for generating mixed fish and vegetables due to innovation and
more profound research. Suhardianto and Hartari (2023) research
found that biofloc catfish pond water can be used as a source
of nutrition in mustard growth. Other studies show by Wiyoto, W.,
Siskandar, R., Dewi, R. K., Lesmanawati, W., Mulya, M. A., & Ekasari, J.
(2023), Baskoro (2020) and Yustiningsih (2019).
It is achieved because biofloc technology is a cultivation
approach that leverages microbial group growth in water as a
source of nourishment for the organisms being cultivated. These
microbes are a group of bacteria, algae, and protozoa that form
brown or dark aggregates or flocs that contain critical elements
like protein, vitamins, and minerals required by fish and plants.
Fish and vegetables can thus grow in an integrated habitat in a
biofloc system. Fish use This microbial floc as a natural food source,
while the leftover feed and fish waste provide nutrients for growing
vegetable plants.
This system has several advantages, making it an attractive
alternative for meeting sustainable food needs and increasing
resource efficiency. Sustainable food needs: Combination farming
of fish and vegetables using biofloc can significantly contribute to
meeting sustainable food needs. In this system, fish and vegetable
plants grow together in a single container or pond, allowing for an
efficient nutrient cycle. Fish waste, such as ammonia produced by
fish waste, is a source of nutrition for vegetable crops. In contrast,
vegetable plants absorb water-soluble nutrients and reduce
excess ammonia and nitrate levels. In doing so, this system creates
a symbiotic relationship between fish and plants, in which they
mutually benefit from each other, resulting in sustainable food
production.
Natural resource efficiency: Combined fish and vegetable
aquaculture systems using biofloc can considerably improve
resource efficiency. One of the primary benefits of this approach is
that it requires less water than traditional growing methods. Biofloc
generated in ponds creates stable water conditions, allowing for
more efficient water utilization. Furthermore, nutrients from fish
waste are reused by vegetable plants after being digested by
