Length-weight Relationship of Five Demersal Fish Species in Guinea Bissau (CE Atlantic)Thalassas: An International Journal of Marine Sciences - Tập 39 - Trang 1125-1129 - 2023
Alba Jurado-Ruzafa, Carlos Hernández-González
Length-weight relationships (LWR) were determined for Brotula barbata, Dentex angolensis, Dentex macrophthalmus, Neomerinthe folgori and Scorpaena stephanica using individual fish records collected between July 2002 and January 2003, during a pilot project of experimental fishing over the shelf off Guinea Bissau. Fishes were caught by commercial vessels using bottom longline, measured defrost for ...... hiện toàn bộ
Range Extension of the Japanese Hooked Squid Onykia loennbergii (Cephalopoda: Onychoteuthidae) to the Arabian SeaThalassas: An International Journal of Marine Sciences - Tập 39 - Trang 1047-1053 - 2023
Kurichithara K. Sajikumar, P. Laxmilatha, Mathew Joseph, Kolliyil S. Mohamed
The occurrence of the Japanese hooked squid Onykia loennbergii in the Arabian Sea is reported here based on reexamination of a previously collected and misidentified specimen in the course of research on oceanic cephalopods from the Arabian Sea. The individual’s dorsal mantle length (DML) measured 325 mm and it weighed 493 g. The individual was a mature male with a relatively long penis (165 mm) w...... hiện toàn bộ
Calmodulin Highly Expressed during the Formation of Pearl Sac in Freshwater Pearl Mussel (Hyriopsis schlegelii)Thalassas: An International Journal of Marine Sciences - Tập 34 - Trang 219-225 - 2017
Kou Peng, Fang-lan Liu, Jun-hua Wang, Yi-jiang Hong
Calmodulin (CaM) is a pivotal multifunction regulator of calcium metabolism in nearly all organisms, and earlier studies revealed its underlying involvement of shell or pearl formation in oysters. Culture pearls are formed within complete pearl sacs. However, whether CaM functions in pearl sac formation or not is not reported. In this study, we prepared a polyclonal antibody against the CaM from t...... hiện toàn bộ
Evaluating the Fish Community of “Los Petenes” Biosphere Reserve, Campeche, Mexico, through the Characteristics of the Environment and Indicators of Taxonomic DiversityThalassas: An International Journal of Marine Sciences - - 2020

The coastal zone of Los Petenes” Biosphere Reserve, is a critical breeding habitat for many species, particularly fish. Despite its low anthropic impact, development on the coastal area around the reserve is gradually increasing and fishing activities continue to grow; however, there are few studies on fish communities and the characteristics of their environment. In addition, there are no referen...... hiện toàn bộ
A Stranding Record of Dwarf Sperm Whale Kogia sima in Lakshadweep Archipelago, India and its Genetic Analogy by Molecular PhylogenyThalassas: An International Journal of Marine Sciences - - 2018

The distribution of Kogiid whales from the Indian Ocean waters, especially Indian waters are poorly known. It is extremely difficult to differentiate the two species (Kogia sima and K. breviceps) based on their morphological characteristics alone. Our study presents the first confirmed record of dwarf sperm whale Kogia sima from the Indian waters using morphological examinations, skull morphology ...... hiện toàn bộ
Eastern Tropical Atlantic Mixed Layer Depth: Assessment of Methods from In Situ Profiles in the Gulf of Guinea from Coastal to High SeaThalassas: An International Journal of Marine Sciences - Tập 36 - Trang 201-212 - 2019
Benjamin Kouadio N’Guessan, Aka Marcel Kouassi, Albert Trokourey, Elisée Toualy, Desiré Kouamé Kanga, Patrice Brehmer
To assess the eastern Atlantic tropical mixed layer depth (MLD) at 4°W in the Gulf of Guinea, water temperature and density profiles from over five hundred historical observational Conductivity – Temperature - Depth (CTD) data were used. These data, obtained from key oceanographic survey databases covering 60 years (1956 to 2016) were used for a numerical and visual determination of the MLD. The n...... hiện toàn bộ
Demographics and Reproductive Characteristics of Orange Chromidae, Pseudetroplus maculatus (Bloch, 1975) from Cochin Estuary, Southern IndiaThalassas: An International Journal of Marine Sciences - Tập 37 - Trang 905-915 - 2021
Kuttanelloor Roshni, Chelapurath Radhakrishnan Renjithkumar
Demographics and reproductive characteristics of Pseudetroplus maculatus (Bloch, 1795) in Cochin Estuary situated on the South-west coast of India were studied during June 2015 to May 2016. A total of 710 individuals (male = 392 and female = 318) were collected from the Cochin Estuary having TL and BW ranging from 43.2–93.2 mm and 1.45–13.64 g respectively were used for the study.
