Temperature plays a profound role in organismal growth, immunity, survival, and the entire biological systems of any aquatic species. Suboptimal temperature changes modify different traits fish that adversely affect their life cycle aquaculture productivity. The freshwater Indian major carp, Rohu (Labeo rohita), is one most important species across Sub-continent, with optimum range 28 °C to 32 °C. This study tested effects five levels (28 °C, 30 33 34 °C) on selected physiological...
Abstract Inland aquaculture contributed by three major fish groups, including carps, tilapias, and catfish plays a vital role in global food security nutrition, particularly low middle‐income countries. However, the sustainable development of this sector is hampered disease epidemics, especially those caused bacteria such as Aeromonas species. At least eight pathogenic motile species ( A. hydrophila , veronii jandaei caviae sobria bestiarum dhakensis schubertii ) have been reported with some...
The aim of this study was to investigate the antimicrobial activity guava (Psidium guajava) and star gooseberry (Phyllanthus acidus) leaf extracts their effects as dietary supplements on growth performance, intestinal (hindgut) microflora composition, immuno-hematological parameters, disease resistance Nile tilapia (Oreochromis niloticus) against Aeromonas hydrophila. Three hundred sixty (8.9 ± 0.2 g/fish) were randomly distributed into twelve aquaria (30 fish per aquarium) within a...
The present study aimed to investigate the effects of
All-male monosex culture of Macrobrachium rosenbergii (De Man) has emerged as a popular practice in India, especially the state Andhra Pradesh. A study was conducted to compare economics all-male, mixed and all-female 15 adjacent, rectangular ponds 4000 m2 each by stocking juveniles previously reared nursery for 60 days. The experiment using completely randomized design with three treatments; T1 (all male), T2 (mixed) T3 female), five replicates period 5 months after phase. Statistical...
Seawater (SW)-acclimatized Oreochromis niloticus (in 27 - 30 ppt) has been generated for more than 10 generations in a private farm Thailand, and it was noted that the muscle of fish softer reared under freshwater (FW) 0 3 ppt). We hypothesized high lipid content might be cause. Proximate analysis from FW O. SW revealed significantly higher (P < 0.05) fish. The also had hepatosomatic index (HIS), mesenteric adipose tissue somatic index, liver (all, P 0.05), compared to Liver histology 2...
Freshwater prawn production in India that includes farming and wild capture of the giant freshwater prawn, Macrobrachium rosenbergii monsoon river M. malcolmsonii has increased steadily since 1999 reaching a peak output 42 780 t 2005, but then declined to 6568 2009–2010. Stunted growth diseases ponds because poor seed quality broodstock which had been inbred over several generations; pond water issues; cost on account feed, labour mandatory certification requirements are suggested be some...
A novel method, BBD-SSPD is proposed by the combination of Box-Behnken Design (BBD) and Split-Split Plot (SSPD) which would ensure minimum number experimental runs, leading to economical utilization in multi- factorial experiments. The brine shrimp Artemia was tested study combined effects photoperiod, temperature salinity, each with three levels, on hatching percentage time their cysts. BBD employed select 13 treatment combinations out 27 possible that were grouped an SSPD arrangement....
Drought is a major abiotic stress limiting growth and productivity of field horticultural crops. Exogenous application silicon (Si) arbuscular mycorrhizal fungi (AMF) inoculation has the potential to alleviate adverse effect drought on plant. A factorial experiment consisting four monosilicic acid (MSA) doses (0, 75, 150 300 kg ha−1), two levels AMF (inoculation [+AMF] without [–AMF]) three soil moisture regimes (100%, 75% 50% capacity [FC]) was conducted evaluate Si growth, yield water rice...
Abstract Seahorses ( Hippocampus spp.) are a major commodity fished from the shallow coastal seas of south coast India where there is an abundance sea grasses, sponges and corals. They in great demand for export as traditional medicines, curios aquarium fish. Organised fishing trade seahorses exists along Palk Bay Gulf Mannar coasts. At coast, targeted by divers with cucumbers Holothuria gastropods (e.g. Murex spp., Xancus pyrum Hornell). In Mannar, most landed bycatch shrimp trawling. also...
The rural farmers in western Rajasthan State are uneducated and most of the applications Information Communication Technology (ICT) demonstrated run English Language. majority these who illiterates with a very low level understanding Language find it difficult to take advantage availability ICT facilitate their access information for farm businesses. This study examined role enhancing farmers’ production marketing India. Primary data was collected from 133 consisting 71 users 62 Non-ICT...
Determining the optimum levels of macroalgal density and salinity for removing aquaculture effluent has gained increasing research interest in recent years because growing concerns over environmental sustainability. Here, we determined effects on uptake NO2−, NO3−, NH3, PO43− by Caulerpa lentillifera from Poecilia latipinna using spectrophotometry. Laboratory experiments were conducted to measure nutrient at five different (10, 20, 30, 40, 50 g/L) three (20, 40 ppt) with without aeration....
