). Furthermore, the ovarian lavage approach is less time-dependent than the established in vitro fertilisation, and it could utilise sperm samples from chosen males depending on any factor to introduce a new generation (Ittzés et al, 2020).…”

Aquaculture has been the fastest-growing area of worldwide food production and is becoming a vital component of the global economy to feed the rising world population. Hence, directed toward continuing the current level of per head consumption, comprehensive aquaculture production needs to attain eighty million tonnes by 2050. However, some cultured marine fish species, such as salmonids, striped bass, and gilthead seabream, as well as freshwater fish, such as captive Mediterranean amberjack populations (Seriola dumerili) and Mekong River giant catfish (Pangasianodon gigas), exhibit reproductive dysfunction, especially in female brood stock when reared in captivity. Captive females face complications with unsynchronised ovulation, fail to undergo final oocyte maturation (FOM), and no longer spawn due to a lack of luteinising hormone (LH). Thus, artificial breeding has been widely used in aquaculture practices to increase cultured fish production. Farmer has extensively applied commercial hormones such as human chorionic gonadotropin (hCG), Ovaprim, Ovatide, and Ovaplant, through injection and implantation of hormones to stimulate breeding in many farmed fish species. However, artificial breeding is still in its development phase, and some methods are still unable to induce spawning in certain fish species. Different methods, doses, and delivery systems of artificial hormones could improve the efficiency and effectiveness of artificial breeding. This paper discusses the current research on artificial breeding in various fish species as well as new approaches or techniques to be applied in the area to regulate the reproductive process in captive fish for sustainable aquaculture.

“…Since the discovery of the sequence of the mammalian peptide GnRH 124 and other similar peptides in fishes 125 such as -s-GnRH (salmon), various synthetic analogues with higher biological activity have been designed by replacing the amino acids in positions 5-6 and 9-10, 90 and these analogues; have been used to induce spawning of C. macropomum, 126 P. mesopotamicus 24 and Rhamda quelen. 127 However, GnRHa has been more commonly used in combination with dopamine antagonists that enhance the stimulatory effect of GnRH analogues, such as the preparations Ovaprim ® (20 μg ml -1 sGnRH + 10 mg ml -1 domperidome). Ovaprim ® at 10 μg kg -1 body weight of s-GnRH, has been successfully used to stimulate spawning of Pseudoplatystoma punctifer 128 and P. fasciatum, 129 R. quelen 130 and Prochilodus lineatus.…”

Aquaculture offers solutions to meet the growing global demand for fish, and reports from the UN‐FAO indicate that aquaculture production in Latin America (LA) has grown at rates above the world average in recent years. One of the major constraints in the diversification of LA aquaculture is the control of reproduction in several popular native fish species for which difficulties in captive propagation have not yet been sufficiently overcome. This article reviews the use of hormone treatments to promote reproduction in females of these native fish species. LA has played a key role in the history of development of hormone administration, including the first hormonally induced spawning. That contribution is included in a historical overview of the discovery of the major hormones used in fish culture. The review provides a summary of difficulties to propagate females of various native fishes and the effects of administering hormones to enhance reproduction. Induced spawning of certain freshwater species was mainly achieved with pituitary extracts or human chorionic gonadotropin (hCG), although gonadotropin‐releasing hormone analogues (GnRHa) treatments are being researched, and successful studies suggest that low doses may be more effective. Research on new and emerging aquaculture species has applied both gonadotropins (Gths) and GnRHa‐based treatments, and GnRHa treatments have shown potential for marine species. However, native marine species new to aquaculture have also been conditioned to spawn spontaneously without hormones. Finally, we proposed future lines of research to examine reproductive strategies and GnRHa‐based hormone treatments to improve reproductive control for economically important fish species of LA.

“…In Brazil’s southern region, there is a great interest in the commercial cultivation of Rhamdia quelen ( Battisti et al, 2020 ). Its broad geographical distribution and low temperatures tolerance make it attractive to cultivate in different parts of the Neotropical region, especially in Southern Brazil, Uruguay and Argentina ( Salhia et al ., 2008 ; Gomes et al, 2000 ; Ittzéz et al ., 2020 ). Thus, it is necessary to identify the species to avoid unintentional crossings ( Scaranto et al, 2018 ).…”

Cryptic diversity and diversification processes in three cis-Andean Rhamdia species (Siluriformes: Heptapteridae) revealed by DNA barcoding

The wide distribution of the Neotropical freshwater catfish Rhamdia offers an excellent opportunity to investigate the historical processes responsible for modeling South America's hydrogeological structure. We used sequences from cis-Andean and Mesoamerican Rhamdia species to reconstruct and estimate divergence times among cis-Andean lineages, correlating the results with known geological events. Species delimitation methods based on distance (DNA barcoding and BIN) and coalescence (GMYC) approaches identified nine well-supported lineages from the cis-Andean region from sequences available in the BOLD dataset. The cis-Andean Rhamdia lineages diversification process began in Eocene and represented the split between cis-Andean and Mesoamerican clades. The cis-Andean clade contains two principal groups: Northwest clade (MOTUs from Amazon, Essequibo, Paraguay, and Itapecuru basins) and Southeast clade (Eastern Brazilian shield basins (Paraná, Uruguay, Iguaçu, and São Francisco) plus eastern coastal basins). The diversification of the cis-Andean Rhamdia lineages results from vicariance and geodispersion events, which played a key role in the current intricate distribution pattern of the Rhamdia lineages. The wide geographical distribution and large size of the specimens make it attractive to cultivate in different countries of the Neotropical region. The lineages delimitation minimizes identification mistakes, unintentional crossings by aquaculture, and reduces natural stocks contamination.
