Fresh water shortage is indeed a global issue that affects many areas of the world, including desert regions like the Thar Desert of Pakistan. Recurring droughts have badly affected the marginal communities of these areas. The desert has wide spread lenses of saline groundwater. There is a pressing need for exploring ways to use saline groundwater and identifying alternative sources of livelihood under the prevailing conditions. Therefore, a research study on saline aquaculture was conducted. Twenty fish fingerlings (40-50 g) of the varieties namely rahu labeo (locally kurh’rho), silver carp, mrigal carp (morakhi) and grass carp were stocked into the earthen fish pond. Saline groundwater having electrical conductivity (EC) between 8.5 - 9.0 dS/m was used to fill the pond. The overall yield of silver carp was the highest (1275 g/fish) followed by grass (1093 g/fish), mrigal carp (965 g/fish) and rahu labeo (610 g/fish). However, meal yield of grass variety was the highest followed by mrigal carp, silver and lowest of rahu labeo. Silver carp varieties had 330 g/fish of egg in their bodies. Hence, for the massive fingerling development, silver carp is recommended for saline aquaculture. However, for meal production and high economic return, grass carp should be selected for saline aqua-culturing.

This study investigated the effects of three supplemental diets varying in protein percentage (T1- 28%, T2- 30%, and T3- 32%) on the fillet composition of Rohu (Labeo rohita), Catla (Catla catla), Mrigal (Cirrhinus cirrhosus), and Silver Carp (Hypophthalmichthys molitrix) reared in ponds with supplemental diets. The control treatment with no supplemental feeding was also included to conduct the experiment. Fish from control ponds had substantially lower mean muscle protein concentrations than fish from ponds that received supplemental feeding, with 28% and 30% protein diets producing the most muscle protein. Compared to other treatments, fish fed a diet containing 32% protein had significantly (p<0.05) higher muscle lipid concentrations (2.22%). The muscle carbohydrates were greater in fish from ponds fed 28% protein diets. The Rohu (L. rohita) had the highest percent of muscle protein among the three sampled fish species, while Silver carp (H. molitrix) had the lowest, with all other species having intermediate values. The Mrigal (C. cirrhosus) and Silver Carp (H. molitrix) had the highest carbohydrate in their muscles, while Rohu (L. rohita) had the least carbohydrate content. During polyculture of cyprinids in ponds, the supplemental feeding of diets with protein ranging from 28 to 30% protein can be recommended as an optimal protein diet to attain the higher growth performance of carps avoiding the wastage of feed at the farmer’s level in semi-intensive polyculture farming.

There are many species of Poeciliidae fish in nature. Poeciliidae is a family of freshwater fish in the order Cyprinodontiformes and are well-known aquarium fish, such as guppies, mollies, platies and swordtails. Therefore, genetic analysis on Poeciliidae is important to collect information about biodiversity, genetic classification, and study developments that occurred during evolution. One approach to determine genetic diversity in many fish species can use Random Amplification Polymorphic DNA (RAPD). This study aims to analyze the genetic diversity of Poeciliidae fish using the RAPD-PCR method. This research was conducted at the Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Indonesia. The samples used were guppy fish (1), platy (2), molly (3), swordtail (4), and goldfish (5). RAPD-PCR was performed using OPA-6 primer. Procedures include sampling, isolation or extraction of DNA, DNA amplification using the RAPD technique, electrophoresis, and data analysis using NTSys. Genetic diversity of Poecillidae can be analyzed using RAPD-PCR. The phylogenetics of the Poeciliidae fish samples analyzed using OPA-6 showed that the guppy fish species (sample 1) are closely related to the platy fish (fish sample 2). Furthermore, the clade branched out with sample 3 (molly fish), and the three samples are related to sample 4 (swordtail fish).

The study was conducted using two replicate (Batch A and B) for 96 hours under controlled laboratory conditions, with five different concentrations of the extract ranging from 0 to 40 mg/l. The results of the study revealed that the extract had a concentration-dependent toxic effect on the test organisms, with induced behavioural changes such as abnormal and uncoordinated swimming movement, restlessness, respiratory difficulties, and attempts at jumping out. The alterations of physico-chemical parameters of the test water were also observed, indicating the adverse effects of the extract on the aquatic environment. The 96 hours LC50 for Oreochromis niloticus was determine to be 22.124 mg/l representing a log-transformed concentration of 1.345 mg/l. This is the concentration where 50% of the test organisms is expected to die at the end of the 96 hours’ bioassay. The histopathological examination of the gills revealed pathological changes in the test organisms at concentrations of 20, 30, and 40 mg/l whereas no histomorphological changes was observed at 0 and 10 mg/l concentrations of the extract. The result of the present findings suggests that ethanolic extract of P. capitata had severe impacts on the test organisms resulting in mortality and gill damage.

