Kiluan Bay is one of the marine conservation areas in Tanggamus Regency, Province of Lampung through which dolphins migrate. This research aims to analyze the relationship between the distribution of sea surface temperature and chlorophyll with the appearance of dolphins in Kiluan Bay. This research uses an exploratory survey method. The research results show that the highest appearance of dolphins was in the Transition Season I, around 117 in the temperature range of 29,44-29,88°C with a chlorophyll concentration of 0,120-0,184 mg/m³ and the lowest in the West Season was around 31 in the temperature range of 28,56-29,34°C with a chlorophyll concentration of 0,096-0,134 mg/m³. The appearance of dolphins is more strongly related to sea surface temperature than to chlorophyll concentration because dolphins do not eat phytoplankton directly where there is a time lag where increasing the chlorophyll concentration value does not immediately have an impact on increasing the intensity value of dolphin emergence, but requires some predation time.

Yellowstripe scad (Selaroides leptolepis) is a type of pelagic fish that is dominantly caught in the waters of Lampung Bay and is landed at the Lempasing Coastal Fisheries Harbor. The high market demand for yellowstripe scad means fishing for this fish is carried out throughout the year. The aim of this research was to analyze the population dynamics of yellow trevally (Selaroides leptolepis) in the waters of Lampung Bay. The yellow trevally fish collected during the research came from fishermen's catches in the waters around Lampung Bay. The study's findings demonstrated that the yellow trevally's development pattern was negative allometric, and its condition factor value varied between 0.7509 and 1.0842. the growth parameters of yellowstripe scad obtained an asymptotic length (L∞) value of 152 mm, the growth coefficient (K) of 0.57/year, and theoretical age (t0) of -0.2191 years. Yellow trevally have a natural mortality value (M) of 0.80 per year, a fishing mortality value (F) of 1.12 per year, and a total mortality value (Z) of 1.92/year. Yellowstripe scad recruitment peaked in the Sunda Strait between May and September, at 18.19% and 13.90%, respectively.

Changes in the area and density of mangroves have a major impact on the sustainability of ecosystem functions in coastal areas. This study aims to analyze changes in the area and density of mangroves in Serang City, Banten. The method used is remote sensing through interpretation of Landsat 5 and Landsat 8 images with analysis of changes in the area and density of mangroves in 2011 and 2021. The research procedure was carried out by grouping NDVI values into 3 vegetation classes: sparse, moderate, and dense. Furthermore, a ground check was carried out to test the level of data accuracy against mangrove canopy cover using the hemispherical photography method. The results showed that the level of image accuracy in 2021 was 90%. Based on this analysis, it is known that there has been a decrease in the area and changes in mangrove density in Sawah Luhur Village, while in Banten Village it has increased. In general, in the coastal area of Serang City, there was a decrease in the mangrove area between 2011-2021 which reached 13.95 ha with the main decrease occurring in mangroves with sparse vegetation class (33.14 ha). In contrast, mangroves with medium and dense density categories increased to 19.19 ha. The decrease in mangrove area was due to abrasion, conversion into ponds, and illegal logging. The results of the analysis also showed that the correlation between NDVI values and the percentage of canopy cover had a value of 0.696 which was included in the strong category.

Green mussel (Perna viridis) has filter-feeding habits and a sessile way of life, with the main food components of plankton and organic matter in the waters. These food components can contaminate green mussels when it accumulates heavy metals. Therefore, this study aims to evaluate heavy metals content and the bioconcentration of lead (Pb), mercury (Hg), and cadmium (Cd) in green mussels based on different sizes and ages. The study was conducted on Pasaran Island, Lampung, Indonesia, and used green mussels aged 3, 5, 7 to 9 months as samples, with 2 replications. The AAS (Atomic Absorption Spectrophotometry) method was used in the analysis of Pb, Hg, and Cd, sampling technique used purposive sampling. The result showed that green mussels at different ages and sizes has impact on Pb content, while an increase of one unit of age and size of green mussels has no effect on the metal content of Hg and Cd. Furthermore, the highest bioconcentration of Pb and Hg was obtained at 9 months, while Cd was observed at 3 months. Based on the results of this study it can be concluded that the simple linear regression appropriate a functional relationship between Pb and the different ages and sizes green mussels cultivated on Pasaran Island , while heavy metals Hg and Cd appropriate with a polynomial quadratic approach and almost do not exist in the form of a functional relationship between Hg and Cd with the different ages and sizes green mussels. Even though it contains heavy metals in below the maximum limit, but care needs to be taken in addressing this phenomenon due to its nature heavy metals that can accumulate in living tissue, thus consuming green mussels containing heavy metals even in relatively small amounts is not recommended.Keywords:Filter feederSessileAccumulateOrganic matterContaminate

Megalaspis cordyla, locally known as ikan bekre, stands as a crucial economic species commonly consumed by the people of Lampung. The escalating demand for this fish has significant implications for increased fishing activities, potentially impacting its population. This research aimed to explore the biological characteristics of M. cordyla landed at the Lempasing Fishing Port, Bandar Lampung, providing fundamental insights for fisheries resource management in the waters of Lampung Bay. Using a quantitative descriptive method, the sampled fish has been analyzed to get size structure, growth type, and fish condition factors based on length and weight data collected from M. cordyla landed weekly. Between April and June 2022, a total of 300 samples were collected, with length ranging from 230 to 430 mm TL, with the largest count (77 individuals) in the 314-334 mm interval. M. cordyla has an allometric negative growth pattern in Lampung Bay, with a growth coefficient (b) value of 2.47. Fish condition factor values ranged from 0.71 to 1.33, with June having the highest average value of 1.03. This information contributes greatly to a better understanding and long-term planning for the management of this fish population.Keywords: Allometric; Condition Factor; Length-Weight Relationship; Pelagic Fish; Aquatic Resources Management
