“…Fish are more aggressive when maggot as a live feed has given. This result is similar to the reported study by Roy et al [13] that snakehead fish prefer eating live food to pellets because the movement of live feed can trigger the feeding response and satisfy the predator instinct. Consequently, a higher growth rate can be achieved by using live feed.…”

Snakehead fish (Channa striata) is a carnivorous freshwater fish commodity that has high economic value. However, this cultivation takes a long period due to its poor growth rate. Maggot has been proposed as a possible alternative to fish feed because it is less expensive and has nutritional value. This study aimed to determine the effect of the dietary combination of maggot and pellets on the growth rate and feed conversion ratio of snakehead fish. This study used a completely randomized design (CRD) with five treatments and four replications. The treatments were P0: 100% pellet, P1: 100% maggot, P2: 75% pellets and 25% maggot, P3: 50% pellets and 50% maggot, P4: 25% pellets and 75% maggot. The result showed a combination of pellet feed and maggot feed had a significant improvement (p<0.05) on the growth rate of snakehead fish. However, there were no significant differences in the feed conversion ratio (p>0.05). The treatment of 75% pellet feed and 25% maggot feed (P2) generated the highest growth rate of 0.154 g/day and the lowest feed conversion ratio of 3.121. It can be concluded that the combination of maggot and pellet experienced better growth performance and feed conversion ratio of snakehead fish.

“…Proper nutrition also correlates with health issues and immunity. Therefore, the wrong selection of feed types, grain size, and feeding regime can adversely affect the growth and survival of fish (Dawood, 2021; Roy et al, 2020). Improper feeding can also increase cannibalism in several cultured species (Chandan et al, 2021; Roy et al, 2020).…”

Improper feeding can also increase cannibalism in several cultured species (Chandan et al, 2021; Roy et al, 2020). Additionally, farms often over‐ or under‐use chemicals and medicines that worsen the survival, growth, and health issues of fish (Anik et al, 2021; Faruk et al, 2004; Heal et al, 2021).…”

Aquaculture is one of the most prominent sectors of Bangladesh regarding nutrition, livelihood, and revenues. Although this nation has made promising improvements in aquaculture, several existing and imminent challenges can disrupt further development. Until now, no studies have extensively reviewed the existing aquaculture practices of this nation. Thus, this article elucidates the prospects, production, and problems of common aquaculture practices for the establishment of sustainable aquaculture in Bangladesh. The culture units are mainly natural bodies of water including earthen ponds, seasonal floodplains, baor, and gher. Although pond farming is the oldest and most dominant practice in this nation, the use of pen and cage cultures has also been intensified in the last decade. Regarding farmed fish species, indigenous major carps, exotic carps, tilapia, pangas catfish, and climbing perch are the major runners. Among crustaceans, giant freshwater prawns and tiger shrimp are the leading farmed species. Mud crab, biofloc, and seaweed farming are a growing focus that can evolve as artisanal and commercial‐scale farming practices in the near future. Major challenges that are potent enough to impede the establishment of viable aquaculture practices in Bangladesh are inadequate seed production, disease outbreaks, climate change, mediocre management practices, and limited mariculture propagations.

“…It is essential to consider the substrate and microhabitat among the culture conditions to ameliorate the chances of survival of crab species under laboratory conditions. Crabs attack, kill and eat their species and so the phenomenon of cannibalism is very common among the crabs as reported 11 . Besides this, aggression and cannibalism reduce the survival rate of Scylla sps 12 .…”

The main aim of the present study was to scrutinize the substrate and microhabitat preferred by the Himalayapotamon emphysetum under laboratory conditions. In the first experiment, different substrates: gravel, stones, and cobbles were placed in the round plastic containers, and in the second experiment: grass, aquatic plants, and wood fragments were used as microhabitats for analyzing the preference of the crab species. Minimum mortality was observed when the crabs were provided with the substrate of stones and wood fragments as the microhabitat. The results of the present study provide a better understanding of the breeding and culture of commercially important crab species of Jammu and Kashmir Union Territory and can be used as a reference for determining the culture conditions for Himalaypotamon emphysetum that will boost the economy of this region. The studies related to the preference of habitat and substrate of any species is essential for aquaculture and breeding programs.
