The purpose of this study was to identify and morphologically characterize the hemocyte cell types of freshwater crayfish, Cherax cainii. In addition to morphological observations using a light microscope (LM) and electron transmission microscope (TEM), a flow cytometer (FCM) is also used. Three main types of haemocyte of C. cainii were identified by LM, TEM, and FCM. Determination of haemocyte by LM based on the number, size of cytoplasmic granules and the ratio of N:C. These cells are Hyaline (HC), Small Granule (SGC), and Large Granule (LGC) cells. Three types of haemocyte were also observed by TEM based on cell and nucleus size, granule diameter, number of cytoplasmic granules per cell and N:C. Haemocyte population was successfully detected with FCM based on forward scatter (FSC) signals, versus side scattering signals/side scatter (SSC), with plot data via scatter parameter gating. Three cluster formations were observed, which were temporarily classified as SGC, LGC, and HC regions. Morphometric analysis was performed with TEM on C. cainii haemocyte to measure various cellular features. Some morphological features vary between types of haemocyte and are also affected by temperature. Total hemocyte count (THC) and differential hemocyte count (DHC) are calculated using FCM. THC increases with higher temperatures, from 1,9 x 106 /ml at 20 Â°C to 4.9 x 106 /ml at 30 Â°C. Â The most abundant hemocyte at all temperatures is HC, followed by SGC and LGC.

Oodev hormone application has been applied to stimulate gonadal maturity so that fish fry could be available outside the spawning season. This research aimed to study the effect of Oodev hormone on the gonadal maturity of asian redtail catfish Hemibagrus nemurus (Valenciennes, 1840). This research method used a completely randomized design (CRD) with 4 doses treatments, i.e 0, 0,25, 0,50, 1,00 ml/kg. A total of 8 fish were used as replications for each treatment. The parameters measured were the gonado somatic index (GSI) and egg diameter. The results showed that the effect of Oodev hormone on GSI and egg diameter was significantly different (P<0.05). A higher Oodev hormone dose caused an increase of GSI and egg diameter size. The recommended Oodev dose for application is 1 ml/kg.

The development of catfish culture affects increasing waste in the waters. Aquaculture waste containing high nutrients has the potential to damage the cultivation environment. The Biofloc system in catfish farming can break down NH3 waste into flocks that can be consumed directly by fish. This study aims to analyze the growth and survival rate of catfish in biofloc systems with different C:N ratios. The research design used was a completely randomized design (CRD) with four treatments and three replications. Siamese catfish seeds were maintained in an aquarium container size 40 x 30 x 30 cm for 40 days with treatment media A (maintenance without biofloc), treatment B C:N ratio 15, treatment C C:N ratio 20, and treatment D C:N ratio 25. The results showed that the biofloc system with different C:N ratios had significant effect on the weight growth, daily growth rate, and feed convertion ratio of catfish. The best treatment for growth and viability of catfish is C:N ratio 25.
