Surgeonfish of the genus Acanthurus (family Acanthuridae) are ecologically pivotal herbivores on Indo-Pacific coral reefs, yet their habitat requirements and distributional responses to environmental gradients and climate change remain poorly characterized in the Philippines. A Random Forest (RF) machine learning framework was used to model habitat suitability for six commercially and ecologically…
Fisheries management measures are expected to enhance the demographic structure and reproductive capacity of exploited fish populations, particularly in short-lived, fast-growing small pelagic species. We evaluated long-term changes in key demographic traits of common sardine ( Strangomera bentincki ) off central-southern Chile in relation to major regulatory milestones implemented between 1991…
A single female specimen (195 mm TL) of the alligator pipefish, Syngnathoides biaculeatus (Bloch, 1785) was recorded from the coral reef rubble habitats of Gandhi Nagar, Great Nicobar Island. The present study provides a detailed morphological description of the species, including comprehensive morphometric measurements and meristic counts. This record represents important baseline information on…
Lithodes santolla is a key benthic resource in the Patagonian region of South America, sustaining major fisheries in Chile and Argentina. Assessing population condition is essential, as it influences recruitment dynamics and informs sustainable management. This study evaluated energy allocation and physiological condition in adult females during the pre-reproductive period. Samples were collected…
Undaria pinnatifida (Harvey) Suringar 1873 is a marine brown macroalga of the order Laminariales, native to northern Asia. This species has an invasive behaviour, currently present on several coasts worldwide, including Argentina. Along the coast of Mar del Plata (Buenos Aires province), sporophytes of U. pinnatifida have been found growing within the local harbour area, but no information is…
