The parasitic fatma of the alimentary tract of adult whi tespotted rabbitfish, Siganus sutor, sampled in December 1990 at the Kenyan coast, was in vestigated. Fi ve endoparasites were fo und: the di genean trematodes Opisthogonoporoides hanwnanthai, Gyliauchen papillatus and 1-/exan.gium sigani, the acanthocephalan Sclerocollum rubrimaris and th e nematode Procamm.alanus elatensis. No uninfected fish, nor single species infections occurred. Parasite population data showed ve1y hi gh prevalences for ali endoparasites, ranging from 68. 18 % to 100 %. G. papi/lat us occurred with the hi ghest mean intensity, 201.68 ± 12 .54 parasites per infected fi sb. The parasites were over di spersed within their host's population and frequency distributions generall y fitted the n egative binomial function. The relationship between host size and parasite burden showed that smaller fish were more heavil y infected. The infection with O. hanumanthai and H. sigani decreased significant ly with total length of S. su tor. Study of th e associations between parasites showed that the iutensi ties of the three digenean species were significantly positi ve!y correlated.

Ctenophore Relationships and Their Placement As the Sister Group to All Other Animals
ARTICLES DOI: 10.1038/s41559-017-0331-3 Ctenophore relationships and their placement as the sister group to all other animals Nathan V. Whelan 1,2*, Kevin M. Kocot3, Tatiana P. Moroz4, Krishanu Mukherjee4, Peter Williams4, Gustav Paulay5, Leonid L. Moroz 4,6* and Kenneth M. Halanych 1* Ctenophora, comprising approximately 200 described species, is an important lineage for understanding metazoan evolution and is of great ecological and economic importance. Ctenophore diversity includes species with unique colloblasts used for prey capture, smooth and striated muscles, benthic and pelagic lifestyles, and locomotion with ciliated paddles or muscular propul- sion. However, the ancestral states of traits are debated and relationships among many lineages are unresolved. Here, using 27 newly sequenced ctenophore transcriptomes, publicly available data and methods to control systematic error, we establish the placement of Ctenophora as the sister group to all other animals and refine the phylogenetic relationships within ctenophores. Molecular clock analyses suggest modern ctenophore diversity originated approximately 350 million years ago ± 88 million years, conflicting with previous hypotheses, which suggest it originated approximately 65 million years ago. We recover Euplokamis dunlapae—a species with striated muscles—as the sister lineage to other sampled ctenophores. Ancestral state reconstruction shows that the most recent common ancestor of extant ctenophores was pelagic, possessed tentacles, was bio- luminescent and did not have separate sexes. Our results imply at least two transitions from a pelagic to benthic lifestyle within Ctenophora, suggesting that such transitions were more common in animal diversification than previously thought. tenophores, or comb jellies, have successfully colonized from species across most of the known phylogenetic diversity of nearly every marine environment and can be key species in Ctenophora. -

Diversity and Length-Weight Relationships of Blenniid Species (Actinopterygii, Blenniidae) from Mediterranean Brackish Waters in Turkey

(2019). Diversity and length-weight relationships of Blenniid Species (Actinopterygii, Blenniidae) from Mediterranean Brackish Waters in Turkey. Aquatic Sciences and Engineering, 34(3), 96-102. ABSTRACT This study aims to determine the species composition and range of Mediterranean Blennies (Ac- tinopterygii, Blenniidae) occurring in river estuaries and lagoon systems of the Mediterranean coast of Turkey, and to characterise the length–weight relationship of the specimens. A total of 15 sites were surveyed from November 2014 to June 2017. A total of 210 individuals representing 3 fish species (Rusty blenny-Parablennius sanguinolentus, Freshwater blenny-Salaria fluviatilis and Peacock blenny-Salaria pavo) were sampled from five (Beşgöz Creek Estuary, Manavgat River Es- tuary, Karpuzçay Creek Estuary, Köyceğiz Lagoon Lake and Beymelek Lagoon Lake) of the locali- ties investigated. The high juvenile densities of S. fluviatilis in Karpuzçay Creek Estuary and P. sanguinolentus in Beşgöz Creek Estuary were observed. Various threat factors were observed in five different native habitats of Blenny species. The threats on the habitat and the population of the species include the introduction of exotic species, water ORCID IDs of the authors: pollution, and more importantly, the destruction of habitats.

A Preliminary Study on the Reproduction of the Rabbitfish (Siganus Rivulatus (Forsskal, 1775)) in the Northeastern Mediterranean
Turk J Zool 24 (2000) 173–182 © TÜBİTAK A Preliminary Study on the Reproduction of the Rabbitfish (Siganus rivulatus (Forsskal, 1775)) in the Northeastern Mediterranean Hacer YELDAN, Dursun AVŞAR Fisheries Faculty, Çukurova University, P.O. Box 173, Tr 01330 Balcalı, Adana-TURKEY Received: 23.03.1999 Abstract: This study was carried out to identify some aspects of the reproductive cycle of the rabbitfish (Siganus rivulatus) inhabiting the northeastern Mediterranean. For this reason, monthly sampling was conducted between February 1995 and June 1996, and a total of 473 specimens were used. By using the monthly changes in the values of the gonadosomatic index (GSI) and Condition Factor (K), it was found that their reproduction takes place during July and August. The mean diameter of ripe gonadal eggs was 0.44 mm; and mean fecundity and its standard deviation was found to be 434761±181006. Fecundity-total length, fecundity-total weight and fecundity-age relationships were also estimated using regression analysis as follows: Total Length (cm) F= 0.49 * L4.61 (r= 0.96) Total Weight (g) F= -57584.67 + 4851.96 * W (r= 0.96) Age (years) F= -1029631.33 + 255261.18 * A (r= 0.64) Key Words: Northeastern Mediterranean, Rabbitfish (Siganus rivulatus), Reproduction.