The saddleback deformity, an abnormality of the dorsal fin and profile, lacking one to all of the dorsal spines, accompanied by shape, number and position abnormalities of associated pterygiophores, has been reported in teleosts under culture conditions and in the wild in many locations throughout the world, including North and South America, Asia, Australia, Europe, India and the Middle East. A unique global hotspot for saddleback deformities in wild teleosts is the southeast Queensland Australia coastal region between 26° S and 28° S. At this location the incidence of saddleback has been relatively stable but very high at about 10% of individual teleosts taken in the associated fishery since 1997. Opinions on causation have focused on two possibilities, a developmental defect associated with water pollution or a physical injury. The range of skeletal deformities is vastly different in cultured teleosts compared with those occurring in the wild. There is now mounting evidence that physical injury is causing saddleback in teleosts in southeast Queensland Australia. Such injury could be caused by predatory behaviour of piscivorous fish or birds, parasites, or escapement or release from fishing nets and other fishing gear. Population mortality rates associated with saddleback in southeast Queensland are unknown, but expected to be high. The high level of occurrence of saddleback in teleosts in southeast Queensland Australia together with the good understanding of their fisheries biology (age and growth rates, reproductive biology, habitat dependence) and stock assessments of the associated fisheries provide excellent opportunities for further research which would add to the scientific understanding of the saddleback deformity in teleosts throughout the world. A recommendation from this review is that support should be sought by research providers (universities and Government research agencies) from routine annual funding offers from the Australian and Queensland Governments to achieve an increase in the scientific understanding of the saddleback deformity.

Feeding regime or feeding rate? is how much to feed the fish. From how much or portion used for fish feed can affect fish growth. Feeding regime is the determination of the amount of feed per day based on the feeding rate (FR). Feeding rate is the feed requirement per day based on fish biomass and weight. Aims: This research aims to find out how the relationship between feeding regime and fish growth and development. Study Design: Journal review. Methodology: The research method used was descriptive analysis method or library research by collecting data from written sources, namely journals that are relevant to the topic of the writing being carried out. After the data was collected, the next was the data selection in accordance with the research objectives. The selected data was then processed systematically and structured while data analysis was carried out using a descriptive approach by presenting the data obtained in narrative form. Results: The result of this research indicated that fish growth and development are influenced by internal and external factors, one of which is the fish feeding regime. Conclusion: Feeding regime is an important factor in aquaculture. This feeding regime includes how to feed and the portion that will be given to the fish being cultured. Good feed contains sufficient nutrients as needed for fish growth. In addition to the feed factor, growth is also influenced by internal and external factors such as the type of fish, type of feed, environment and others. A good feeding regime or rate? must be adjusted to the nutritional needs of fish, each type of fish has different nutritional needs.

Nutrition is the major crucial factor determining the potential of cultured fish. The increased in costs and formulation quality of fish feed have given reason to the need to increase research for substitutes. Therefore, the fish feeds require to be enriched with additives. The use of synthetic feed additives in the form of antibiotics is currently prohibited because it often causes negative effects and has an expensive price, so an alternative to synthetic feed additives is needed, including from the rhizome group such as turmeric. Aims: This article review aims to collect and provide information about some research results regarding the use of turmeric as a feed additive in fish feed. Study Desgn: Lierature review. The data collection method is carried out by literature study. The data was obtained by searching the literature related to the use of turmeric extract in fish farming activities through search sites on internet media published in the last twenty-three years (2000-2023). The literature used in this article review is obtained from internet media with the keywords "Turmeric", "Turmeric Flour", "Turmeric Extract", "Fish Feed", "Fish Farming", "Feed Additive”. Results: The addition of turmeric (turmeric flour, turmeric extract, and turmeric juice) to fish feed can have a significant effect on growth, feed conversion ratio, feed utilization efficiency, gonad development, survival, and digestive enzymes. Feed additives are added to fish feed in small quantities, but their presence is needed for special functions such as antioxidants or antimicrobials in increasing the growth and efficiency of fish feed. The addition of doses to turmeric varies greatly, as turmeric flour ranges 2-60 ml/kg of feed. This is influenced by the variety and type of fish, feed quality, and aquaculture environmental conditions.So it requires further research to determine the use of the right dose to obtain maximum results.

