“…On the contrary, individuals from the ION showed significantly heavier left otoliths than individuals from the AEG of the same length (P ANCOVA =0.0195, F=5.57) (Table 1, Figure 1); this may be related either with the existence of a higher number of smaller individuals caught in the AEG or with the existence of different population stocks, as it has been assumed for the red mullet (Anastasopoulou et al, 2016). In any case, a strong and positive relationship was observed between OW-OR, OR-TL and OW-TL, confirming previous results for other species (Zan et al, 2015;Anastasopoulou et al, 2016). …”

“…Otolith weight (OW) is an important attribute that has been explored for population identification, aging and feeding studies as well as stock assessments for many fish species (Zan et al, 2015). This study provides information on the relationships between otolith dimensions -including otolith weight-and fish length in the common pandora (Pagellus erythrinus), a demersal fish whose geographic distribution is expanding throughout the Mediterranean Sea and the eastern coasts of the Atlantic Ocean (Fisher et al, 1987).…”

In this collective article we discuss the relationships between the otolith measurements (weight, radius) and total length of Mullus surmuletus in the Aegean and Ionian Seas and of Pagellus erythrinus samples caught in the Southern Aegean Sea. In addition to the above mentioned studies, the abundance of the rare fish Echiodon dentatus in the Kyklades islands and the Saronikos Gulf (Central Greece) is also documented. The first weight-length relationship of the alien northern brown shrimp Penaeus aztecus from the Central Aegean Sea is given at the end.

“…Otoliths are used in stomach content studies because they are among the species-specific features last to be digested by piscivorous predators (e.g., fish, sea birds, marine mammals); thus, otoliths can be used as a tool for reconstructing predator diet and estimating the size of preyed fish (e.g., Granadeiro & Silva 2000, Harvey et al 2000, Longenecker 2008, Kasapoglu & Duzgunes, 2013, Lalas et al 2014, Zan et al 2015. Overall, the relations described in this work for lionfish in the PNAA can provide baseline data to detect lionfish presence and calculate its size based on otoliths found in stomachs of potential fish predators (i.e., groupers, snappers, jacks).…”

Abstract.-Described are the relations between fish length to weight, and otolith length and weight, of the lionfish (Pterois volitans) collected by diver-fishermen volunteers between 2011 and 2013 in a natural protected area (Parque Nacional Arrecife Alacranes) off the northern Yucatan Peninsula, Mexico. High correlations were detected between fish length and otolith length. Significant differences in the length-weight relations were found for males and females. Length of lionfish can be estimated from otolith length and weight. This study will be helpful in diet content studies of potential predators of lionfish helping to discern the size of lionfish consumed when otoliths are found in stomachs of predators.

Otolith telah digunakan secara luas untuk kajian taksonomi, pertumbuhan, umur dan kekerabatan populasi ikan dari perairan yang berbeda. Penelitian ini bertujuan untuk mengetahui hubungan morfometrik otolith dan ukuran ikan lemuru serta karakteristikmorfologi otolith. Sampel dikumpulkan dari Selat Bali padaApril hingga Juli 2015. Pengujian statistik juga dilakukanmenggunakan uji-t berpasangan dua arah pada selang kepercayaan 99% untuk menentukan signifikansi hasil pengukuran morfometrik antara otolith kanan dan kiri. Hubungan parameter morfometrik dan ukuran ikan dianalisis menggunakan persamaan regresi linear dan eksponensial. Karakteristik morfologi otolith disajikan secara deskriptif dan dipertegas dengan nilai indeks-indeks bentuk menggunakan 6 deskriptor. Hasil penelitian menunjukkan bahwa tidak ada perbedaan yang signifikan pada pengukuran morfometrik otolith kiri dan kanan. Ukuran otolithmemiliki korelasi isometrik dengan pertumbuhan ikan dimana panjang otolith (OL) menjadi indikator terbaik untuk mengestimasi ukuran individu ikan. Otolith ikan lemuru memiliki ciri-ciri morfologi yang konsisten seperti halnya ikan dari genus Sardinella, khususnya sulcus acusticus, rostrum dan antirostrum. Nilai indeks bentuk yangmenegaskan ciri-ciri morfologi otolith juga dijelaskan.Otoliths widely used to determine taxonomy, growth, age and population structure of fishes. This study aims to determine the relationship between otolith morphometric to fish sizes and morphological characteristic of otolith. Data were collected from April to July 2015 in Muncar, Bali Strait. The statistical tests using two tails ttest paired sample also implemented to examine differentiation between left and right otolith measurement. The linear regression and exponential equation used to examine otolith morphometric parameter to fish size. Otolith morphological characteristics presented descriptively and emphasized using 6 descriptors of shape indices. The results showed no significant differences between left and right otolith. The otolith-fish size relationship was isometric. An OL (length of otolith) found as the best indicators to estimate the original size of fish. The otolith has specific morphological characteristics, in particular sulcus acusticus, rostrum and antirostrum were similar with other species from Sardinella genus. Shape indices also provided to confirm the morphological otolith.
