The utilization of waste as raw materials in the production functional is a growing area interest to promote global sustainable growth. This work studied microstructure, chemical properties, and phosphorus (P) dissolution efficiency carbon/hydroxyapatite (HAP) nanocomposites derived from fish scale wastes, namely FSBCs. Tilapia scales were pyrolyzed at different temperatures (450–600 °C) perfor...

Atlantic salmon Salmo salar are extensively farmed throughout their natural range, and unintentional interactions between farmed fish and wild populations have been implicated in the decline of wild salmon. The trace element composition of salmon scales distinguishes wild from farmed fish, and potentially provides a rapid and cheap method to assess the extent of escaped farmed fish within a wil...

The main goal of the study was to obtain field data to build a baseline of fish assemblage composition that can be used comparatively for future analyses of the impact of human actions in the region. A basic network of 68 sampling stations was defined for the entire region (4,050 km2). Fish assemblage species and size composition was estimated using visual census methods at three different spat...

The trace fossil Lepidenteron lewesiensis (Mantell 1822) provides an exceptional taphonomic window to diversity of fishes as shown for the Upper Cretaceous of Poland, in the Middle Turonian-Lower Maastrichtian deposits of the Opole Trough, Miechów Trough, Mazury-Podlasie Homocline, and SE part of the Border Synclinorium. Lepidenteron lewesiensis is an unbranched burrow lined with small fish sca...

Garra rufa is one of the most popular therapeutic and commercially important fish in ichthyotherapy. Otolith and scale morphology provide new and useful information for fish identification and classification. Left-right asteriscus and lapillus otoliths from juvenile and adult doctor fish, and the scales from 6 different regions of the juvenile and adult fish body have been examined in Kangal Ba...
