“…Based on follicles diameter distribution of M. boesemani rainbowfish there is more than one modus explained that the M. boesemani rainbowfish classified as multiple spawner. The same indication seen on ovary of M. arfakensis rainbowfish (MANANGKALAGI, 2009) which is stated that this rainbowfish classified as multiple spawner based on follicles diameter distribution where there is more than one modus. The similar finding also found in research conducted by Siby (2009) on ovary of Glossolepis incisus rainbowfish which is stated that several modus in follicles diameter distribution indicates multiple spawner.…”

“…The type of spawning also can be indicated based on follicles diameter distribution with several modus. Multiple spawner fishes secreted mature follicles more than once ovulation and also can be indicates that there is more than one group of mature follicles (MANANGKALAGI, 2009;SIBY, 2009). Based on follicles diameter distribution of M. boesemani rainbowfish there is more than one modus explained that the M. boesemani rainbowfish classified as multiple spawner.…”

“…Ovari maturation stages consist of OMS I (immature), OMS II (early development), OMS III (developing virgin and resting adult), OMS IV (late developing) and OMS V (gravid) based on ovary development and maturity of rainbowfish. Oocytes development consist of oogonia, perinuclear oocyte, cortical alveoli oocyte, vitelogenic oocyte, mature oocyte, and atresia based on description of Siby (2009), Manangkalagi (2009), Yon, Aytekin and Yuce (2008), . The proportion of the oocytes were counted for determined oocytes cell type distribution in each maturation stages.…”

“…Ovari maturation stages of Boesemani rainbowfish M. boesemani were described according to ovary development and maturity of rainbowfish which is consist of OMS I (immature), OMS II (early development), OMS III (developing virgin and resting adult), OMS IV (late developing) and OMS V (gravid). Ovarian histology of rainbowfish M. boesemani ovary based on the presence of yolk, nucleus, and nucleoli (SIBY, 2009;MANANGKALAGI, 2009;YON, AYTEKIN and YUCE, 2008. The first ovary maturation stage of M. boesemani rainbowfish reffered OMS I (Figure 1a). Ovary at OMS I marked with small size of previtelogenic oocytes and contained small amounts of nucleoli.…”

Introduction: This research aim is to described ovary maturation stages histologically related with oocytes development in ovary of boesemani rainbowfish M. boesemani from North Ayamaru district, Maybrat Regency, West Papua. Materials and Methods: A histologycal analysis of ovari maturation stage (OMS) of the Boesemani rainbowfish Melanotaenia boesemani performed on 93 ovaries. Fresh ovaries were fixed in 10% Neutral Buffered Formalin (NBF) and embedded in paraffin. Section of about 5-6 pm thickness were cut and stained with Hematoxylin eosin (HE). Results: Histologycal analysis of rainbowfish M. boesemani ovaries based on oocyte development consist of 8 oocyte types not included atresia follicle i.e oogonia, early perinuclear oocyte, late perinuclear oocyte, cortical alveoli oocyte, early vitelogenic oocyte, mid-vitelogenic oocyte, late vitelogenic oocyte, and mature oocyte. The chorion and follicle layers begins to form at OMS II, keeps growing at OMS III, and was apparent at OMS IV. The chorion and follicle layers at OMS V ovaries were disintegrated. Conclusion: Based on ovary histology, oocyte proportion, and follicles diameter distribution can be concluded that the rainbowish M. boesemani classiied as multiple spawner.

Riparian vegetation has an important role in maintaining water stability, one of which is the river. This study aims to describe the structure of riparian vegetation so that its implications can be seen for the conditions of rainbow arfak habitat on the Nimbai River. The study was conducted in three forest types, namely primary riparia forest, secondary riparia forest and open riparia forest. Sample collection of riparian vegetation was carried out by purposive sampling using sample plots. Plots measuring 2 m x 2 m are used to sample seedling and understorey growth, plots measuring 5 m x 5 m for growth at the stake level, while plots measuring 10 m x 10 m and 20 m x 20 m, for growth of pole and tree levels respectively. The identification results obtained a total of 35 species of understorey and 51 tree-level plants in all three types of riparian forests. Based on the analysis of vegetation structure, it is known that the condition of primary riparia forest and secondary riparian forest still relatively supports the life of arfak rainbow fish compared to open riparian forest. Higher tree level density associated with canopy cover which has implications for the temperature of the water to be colder and less fluctuating, input larger litter into the food chain in the river, and hold suspended particles into the river. Also, the function of riparian vegetation in spawning activities, substrate attaching eggs and nursery habitat for arfak rainbow fish larvae. The results of this study indicate the importance of riparian vegetation structure on the condition of rainbow arfak fish habitat. An understanding of the structure of vegetation is also a basic information for efforts to rehabilitate this endemic fish habitat to maintain the existence of a natural population.

Pterygoplichthys pardalis is a type of fish that is widely used by people around the Ciliwung River as raw material for food production. In addition, P. pardalis has not been cultivated. The process of fish farming requires a number of information and data on fish such as reproductive biology. Therefore, the research aimed is calculating the reproductive aspects of P. pardalis. The result for this research can be applied for fish farmers to start P. pardalis bredding process. The methods used are P. pardalis sampling, measurement of total length and weight, dissection of samples, calculation of gonad weight and liver weight, egg diameter, fecundity, calculation of gonad maturity stages (GMS), gonadosomatic index (GSI), hepatosomatic index (HSI), relationship of fecundity with gonad weight, relationship of egg diameter with gonad weight, relationship of fecundity with total weight, and length-weight relationship. GMS calculation results showed most male fish found in GMS I, while females were most found in GMS IV. The smallest GSI value was found in GMS I and the highest was in GMS IV both in male and female and the fecundity was 737-3820 eggs with egg diameters ranging from 1.571 mm-4.310 mm. Both male and female P. pardalis have negative allometric growth patterns
