Problems solved by technology

[0003] The purpose of the present invention is to solve the problems that the color, flavor and body shape of wild carp are far inferior to natural wild products under artificial breeding conditions, that is, the body color becomes dark, the body shape becomes fat, and the natural flavor is lost, and to provide a carp that can A compound feed that maintains the appearance and meat quality (character) of natural wild carp and can promote growth

Embodiment 2

[0018] Example 2 Feeding experiment

[0019] 1) The experimental fish were from the same batch of artificially hatched one-year-old wild carp fingerlings. Before the test, they were temporarily raised in an indoor aquarium, and 1,000 juvenile fish with robust and uniform size were selected; they were acclimated in the indoor aquarium, and the control group feed with a protein content of 35% was fed as the domesticated feed, and they were fed with full food and domesticated for 15 days. ;

[0020] 2) The feeding experiment lasted for 8 weeks; 6 treatment groups were designed according to the experimental design, with 3 repetitions in each group. Before the start of the experiment, feeding was stopped for 1 d, and then wild carp species (16.81±0.54g) with strong physique and uniform size were selected and stocked randomly. In the indoor aquarium, 30 fish are stocked in each box, and the daily feeding rate is 2.5-4.0% of the body weight, depending on the size of the fish, water ...

Embodiment 3

[0022] Example 3 Determination of growth and shape indicators

[0023] Raised for 8w, fasted for 24h before sampling, and weighed each replicate separately. Calculate the average growth rate and specific growth rate (SGR), etc. Another 9 fish were taken from each group (3 fish per repetition), and the water on the body surface of the fish was drained, and the white muscle above the lateral line and below the dorsal fin was taken to determine its nutritional content. The body weight and body length of 10 tails in each group were measured for each replicate, and the plumpness and viscera-to-body ratio were calculated. The specific calculation is as follows.

[0024] Average weight gain rate (%) = 100% × (W t -W 0 ) / W 0

[0025] Visceral body ratio (VI) = visceral mass (g) × 100 / fish body mass (g)

[0026] Fullness (CF) = (W / L 3 )×100

[0027] I(g) is the dry weight of ingested feed, W 0 (g) and W t (g) is the total weight of the fish at the beginning and end, t(d) is ...

Abstract

The invention discloses a compound feed for wild carps. Breeding experiments indicate that the compound feed for wild carps solves the problem that the artificially cultured wild carps are disadvantageous to natural wild products in terms of color, flavor and figure, namely the artificially cultured wild carps have dark body color, fat body figure and unnatural flavor, and that the compound feed for wild carps can retain the body figure and meat quality (property) of natural wild carps and promote the growth of the carps.

Description

technical field [0001] The invention relates to the field of aquaculture, specifically a compound feed of wild carp. Background technique [0002] Heilongjiang wild carp is an important economic indigenous fish species in the Heilongjiang River Basin. It is the original population of carp. At present, dozens of carp species cultivated in the world are differentiated and bred from wild carp. It has strong resistance to cold and other stress, especially the survival rate of overwintering is higher, and the protein content and amino acid content are higher than other carp (Yin Hongbin et al., 1999), providing excellent species resources for the Northeast aquaculture industry. In recent years, wild carp has become the main species of pond culture that northerners like to eat. Under natural conditions, due to good water space and abundant bait resources, its body color, body shape and meat quality have obvious advantages, but artificial culture has obvious advantages. Under cert...