Dormitator lebretonis (Eleotridae: Steindachner, 1870) is a fish species that inhabits West African coastal environments from Senegal to Angola where this squeaker appears to be an important component of the artisanal fisheries. In particular, this eleotrid is widespread in Benin coastal waters including wetlands, and is intensively exploited for food. The current rearing experiment aimed to determine the salinity levels that favor the survival and growth factors of this squeaker. Six (6) treatments corresponding to six (6) salinity levels (0‰, 5‰, 10‰, 15‰, 20‰, 25‰) and three replicates with 15 individuals of D. lebretonis per replicate were considered for the experiment. Appropriate salinity levels were obtained from a mixture of sea water and fresh water. Overall, within each six (6) treatments, physicochemical features showed insignificant (P>0.05) variations. Regardless of rearing water salinity (0‰ - 25‰), D. lebretonis displayed high survivals ranging between 86.66% (salinity: 0‰) and 100% (salinity: 5‰ - 20‰). Percent weight gained (PWG: 7.94±0.01% - 14.39±0.02%) were moderate and significantly (P<0.05) varied with treatments. Also, significant (P<0.05) variations in the condition factors (K) were recorded, with means ranging between 1.68±0.04 and 1.92±0.01. Nevertheless, specific growth rates (SGR) did not show any significant (F5,18=0.328; P=0.890) variations across treatments. These findings could serve as reference data for an extensive aquacultural valorization of D. lebretonis in numerous Benin coastal wetlands and swamps.

Six (6) treatments corresponding to six (6) salinity levels (0‰, 5‰, 10‰, 15‰, 20‰, 25‰) and three replicates with 15 individuals of D. lebretonis per replicate were considered for the experiment. Appropriate salinity levels were obtained from a mixture of sea water and fresh water. Overall, within each six (6) treatments, physicochemical features showed insignificant (P>0.05) variations. Regardless of rearing water salinity (0‰ - 25‰), D. lebretonis displayed high survivals ranging between 86.66% (salinity: 0‰) and 100% (salinity: 5‰ - 20‰). Percent weight gained (PWG: 7.94±0.01% - 14.39±0.02%) were moderate and significantly (P<0.05) varied with treatments. Also, significant (P<0.05) variations in the condition factors (K) were recorded, with means ranging between 1.68±0.04 and 1.92±0.01. Nevertheless, specific growth rates (SGR) did not show any significant (F5,18=0.328; P=0.890) variations across treatments. These findings could serve as reference data for an extensive aquacultural valorization of D. lebretonis in numerous Benin coastal wetlands and swamps.","PeriodicalId":168203,"journal":{"name":"Asian Journal of Fisheries and Aquatic Research","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125534925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to provide information that the content of flavonoids in Lemna sp. can be an effort to control disease in fish. The research method used is a quantitative descriptive method. The conclusion of the research is to show the ability of Lemna sp. can be used in the prevention of disease in fish. Lemna sp. has immune-modulatory properties, namely the ability to increase phagocytosis so that it can increase the body's immunity in fish. Flavonoid content in Lemna sp. has antioxidant, anti-inflammatory, antimutagenic, and anticarcinogenic properties coupled with their capacity to modulate cellular enzyme function. Flavonoids also have the potential to stimulate the immune system.

The social mapping is intended to map social characteristics, as well as to analyze the driving and inhibiting factors of the fishing community in Cangkol Village, using a survey method with a questionnaire and analyzed descriptively. The research was conducted in April–June 2023. The fishing community of Kampung Cangkol is a community with the majority of middle-aged individuals graduating from elementary school, Muslim, with Cirebonese ethnicity who still preserve local traditions and wisdom. Fishermen's wives have a double role as being in charge of domestic affairs and helping fishermen earn a living. There is a patron-client relationship between fishermen and middlemen as the main access to capital in the fishing business. The upper layer in the fishing community of Cangkol Village is community leaders, the middle layer is skipper fishermen, and the lower layer is the Ship's Crew (ABK). The fishing community in Cangkol Village are fishermen with a traditional fishing unit. The driving factors in the fishing effort of the Cangkol Village fishing community are the preservation of cultural manifestations in the community, the fishermen's wives' dual roles, kinship, and social organizations. The inhibiting factors in the fishing business are weather, age structure, level of education, the existence of middlemen, and the use of technology that is still traditional.
