“…The distribution of oil globules has been used as an indicator of egg quality in European perch (Zarski et al, 2011b) and brown trout, Salmo truttafario (Mansour et al, 2007). There was no relationship between oil globule distribution in the oocyte and the quality of the eggs especially with respect to reproductive performance of the domesticated rainbow trout (Ciereszko et al, 2009).…”

“…The eggs of silver perch were classified based on the oil globule fragmentation following the category stated by Zarski et al (2011b) with minor modifications. However, only three out of four categories were observed in this research.…”

“…It is widely accepted that egg quality affects both egg and larvae viability which in turn is reflected in several characteristics of larvae including physical deformity, growth rate, mortality rate, and size variability (Zarski et al, 2011b). The difference in individual performance can lead to high cannibalism which, at the end, will directly determine production effectiveness (Rowland, 2009).…”

“…The difference in individual performance can lead to high cannibalism which, at the end, will directly determine production effectiveness (Rowland, 2009). In silver perch, egg quality is commonly evaluated based on the viability of larvae after hatching (Rowland, 1984;2009) while earlier determination of egg viability could be a beneficial tool to eliminate low quality eggs leaving incubation of only good eggs quality as in Eurasian perch, Perca fluviatilis (Zarski et al, 2011b).…”

“…Mastery of the techniques of fish reproduction is an important step as it is directly related to aquaculture productivity (Zarski et al, 2011a;Zarski et al, 2011b). Silver perch hatchery has been based on the hypophysation technique to spawn the broodstocks and pond-based larval rearing techniques (Rowland, 1984;2009).…”

The experiments investigated the reproductive performance of the domesticated broodstock of the silver perch and the relationship between various degrees of oil globule fragmentation and egg quality. Six years old of second generation broodstock (n=3) were evaluated based on the fecundity, fertilisation rate, hatching rate, the degree of oil fragmentation of egg, and the quality of embryos and larvae produced. The fragmentation were grouped into three categories: un-fragmented (cat-1), moderately fragmented (cat-2), and highly fragmented (cat-3). The results showed that the broodstock had a relatively high fecundity (132,400 ± 7,22), fertilization rate (94.27 ± 1.28%), and hatching rates (87.94 ± 1.23%). The survival rate of larvae at 12 days post hatching (dph) in cat-1 (71.3 ± 0.9%) was higher than cat-2 (66.7 ± 0.9%) whereas cat-2 was higher than cat-3 (61.3 ± 0.3%). The eggs was dominated by cat-1 (78.11 ± 2.44%) which was significantly higher than cat-2 (21.26 ± 2.45%) and cat-3 ones (0.40 ± 0.21%). The survival rate of embryo at 20 hours post spawning (hps) and hatching rate of cat-1 (95.33 ± 0.00% and 93.33 ± 0.00%) and cat-2 (90.00 ± 0.00% and 85.00 ± 0.00%) were significantly higher than cat-3 (72.33 ± 1.76% and 60.33 ± 0.00%). The total length (TL) of the larvae of cat-1 and cat-2 (8.44 ± 0.21 mm and 8.35 ± 0.23 mm respectively) were significantly higher than larvae of cat-3 (7.09 ± 0.14 mm). No significant difference was found in the larval deformities among any categories. In conclusion, the reproductive performance of six year-old broodstock silver perch showing acceptable performance and egg categorisation based on oil globule fragmentation can be used as a useful tool to indicate eggs quality of silver perch.
