Sažetak
We studied the mutual benefit of geese and fish raising in a common habitat, a fish pond. Birds living in or very near water in aquatic or wetland habitats, live in a symbiotic relationship with the fish, whereby a cycle is closed when the bird droppings enhance the development of zooplankton and phytoplankton, which provides the basis for fish nutrition. Also, in the floor keeping of geese feed is lost in bedding material, but in this system, feed in the pond falls into the water and serves as fish feed. The floor keeping of animals burdens the manufacturer with a large production of bedding material, resulting in higher costs of the technological process for manure removal and disinfection. In addition to cost, bedding material and disinfection pollute the environment; such pollution is completely negligible in the technological process in this study. This paper describes the technology of raising geese on fish ponds. The results showed that gosling mortality was negligible, only 1.5% in the initial warm breeding phase. The final weight of geese was on average 5.37 kg of body mass. Upon reception,
the one-year old carp weighed 100 g and during the production cycle, their mass increased to 250 g without additional feeding.
