Banten Bay, located in Province near Java Island's northwestern tip, supports abundant mackerel populations (Rastrelliger sp.), a primary fishing commodity impacting coastal communities' livelihoods.Mackerel migratory patterns are sensitive to oceanographic conditions, making them indicators of marine ecosystem health.This study investigates the impact these conditions on catches Bay waters using Aqua Moderate Resolution Imaging Spectroradiometer (Aqua MODIS) data from 2014 2023, combined with catch records Nusantara Fishery Harbor (NFH) Karangantu and analyzed Generalized Additive Model (GAM).The results indicate increased productivity, particularly during west season (October December), coinciding upwelling-driven Chlorophyll-a (Chl-a) rises.Sea Surface Temperature (SST) distribution analysis revealed seasonal fluctuations (29.33°C -31.32°C), supporting aggregation warmer waters.Chl-a levels peaked upwelling seasons, enhancing food availability.Sea depth showed successful at depths around 50-60 m.GAM confirmed SST Chl-a as significant factors, having dominant influence.The effect best-explained provides insights for sustainable fisheries management.

Shortfin mako sharks ( Isurus oxyrinchus ) are apex predators in marine ecosystems, yet the North Atlantic stock has declined drastically. Despite their imperiled status, limited research focused on movement and habitat use of mature individuals Gulf Mexico (also known as America; hereafter Gulf), a region hypothesized to serve gestation parturition grounds. From 2016 2021, 21 (90% or nearing maturity) were satellite-tagged northwestern evaluate suitability, move persistence, environmental drivers influencing these patterns. This study revealed year-round Gulf, particularly west central stem Mississippi River delta (~89.1°W), identifying this area previously unrecognized important habitat. Mako exhibited resident behavior productive shelf shelf-slope waters at sea surface temperatures (SSTs) between 19.6°C 26°C, while transiting was observed SSTs >26°C migration corridors, such Loop Current, during movements through Yucatán Channel Straits Florida. These findings highlight intra-population variability emphasize need manage highly migratory species ocean-basin scale. Developing spatially explicit models that incorporate regional connectivity will be essential for improving management strategies rebuilding efforts vulnerable species.
