Antalya Bölgesindeki Süs Balığı Üreten İşletmelerin Yapısal ve Teknik Analizi: II. Teknik Özellik ve Pazarlama Durumları

Özet

Ornamental fish farms have emerged in Antalya, Turkey, during the last 10 years as an alternative to other aquaculture
and agriculture activities due to their high market values. The present study aimed to determine the technical and economical
aspects of the operations using data collected with interviews with 9 farms in Antalya. The data indicated goldfish production
is dominant in the region. This species is followed by guppies, cichlids and koi. Farmers use commercially available rainbow
trout diets in general whereas few can also use their own feeds. Majority of the farms (8 out of 9) use live food during various
periods. For instance, goldfish are also fed tubifex worms during reproduction period whereas larval live bearing species are
fed artemia and daphnia. There were 200-2000 The number of female broodstock of gold fish, live-bearers, cichlide and koi
in the farms ranged between 250-2000, 250-6000, 1000-1400 and 4-40, respectively. The number of male broodstocks of the
species was as much as twice that of females. Survival rate of juvenile fish was 70%. Famers pointed out that 44% of fish
loss occurred in individuals weighing less than 0.5 g and the most widespread disease was the columnaris. Marketing weight
is generally 1.5-5 g with a price of around 40-50 TL. Wholesale marketing share is 55.56%. It is concluded that old farms and
those which receives consultancy service are more successful. There is a tendency in the farms to increase species diversity
and production amount.
