Abstract:
Growth performance of Oreochromis mossambicus (Cichlidae) (Peters, 1852) as well as phyto- and zooplankton production were estimated in water filled cisterns receiving Mixed Fertilizer (MF; Single super phosphate and Urea in 1:1 ratio), Single super phosphate (SP) and Vermicompost (VC) as direct application fertilizer. Significant differences (P<0.001) were observed in the diversity and abundance of plankton in response to fertilization with MF, SP and VC. The different fertilizer and manure used can be graded in the following descending order: VC, MF and SP. The least concentration was accounted in control sets. The highest production of fish was obtained in vats treated with VC (4,000.00 kg.ha-1 90 day-1) followed by MF (3,100.00 kg.ha-1 90 day-1), SP (2030.00 kg.ha-1 90 day-1) and the lowest in control (CO) sets (390.00 kg.ha-1 90 day-1). The highest yield of fish in vats applied with VC is attributed to its highest manorial value. |

Balık Çiftçiliği Havuzlarında Vermikompostun Doğal Gübre Olarak Doğrudan Kullanılması
|
| Oreochromis mossambicus’un (Cichlidae) büyüme performansı (Peters, 1852), aynı şekilde fitoplankton ve zooplankton üretimi; doğrudan uygulanan suni gübre olarak Kompoze Gübre (MF; 1:1 oranında Single Sürperfosfat ve Üre), Single Süperfosfat (SP) ve Vermikompost (VC) alan, su ile doldurulmuş tanklardan tahmin edilmiştir. MF, SP ve VC ile gübrelemeye cevap olarak plankton çeşitliliği ve bolluğu bakımından anlamlı farklılar gözlendi (P<0,001). Kullanılan suni ve doğal gübre şu azalan sırayla derecelendirilebilir: VC, MF ve SP. En az konsantrasyon, kontrol setlerinde görüldü. En yüksek balık üretimi; VC (4.000,00 kg.ha-1 90 gün-1) verilen tankta ve daha sonra MF (3.100,00 kg.ha-1 90 gün-1) ve SP (2.030,00 kg.ha-1 90 gün-1) verilen tanklarda, ve en düşük balık üretimi ise kontrol (CO) setlerinde (390,00 kg.ha-1 90 gün-1) elde edildi. Verimin; VC verilen tanklarda en yüksek olması, VC’nin “manorial” değerinin en yüksek olmasına atfedilmiştir. |
