Abstract



Bu çalışmada yapay
fotoperiyot uygulamasının 3+ yaşlı Dağ alabalığı (Salmo macrostigma) damızlıklarının üreme dönemi ve kuluçka başarısı
üzerindeki etkileri araştırılmıştır. Çalışmada fotoperiyot grubunu oluşturan
balıklar, 01
Şubat – 31 Mayıs 2013 tarihleri arasında sürekli uzun gün (18A:6K), 01
Hazirandan itibaren ise sürekli kısa gün (8A:16K) uygulamasına tabi
tutulmuştur. Kontrol grubunu oluşturan balıklar ise doğal aydınlık-karanlık
döngüsüne tabi tutulmuştur. Yapay fotoperiyot döngüsüne tabi tutulan erkek
damızlıklardan 15 Ağustos’tan itibaren sperma/süt gözlenirken, dişi balıklardan
ilk yumurta alımı 30 Ağustos’ta gerçekleşmiş ve 13 Eylül’de pik noktaya
ulaşmıştır. Fotoperiyod uygulaması ile mevsim dışı yumurta veren dişi
balıkların ortalama mutlak yumurta verimi 1242,48±382,55 adet/balık,
oransal yumurta verimi 1148,76±336,91 adet/kg, ortalama yumurta çapı ise
4,14±0,19 mm olarak bulunmuştur. Sağılan mevsim dışı yumurtaların ortalama
döllenme, gözlenme ve açılma oranı sırasıyla %56,77,  %20,81 ve %11,95 olarak saptanmıştır.
Fotoperiyot grubundaki dişi damızlıkların ortalama yumurta verimi ile mevsim
dışı elde edilen yumurtaların kuluçka başarısı (yumurta çapı, döllenme,
gözlenme ve açılma oranları) kontrol grubundakine göre daha düşük olmasına
rağmen genel olarak elde edilen sonuçlar yapay sürekli uzun ve kısa gün
uygulaması ile Salmo macrostigma’nın üreme mevsimin düzenlenmesini ve
mevsim dışı yumurta sağımının mümkün olduğunu göstermektedir.

Abstract



The effects of artificial photoperiod manipulation on spawning time and
hatchery success of 3+ old mountain trout (Salmo
macrostigma) broodstock were investigated. 
Broodstock fish in the photoperiod group were exposed to constant long
days (18L:6D), from February
1st  until May 31st, 2013 and
then to constant short days (8L:16D)
starting from June 1st, 2013. The fish in the control group
were exposed to natural light-dark regimes. Out-of-season milt was observed in males starting from
August 15th. Out-of-season spawning of females started in August 30th and
reached its peak level in September 13th. Mean values of absolute fecundity,
relative fecundity, and egg size were found to be 1242.48±382.55
eggs/fish, 1148.76±336.91 eggs/kg and 4.14±0.19 mm respectively. Mean
fertilization, eyeing, and hatching rates of out-of-season eggs were determined
as 54.76%, 20.79%, and 12.56% respectively. Regardless of the fact that the
mean fecundity of females in the photoperiod group and hatching success (egg
diameter, fertilization, eyeing, and hatching rates) of out-of-season eggs were
lower than those in the control group, the overall results demonstrate that
that regulating spawning time and out-of-season spawning of mountain trout by
the use of artificial photoperiod is possible.
