Abstract

The status of yellow trout fish resources in the northern waters of Manokwari until now has not been known with certainty regarding the distribution of size composition and growth patterns. This study was conducted to determine the frequency distribution in length and weight of yellow trout (S. leptolepis), the relationship between length and weight of yellow trout (S. leptolepis) and the growth pattern of the yellow trout in the northern waters of Manokwari. This research was carried out in a boat chart that made the landing of yellow trout fish at the Sanggeng Landing Fish Base (PPI) in Manokwari Regency and was carried out for 2 different months between May and July 2021. From the results of the analysis, it was found that the highest frequency distribution of S. leptolepis in May was in class range 16.24 – 16.82 cm with a total of 523 individuals, while in July the highest frequency of length was found in the class range 15.06 – 15.64 cm. The relationship between length and weight of yellow trout in the waters of North Manokwari has the equation W = 0.0533L2.4759, where length growth affects weight growth with R2 = 0.7436, meaning that the growth of yellow trevally in North Manokwari waters is allometric negative.

Abstract

The tuna waste in Manokwari has an economic potential that can be used as fish meal animal feed or fish feed. The aim of this study was to determine the chemical contents of tuna waste flour, examine of tuna waste meal, determine the feed test impact to the tilapia growth, analyze the impact of feed to water quality and analyze the feed manufacturing businesses. The study was conducted for six months (January to June 2015) at UD Madurasa. This study used, a completely randomized design with five treatments, there were feed A (control) and four test feeds formulated using tuna waste flour and bran (feed B, feed C, feed D and feed E). The feeds were tested using tilapia sized 5-8 cm and weighted 9-10 g in average (belo phase), then a 750 belos were used and allocated into 15 containers (50 belos / container). Feed was given twice a day in the morning (7:00 a.m. to 08:00) and afternoon (16:00 to 17:00) for six weeks. The feed amount was 5% of the body weight. The results show that tuna waste flour contain nutrients over the nutritional needs by tilapia. The tested feed has nutritional value better than feed A. Feed A has the highest efficiency and value of relative growth of 24.56% and 92.79%. Feed C has an efficiency of 22.83%, Feed E (20.37%), Feed B (19.30%) and Feed D (17.82%), also the growth of relative feed values of C (87.14%), Feed E (64.69%), Feed B (63.04%) and Feed D (55.53%). The variance analysis was not difference, however all feed gave same effect on tilapia growth. The tested feed did not pollute the water and categorized as 2nd and 3rd of water quality. It is assumed that this business is properly to be run with breakeven point will be achieved when sales reached to 8 kg (Rp 130,000.00) or at 4.5 months.

Abstract

In general, the presence of green open space as one element in the urban spatial is very weak and the potencial is reduced portion because they do not have a high economic value. One function of green open space is for micro-climate amelioration, making green open space as a lugs of the city for helping the formation of a cool and comfortable climate in the vicinity. This comfort is determined by the interdependence between the factors of air temperature, air humidity, light and wind movement. Vegetation can improve the quality of the local climate or reducing temperature named micro-climate amelioration function as well. This study aimed to evaluate and redesign the typology of green open space to create green resolution with conversion of carbon to compansate for changes in the landscape that occur as a result of ongoing development. The study was conducted in urban areas of West Papua Province with five cases were selected purposively. Refers to the Ministry of Public Work No. 5 of 2008 and some related references, the results of research (qualitative exploration research) showed that 3 of the 5 cases have not met the ideal typology of Green Open Spaces, while two other cases have met the ideal typology for ecological function, but remain in need of the final material. Redesigns of Green Open Spaces that has been generated from this study are expected to restore ecological functions with holding the ecologycal aspect as a priority matter to consider as well. Therefor those can be used by local goverments for planning repairs or improvements in the future.

