Comparative study on growth performance between Vietnam koi and Thai koi in mini ponds

Abstract

An experiment was carried out to determine the comparative growth study of Vietnam koi (Anabus testudineus) and Thai koi (Anabus testudineus) for a period of 90 days in eight experimental ponds in the northern side of the Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh. Four treatments were considered having two replicates. For Vietnam koi treatments were named VT 1 and VT 2 and for Thai koi were TT 1 and TT 2 . All the fish were of same age group having mean body weight of 0.30 g. Feeding frequency in all the treatments were two times a day. Fish were fed quality fish feed at a rate of 60% of their body weight for the first thirty days that was gradually reduced to 25% for the next thirty days and 10% till the termination of the experiment. The mean value of water temperature were 29.78 in VT 1 , 30.42 in VT 2 , 30.50 in TT 1 and 29.99°C in TT 2 , dissolved oxygen were 7.21, 7.42 , 7.14 and 7.34 mg/l in VT 1 , VT 2 , TT 1 and TT 2, respectively, mean pH values were 7.42 in VT 1 , 7.29 in VT 2 , 7.50 in TT 1 and 7.45 in TT 2 , ammonia were 0.21, 0.24, 0.28 and 0.23 mg/l in VT 1 , VT 2 , TT 1 and TT 2 , respectively and alkalinity were 200.00, 205.00, 210.00 and 205.00 ppm in VT 1 , VT 2 , TT 1 and TT 2 , respectively. The result of the present study showed that the best weight gain of 80.00 g was observed in VT 1 after 90 days of culture period. Average weight gain (g) were 0.83, 0.88, 0.51 and 0.61; SGR (per day) were 3.93, 3.95, 3.65 and 3.71%; FCR were 1.50, 1.67, 1.70 and 1.90; survival rate were 78.50, 76.50, 90.00 and 82.00% and fish production were 7,839, 15,923, 5,519 and 11,820 kg/ha/3 months in VT 1 , VT 2 , TT 1 and TT 2 , respectively. Growth of both the species was higher in lower stocking densities, whereas, production was increased in higher stocking densities. The present research findings suggested that Vietnam koi has high growth potential in comparison to Thai koi under mini pond culture condition.

Evaluation of breeding and growth performances of crossbreds and backcrossbreds with purebreds of Bangladeshi and Vietnamese climbing perch (Anabas testudineus)

“…The Vietnam‐originated climbing perch is more vigour than the native and Thai climbing perch in terms of growth (Ahmed et al., 2014). A comparative study between native and Vietnam strains reveals that they are morphologically, biologically, and genetically different from each other (Table 8).…”

“…As a consequence, a high‐performing climbing perch with high production and growth was introduced from Vietnam in 2010 with the support from Innovation Consulting (Pvt.) Ltd. and Swiss funded Katalysit (Sarnalata Agro‐Fisheries Ltd., Mymensingh) (Ahmed et al., 2014). The Vietnamese climbing perch grows as much as 250–300 g attaining maximum size of 400 g within 120 days of culture period and has a body colour nearly identical to the native climbing perch (Amin et al., 2015).…”

Assessing the impacts of in-feed probiotic on the growth performance and health condition of pangasius (Pangasianodon hypophthalmus) in a farm trial

“…Over recent decades, probiotics have increasingly been used to mitigate stress and pathogens via different mechanisms, such as improving digestion by supplying exoenzymes and the establishment of beneficial microflora in the digestive tract. Various studies have reported on the use of probiotics in finfish and shellfish aquaculture as alternatives to antibiotics ( Chauhan and Singh, 2019 ; Hoseinifar et al, 2018 ), to enhance growth ( Cruz et al, 2012 ; Ibrahem, 2013 ), to increase feed efficiency ( Ahmed et al, 2015 , 2014 ; Nargesi et al, 2020 ) and improve fish production safety ( Dawood et al, 2019 ; Mohapatra et al, 2013 ). However, the application of probiotics at the nursing stage to assess their immediate impact on fish survival (catfish fries are vulnerable at the nursery stage) and their long-term effect on health and growth performance remains undocumented.…”

Effects of Dietary Silica Nanoparticle on Growth Performance, Protein Digestibility, Hematology, Digestive Morphology, and Muscle Composition of Nile Tilapia, Oreochromis Niloticus

“…Over the last decade, Tilapia (Oreochromis niloticus), the global aquatic chicken, has gained its popularity throughout the world (Abdel-Tawwab et al, 2020) for its compatible characteristics, such as easy to produce seed (Barman and Little, 2011), quick response to artificial feeds (Ahmed et al, 2014;Ogello et al, 2014), a wide range of environmental tolerance (Singha et al, 2020), short crop cycle (Francis and Esa, 2016), nutritive values and larger edible portion with no intermuscular bone (Moesch et al, 2016), and high resistance to physical and biological hazards (Al-Deriny et al, 2020;Chaput et al, 2020;Foysal et al, 2020;Naiel et al, 2020). In the context of the increased feed price because of the increasing cost against the limited protein source, such as fish meal (Nguyen et al, 2020a;Pianesso et al, 2020) and a recession in the farmgate price of tilapia due to supply outstripping the national demand and export barriers for developing countries like Bangladesh (Uddin et al, 2019;Bashar et al, 2021;Haque et al, 2021a;Hasan et al, 2021b), recently dealing with this species in semi-intensive, intensive, and super-intensive commercial culture systems have become a great challenge (Kabir et al, 2019).…”
