Fishing for silver carp and bighead carp under photovoltaic panels

Are silver carp outperforming bigheaded carp?

Silver carp numbers and biomass are increasing exponentially and they tend to become the dominant species of bigheaded carps in co-invaded habitats (Sass et al. 2010; Garvey et al. 2012 ). This may suggest that SV are outperforming BH, as indicated by their population growth.

Can silver carp be integrated with common carp?

The statistical results of the experiment also showed that the integration with silver carp improved not only the net production, growth rate, and feed efficiency of common carp, but also the total fish production and the integrated benefit index of the waters.

Is silver carp a filter-feeding fish?

1. Introduction Silver carp (Hypophthalmichthys molitrix) is one of the four major Chinese carps and a typical filter-feeding fish of the Cyprinidae. It is ubiquitously distributed in major waters of China and other Asian countries (Xie and Chen, 2001).

The silver carp is of the second-highest production yield among all the farmed fish species around the world and its production reached 4.79 million tons in 2018 (FAO, 2020).

Are bighead and silver carp hybrids nutritionally similar?

Early generation bighead and silver carp hybrid groups were intermediate to both parental lines, thereby, reducing their nutritional performance, and advanced generation bighead and silver carp groups were nutritionally more similar to their respective parental species.

What is the best ratio of silver carp to common carp?

Considering various factors, the best ratio of silver carp to common carp is 1:3 in the reservoir. It should be noted that due to environmental protection China has gradually banned the net cage farming of fed fish in multi-functional reservoirs.