Abstract

The purpose of this study was to determine the shape of the growth pattern of the relationship between carapace width and weight, growth parameters, and mortality and exploitation rate of mangrove crabs in the waters of Bintuni Bay Regency. This research was conducted in Teluk Bintuni Regency, West Papua Province. The sampling locations were spread in three locations, namely Bintuni, Manimeri and Babo. Mangrove crab samples obtained from fishing traps caught by fishermen in the waters of Bintuni Bay, identified gender (male or female), and measured carapace width and weight, then the measurement data were analyzed using the help of several data analysis formulas. Based on the results of the analysis, it is evident that the mangrove crab S. tranquebarica has a value of b = 3.6223 (male) with a positive allometric growth pattern and b = 2.8100 (female) with a negative allometric growth pattern, while the type of S. olivacea has a value of b = 2.8612 (male) and b = 2.1581 (female). The growth parameter values for male and female of S. olivacea were able to reach asymptotic carapace width (CW∞) = 20.90 cm, while males and females of S. tranquebarica (CW∞) = 18.90 cm and 19.21 cm, respectively. Natural mortality of S. tranquebarica in the waters of Bintuni Bay is estimated at 0.90 per year (male) and 1.31 per year (female), while S. olivacea is 1.02 per year (male) and 1.12 per year (female).

Abstract

Zooplankton play an important dual role in marine ecosystems as food webs connectors and sensitive indicators of water quality. This study examines the composition, abundance, and relationship of zooplankton communities with oceanographic parameters in the coral reef ecosystem of Manokwari Waters. Samples were collected from three observation stations: Kaki Island, Lemon Island, and Marampa Port, using a 25 μm plankton net. Morphological identification resulted in six classes of zooplankton, namely Hexanauplia, Gastropoda, Bivalve, Malacostraca, Branchiopoda, and Ostracoda, for a total of 23 species. The class Hexanauplia dominates in all locations, with the most abundant species being Undinula vulgaris (10 individuals), Calanus sinicus (7), and Eurytemora pacifica (6). Cluster analysis based on the Bray-Curtis similarity index with the Average Linkage method shows the similarity of zooplankton communities between Marampa Port and Lemon Island. Kaki Island forms a separate cluster, indicating differences in species composition spatially. The highest abundance was recorded in the Hexanauplia class with an abundance index of >2,500 cells/L in some species. Canonical Correspondence Analysis (CCA) revealed a positive correlation between DO and Bivalvia (+0.99), temperature with Gastropoda (+0.92), and salinity with Hexanauplia (+0.28). Environmental factors such as temperature, DO, pH, and depth have been shown to influence the spatial distribution and diversity of communities. These findings reinforce the dual role of zooplankton as a fundamental food source for benthic organisms such as the soft coral Sarcophyton sp. and as an effective bioindicator for monitoring the health of tropical coastal ecosystems.

Abstract

ABSTRACT: This study examines the microhabitat characteristics of the endemic rainbowfish Melanotaenia arfakensis in two major rivers of Tambrauw, Southwest Papua—Api River and Asiti River—focusing on the spatial dynamics of environmental parameters from upstream to downstream. Results indicate that water temperature, dissolved oxygen (DO), depth, current velocity, and river width show significant spatial trends and directly influence the survival of M. arfakensis. The upstream zones, characterized by lower temperatures (23–26°C), high DO levels (>7 mg/L), moderate current, and stable depth, are identified as optimal habitats and conservation priorities. In contrast, the midstream and downstream zones exhibit gradual habitat degradation, including temperature increases up to 29.1°C and decreased DO levels, approaching the physiological tolerance limits of the species. This decline in microhabitat quality correlates with riparian vegetation loss and anthropogenic pressures. Therefore, an effective in situ conservation strategy must be spatially explicit, adaptive, and participatory—emphasizing thermal refugia protection in the upstream zones, ecological restoration in the midstream, and integrated watershed management with community involvement in the downstream areas. Longitudinal connectivity and the integrity of the entire riverine ecosystem are essential for ensuring the long-term viability of this endemic species.
