This work is the third installment in a series of publications devoted to the diversity, distribution and ecology of major groups of hydrobionts discovered during the study of meiobenthic communities in inland waters of central and southern Vietnam. Here, a checklist of cladoceran crustaceans (Cladocera) found for the period 2010–2022 is presented,...

This work continues a series of publications on the diversity of the main groups of invertebrates found through the investigation of meiobenthic communities in various inland waterbodies in central and southern Vietnam. Here, a checklist of oligochaetes and aeolosomatids (the annelid worms) discovered for the period 2010–2021 is presented, as well...

This paper presents an annotated list of the Mallomonas and Synura taxa (order Synurales, class Chrysophyceae) found in Viet Nam. This list is based on materials from long-term studies (from 2008 to 2020) of 371 freshwater localities in 18 provinces in the country. A total of 67 taxa (morphotypes) of the genus Mallomonas and 7 of the genus Synura w...

Crab Monomia haanii is a common portunid species in Vietnam. However, the symbiotic fauna of this crab is not studied well. The study on the infestation state of epibiotic pedunculate barnacles on Monomia haanii was conducted in 2019. 694 individuals of M. haanii, including 428 males and 266 females were randomly selected from the catches of fishin...

A new species of the Aeolosomatidae, Aeolosoma vietnamicum sp. n., found in freshwater bodies of Vietnam, is illustrated and described. The new species differs from its congeners in the presence of specific sigmoid chaetae in the dorsal and ventral bundles of all segments, beginning from II. These chaetae are characterized by tips with two apical t...

The food spectrum and trophic and length–weight characteristics of an invasive species, South American suckermouth armored catfishes Pterygoplichthys spp. (Loricariidae), from lotic and lentic inland waters of Vietnam have been studied. It is found that the diet of suckermouth armored catfishes consists of plant and animal food, as well as organic...

Cá khoang cổ lưng yên ngựa (KCLYNN) có tên khoa học là Amphiprion polymnus, đây là loài cá biển có kích thước nhỏ, thường sống cộng sinh với hải quỳ trong rạn san hô, tuy không có giá trị sử dụng làm thực phẩm nhưng lại có giá trị trong nuôi cảnh được nhiều người ưa thích do màu sắc sặc sỡ, dễ thuần dưỡng nuôi trong bể có kích thước nhỏ.

An experimental study of defensive reaction and swimming ability of Nile tilapia from Kamthyong reservoir and its tributary – Suoikok River (Vietnam) was performed. Significant differences in behavioral reactions of fish inhabiting limnic and lotic conditions were found. Nile tilapia from river habitats was characterized by higher swimming ability....

This chapter of the collective monograph gives the basic hydrochemical and some other characteristics of various inland waterbodies of Vietnam investigated in 2008-2010. [In Russian]

The effects of feeding different doses of metabolite combination of L. plantarum RS5, RI11, RG14 and RG11 strains (Com3456) on cholesterol reduction in plasma and breast meat in broiler chickens and the possible mechanism was studied. A total of 504 male Ross broilers were grouped into 7 treatments and offered with different diets: (i) standard cor...

A study was conducted to investigate the effects of feeding medium chain triacylglycerol (MCT) on growth performance, plasma fatty acids, villus height and crypt depth in preweaning piglets. A total of 150 new born piglets were randomly assigned into one of three treatments: i) Control (no MCT); ii) MCT with milk (MCT+milk); iii) MCT without milk (...

Total mercury concentration in water, seston, soils, and muscle tissues of fish in water bodies in Khan Hoa province was determined. Hg concentration in water does not exceed 40 ng/l. It migrates in water mostly in dissolved form. Hg concentration in soils of the examined water bodies varies from 0.01 to 0.05 mg/(kg dry mass) and that in the muscle...

The present paper focuses on flora of silica-scaled chrysophytes from tropical reservoirs in Vietnam. The use of electron microscopy technique allowed for the discovery of 18 taxa in eight reservoirs. In the class Chrysophyceae, two species belonging to two genera (Chrysosphaerella, Paraphysomonas) were found. In the class Synurophyceae, 13 species...

Inhibitory activity of 63 combinations of metabolites produced by 6 strains of locally isolated Lactobacillus plantarum I-UL4, TL1, RS5, RI11, RG14 and RG11 against various pathogens was studied. Inhibitory activities based on the diameter of inhibitory zone were then tested against Pediococcus acidilactici, Escherichia coli, Listeria monocytogenes...

Res., 36: 29–32.To study the effect of worm meal (WM) as partial replacement of soybean and fish meals in the diets, a total of 245 day-old broiler chicks were r...

1. Four combinations of metabolites produced from strains of Lactobacillus plantarum were used to study the performance of broiler chickens. 2. A total of 432 male Ross broilers were raised from one-day-old to 42 d of age in deep litter pens (12 birds/pen). These birds were divided into 6 groups and fed on different diets: (i) standard maize-soybea...
