To estimate the size of fish taken as prey by piscivorous predators, linear or non-linear relationships between bone measures (pharyngeal, opercula, cleithra, anal and dorsal spine bones, otoliths) and body length were elaborated for eleven Eurasian cyprinid fish species captured in three lakes of Turkey: rudd Scardinius erythrophthalmus, Baltic vimba Vimba vimba, Danube bleak Chalcalburnus chalcoides, gibel carp Carassius gibelio, roach Rutilus rutilus, silver bream Blicca hjoerkna, common… Expand
Relationships between fish length and otolith size for five cyprinid speciesfrom Lake Ladik, Samsun, Turkey
The results showed that reliable original size estimates of all species studied are obtainable from their otolith biometrics and can be useful for investigators examining food habits of piscivorous fauna and sizes of these fishes in archaeological samples. Expand
The use of otolith shape and morphometry for identification and size‐estimation of five wrasse species in predator‐prey studies
For all investigated wrasses, except for S. rostratus, otolith length showed the strongest and otolith thickness the weakest relation to both fish length and weight, and multiple linear regression equations based on log transformed variants explained higher proportion of variation in fish size than simple linear regressions.

Otolith Biometry-Body Length Relationships in Four Fish Species (Chub, Pikeperch, Crucian carp, and Common Carp)
In cyprinid fishes, sagittal otolith weight was the best predictor of fish length, and the lapillus length had the highest coefficient of determination among lapillus measurements for the same species. Expand
Relationships between fish size and otolith size of four bathydemersal fish species from the south eastern Arabian Sea, India
These relationships between otolith size and fish size are a helpful tool in predicting fish size from the otoliths and in calculating the biomass of these less-studied fish species during feeding studies and palaentology. Expand
Relationship between fish length and otolith length and width in the lutjanid fish, Lutjanus bengalensis (Lutjanidae) collected from Muscat City coast on the Sea of Oman
Abstract Otoliths are usually used to identify fish species, to estimate their age and their size. This information is useful for studies like population management, feeding habits and archaeology.Expand
Fish length and otolith size of in Nemipterus randalli Russel, 1986 (Actinopterygii: Perciformes: Nemipteridae) collected from Gökova Bay, Turkey
Otoliths have been proved an appropriate tool to identify fish species, and they have been in use in studies of prey-predator relationships, population dynamics and ichthyo-archaeology. In addition,Expand
Relationships between fish length, otolith size and otolith weight in Sperata aor (Bagridae) and Labeo bata (Cyprinidae) from the Ganga River, India
Investigation of the relationships between fish length, otolith size and otolith weight in S. aor and Labeo bata from the River Ganga revealed that fish length is potentially related to otolithsize and a strong relationship between fishlength and otolithic size exists in both species. Expand
Relationships Between Fish Length Otolith Size of Diplodus vulgaris from Boughrara and El Bibane Lagoons (Southeastern Tunisia)
A strong relationship between otolith weight and total length of Diplodus vulgaris, reflect that sagittal weight could be used as the best predictor of fish length. Expand
Relationships between fish and otolith size of the Indian Ruff Psenopsis cyanea (Alcock 1980) collected from the south eastern Arabian Sea coast of India
Length weight relationships and regressions between otolith size (length, width, size and aspect ratio) and fish length and weight of the bathy pelagic fish Psenopsis cyanea collected from ArabianExpand
Otolith dimensions and their relationship with the size of Glossogobius sparsipapillus fish along the coastline of Mekong Delta, Vietnam
Glossogobius sparsipapillus Akihito & Meguro, 1976 is one of three goby species belonging to the Gobiidae family recorded in the Mekong Delta (Tran et al., 2013). The species G. sparsipapillus livesExpand
