The reproductive biology of from the Vietnamese Mekong Delta.

The Squaretail mullet, , is a commercial fish species distributed throughout the Indo-Pacific region. This species tolerates wide variations in salinity, having been reported from both freshwater and marine habitats. Although economically significant, there is little information on its reproduction, especially in the Vietnamese Mekong Delta (VMD), where it is heavily extracted.

Population biology of (Quoy & Gaimard, 1825) in the Mekong Delta, Vietnam.

is widely distributed and plays a vital role in the fisheries in the Mekong Delta (MD), but data on its population biological traits have not been known. Consequently, this study was conducted to provide data on its population biology used for fishing status assessment and fish resources management. Fish specimens were collected using trawl nets in two regions of the Hau River mouth, including northern in Ben Tre and Tra Vinh (BTTV) and southern in Soc Trang and Bac Lieu (STBL).

Population dynamics of (Actinopteri: Gobiidae) in the Vietnamese Mekong Delta.

Spotted green goby is one of the commercial gobies living from brackish to freshwater globally, including the Southwest of Viet Nam, but there is no data on population biological traits used for assessing status of stock. Consequently, the research aimed to provide life history parameters of this fish like asymptotic length ( ), growth coefficient indicator (), exploitation rate (), length at first capture ( ), the maximum age ( ), growth coefficient ('), and mortalities. A total 960 individuals (528 males and 432 females) were caught using trawls at two ecoregions, including Tra Vinh-Soc Trang (TVST) and Bac Lieu-Ca Mau (BLCM), from January to December 2020.

Feeding ecology of (Quoy & Gaimard, 1825) living in the Mekong Delta, Vietnam.

(squaretail mullet) adapts to a wide salt spectrum, grows quickly and is easy to raise with other species, so it is the object of attention in aquaculture. Information on the biology and ecology of the species, diet, in particular, is still scattered. Here, we explore the feeding habit, feeding intensity, and food composition of the squaretail mullet.

Ovarian development, spawning season, size at maturity and fecundity of (Valenciennes, 1837) in the Vietnamese Mekong Delta.

This present study provides an overview of the reproductive traits, including ovarian development, spawning season, size at maturity ( ), and fecundity of - a high economic value fish in the Vietnamese Mekong Delta (VMD). A total of 432 females were collected using trawl nets from January to December 2020 at four sites, including Long Huu-Tra Vinh (LHTV), Trung Binh-Soc Trang (TBST), Dien Hai-Bac Lieu (DHBL), and Tan Thuan-Ca Mau (TTCM). The ovarian diameter was seen to increase from 2.

Monthly variations in growth pattern and condition factor of (Gobiiformes: Periophthalminae) living along the Bassac River in Viet Nam.

(Hamilton, 1822) is a unique mudskipper living in the mudbanks from estuarine to riverine regions in the Vietnamese Mekong Delta (VMD), but there is no data on its growth patterns and condition factors that are helpful for fish resource assessment and adaptation understanding. This study was conducted at five sites, from the lower (Soc Trang province) to middle (Can Tho city) and upper (An Giang province) reaches of Bassac River in VMD, to provide knowledge on growth patterns and condition factors to this mudskippers. Fish samples were caught using traps and hands for 24 months, from July 2017 to June 2019, at these five sites.

Population biological traits of Bleeker, 1853 in the Vietnamese Mekong Delta.

is an amphibious fish living in mudflats from eastern India to Indonesia, including the Vietnamese Mekong Delta. Population biological traits play an important role in fishery assessment, but understanding is limited for this species. In total 1,031 specimens were caught in two regions covering four provinces, including the TVST (Duyen Hai, Tra Vinh and Tran De, Soc Trang) and BLCM (Dong Hai, Bac Lieu and Dam Doi, Ca Mau).

Reproduction ecology of an emerging fishery resource, the amphibious mudskipper , in the Mekong Delta.

Populations of , the Gold-spotted mudskipper, within the Mekong Delta are facing extirpation risks due to indiscriminate harvesting for the growing aquarium and food-fish trade. This study provides some of the first information on reproductive ecology-such as spawning type and season, length at first maturity, and batch fecundity-of this species, to be used in their management. The sex ratio of wild populations, based on 1031 individuals (523 males and 508 females) is 1:1.

Spatiotemporal variations in length-weight relationship, growth pattern and condition factor of Eggert, 1935 in Vietnamese Mekong Delta.

Length-weight relationship (), growth pattern and condition factor () play a vital role in fish resource evaluation and management but data on this is limited for . This is an amphibious fish that lives in the mudflats of the mangrove forests in the Western Pacific regions, including the Vietnamese Mekong Delta (VMD). This paper contributes to the understanding of the , growth pattern and of .

Foraging ecology of the amphibious mudskipper (Gobiiformes: Gobiidae).

The food composition and feeding ecology of fishes living in the intertidal zone play an essential role in understanding the energetic connectivity between terrestrial and aquatic systems. is an amphibious fish species occurring in the intertidal zone, but data on its diet and foraging ecology is still poorly known. This study on was carried out from April 2020 to March 2021 at four sites within the Mekong Delta estuary to define the influence of spatio-temporal factors on the diet of this species.

First reference on reproductive biology of Butis koilomatodon in Mekong Delta, Vietnam.

Background: The key to fishery management is knowing the appropriate reproductive strategies of the targeted fish. For most gobiid species, the iteroparous pattern is dominant compared to semelparity. Albeit Butis koilomatodon plays an important role in the Mekong Delta's food supply, its reproductive biological data have not been known.

An off-seasonal amantadine-resistant H3N2 influenza outbreak in Japan.

An off-season community influenza outbreak with high prevalence of amantadine-resistant influenza A/H3N2 occurred during September-October 2005 in Nagasaki Prefecture, Japan, prior to standard influenza circulation. A total of 48 patients with influenza-like-illness (ILI) visited a clinic during the outbreak and 27 (69.2%) of 39 ILI patients were positive for influenza A with rapid antigen testing (Quick Vue Rapid SP Influ).
