Hide and seek in the open sea: pelagic camouflage and visual countermeasures.

Essential fish habitats (EFH) of small pelagic fishes in the north of the Persian Gulf and Oman Sea, Iran

Small pelagic fishes particularly anchovy (Encrasicholina punctifer) and sardine (Sardinella sindensis) have an important role to support the Iranian fisheries, and are distributed along the entire length of the Persian Gulf and Oman Sea coastal waters. Using small pelagic fisheries logbook, a GIS-based environmental modelling approach was applied to investigate the presence and abundance of an...

Short communication: Study on heavy metals (Chromium, Cadmium, Cobalt and Lead) concentration in three pelagic species of Kilka (Genus Clupeonella) in the southern Caspian Sea

Use of Hyperspectral Imagery to Assess Cryptic Color Matching in Sargassum Associated Crabs

Mats of the pelagic macroalgae Sargassum represent a complex environment for the study of marine camouflage at the air-sea interface. Endemic organisms have convergently evolved similar colors and patterns, but quantitative assessments of camouflage strategies are lacking. Here, spectral camouflage of two crab species (Portunus sayi and Planes minutus) was assessed using hyperspectral imagery (...

Significant changes in pelagic fish stocks of Clupeonella spp. in the south Caspian Sea

 The present study was carried out during 2006-2007 along the southern Caspian Sea. The species composition showed that the common kilka, Clupeonella cultriventris caspia, is dominant species with 89% and then anchovy, C. engrauliformis, has shown only 8.7% while it was already dominant species in the past decades. The overall results indicated that common kilka was replaced with anchovy kilka ...
