2021-12-20·1. Introduction. With the rapid increase of the world population, the demand for high-quality proteins greatly drives the development of aquaculture (Degefu et al., 2011).Global production of aquaculture increased from 41.7 Mt in 2000–120.1 Mt in 2019 ().Fish is one of the most traded food commodities and the main source of valuable …
2017-12-5·Although feed intake may also increase when improving feed efficiency in crucian carp of this study (r = 0.590 between FCE and ADFI, p < 0.001), the correlation level was inferior to growth.
2016-11-1·1. Introduction. There is great diversity between fish species concerning the kinds of molecules that are detected by taste buds, that are accepted and stimulate foraging, the natural food choice being probably important (e.g. Carr, 1982, Mackie, 1982, Jones, 1992, Kasumyan and Døving, 2003).Feed that does not taste right, does not taste …
2021-4-30·Improvement in fish feed conversion efficiency (FCE) is beneficial for sustaining global food fish supplies. Here, we show that a set of polymorphisms at locus of the corticotropin releasing hormone receptor 2 (crhr2), which is involved in hypothalamus-pituitary-interrenal (HPI) axis signaling, is associated with improved FCE in farmed …
2017-11-15·Crucian carp can also be stocked as a secondary species; in this case the stocking density is normally 1500-1800 fish/ha of 7-10 cm fish. Finally, the fish can reach 300 g and crucian carp production can achieve 450-900 kg/ha, which usually accounts for 5-10 percent of total production.
2018-7-19·Whatever the reasons, crucians are delightful fish to catch. So, without further ado, let’s take a look at how to catch crucian carp, along details of current efforts to preserve this unique species. 1. Is it a “true cru”? Before any talk of tackle and tactics, our first step is to track down one or two genuine crucian carp fisheries.
Identification of Carassius Carassius Taxonomy. The crucian is a cyprinid, like most of our coarse fish. Its scientific name is Carassius carassius, linking it to Carassius auratus, the goldfish, with which it readily inter-breeds.It also forms hybrids with the common carp, Cyprinus carpio. So, there are two Carassius species in our waters. Abroad, there is a …

2022-9-29·The crucian carp (Carassius carassius) is a cyprinid fish with its natural distribution in Europe and the western part of Asia. Due to its hardiness and unique ability to survive winter anoxia, it has been translocated to small lakes and ponds, and in Northern Europe since medieval times has been used as a food source. Crucian carp was the only …
