Beach forest is a unique type of ecosystem, a mixed group of littoral creepers, shrubs, and trees above the high tide level. In Sarangani Province, beach forest is not well studied even though it experienced various environmental threats due to the increase of coastal development and tourism. This study aimed to determine the composition and diversity of beach forest species in Barangay Kling, Kiamba, Sarangani Province and relate it to the whole coastal area of the municipality by producing a profile. Specifically, the study sought to determine the species composition of beach forest in the sampling areas; assess the beach forest diversity of at least three sampling areas in Barangay Kling. Using transect-quadrat method, species were identified through identification guides. Data analysis includes relative density, relative frequency, relative dominance, species diversity index and species importance value. Results of the assessment of species composition and community structure showed that a total of 39 beach forest species distributed among 23 families are present on the site, and another ten (10) species were observed outside of the transects. Milletia pinnata has the highest importance value with a rating of 79.04, followed by Terminalia catappa (65.54) and Barringtonia asiatica (44.04). The results show that the area has a huge potential for development into a beach forest park considering the diversity and maturity of the stand. In addition, management, protection, and rehabilitation of beach forest are also highly recommended to maximize their potential as climate change mitigators and their role in coastal protection.

Zamboanga is one of the significant fishing grounds in the Mindanao Region, but little is known about the conservation status of reef fishes, particularly in Dumanquillas Bay, Zamboanga. Thus, this study assessed the abundance, species diversity, and conservation status of reef fishes in the bay. The assessment was conducted within eight sampling stations from May 6 to May 16, 2014. Reef fishes were censused using a line-intercept method. Fourteen thousand fifty individuals and 140 fish species belonging to 30 families were recorded―dominated by the family Pomacentridae. The number of fish individuals was significantly more abundant in Triton Island Station than in other sampling stations, while Muyong Island has the most diverse reef fishes. Almost all species are classified as the least concern category, except for Plectropomus areolatus of Cabog Island, which is under the vulnerable (VU) category. The number of less-valued species was higher than the commercially high-valued species. Therefore, it may indicate the overharvest of the latter group of species. This comprehensive study on reef fishes in Dumangquillas Bay may serve as a reference for fisheries resource management planning or for drafting fisheries policies in the bay.

The research was conducted as many as 456 individuals of Planiliza abu, 500 individuals of P. klunzengeri and 600 individuals of P. subviridis. The purpose of this study was to analyze the frequency of fish lengths to determine stock expectations and analyze species population estimates using the VPA (Virtual Population Analysis) Method in the Shatt Al-Arab River from November 2015 to October 2016 using the FiSAT II program. The results showed that the growth patterns of the three species were negative allometric. The values of L∞ for the three species were 21.2, 27.0 and 29.3 cm, respectively. The rates of total mortality (Z), fishing (F), natural (M) and exploitation (E) for P. abu were 2.69, 1.09, 1.60 and 0.59, P. klunzengeri 2.49, 1.08, 1.41 and 0.57 and P. subviridis 1.51, 0.84, 0.68 and 0.45, respectively. The present exploitation rates (E) for all species are lower than the biological target reference points expressing a case of under-exploitation of the species. VPA showed that the maximum fishing mortality for the three species occurred in the mid-lengths, with maximum values at the length of 15 cm for P. abu and 17 cm for P. klunzengeri and P. subviridis. The mullets species catches have not met the criteria for good management (Lc50< Lm50), indicating that the fish may be vulnerable to capture before they mature. Accordingly, the present study proposes that the officials in fishery management can get more by yields through increasing the fishing activities on these species but must be matching the mesh sizes with the fishing recommendation to assure resource availability and sustainability.

This study aims to determine the Community's perception of the sustainability of resource use in Pangandaran District, Pangandaran Regency, West Java, 2022. The method used in this research is a survey method. The sampling technique used Accidental Sampling with a total of 50 respondents. Data collection use questionnaires and documentation techniques. Then the data was processed use the chi square method. The results showed that the sustainability of coastal resources in the Pangandaran District was classified as moderate, with a percentage of 48%. The factors that support the sustainable use of coastal resources include economic factors that have a calculated chi-square value of 15,089. Then, social factors have a calculated chi-square value that is 18, 163. Environmental factors also have a significant influence, namely by value. The calculated chi-square value obtained is 16,322 . These tree factor have degrees of freedom (df) = 6 where the chi-square tabel is 12,592. So as for decision making in the research method, it can be said that H0 is rejected and Ha is accepted which means that there is a relationship between coastal resources and economic, social and environmental factors. Other factors that affect sustainability are government policy information obtained by the Community and community understanding of the sustainable use of coastal resources. The results of the sustainable use of coastal resources will be correlated with applicable government regulations including related factors.

The study examined the insight into utilization of the blue sources of funds for fishery investment in Zanzibar. The study intended to help the blue economy plans in showing the importance of financing fishing sector in order to empower those who are engaged. Using questionnaire and interview collected the primary data. The study applied both (quantitative and qualitative) analyses. Quantitative method was in the form of descriptive statistics using frequency distribution while the qualitative method was in the form of content analysis. The findings of the study showed that funds were utilized in purchasing boats, equipment’s and machines. The results showed that self-finance and retained earnings were used mostly to purchase machines. However government grants were used to purchase boats while loans were used to purchase equipment’s. This implies that most of the fisher folks are very poor to finance themselves to purchase boats explaining why they use government grants to purchase boats. Therefore, the owners of the boats and fisher folks should ensure the effective utilization of funds obtained from different sources for fisheries activities in order to generate higher return on fisheries investments.
