“…In our results, T4 treatment groups showed the higher Crude protein (28.66±0.24%) as compared to other treatments by comparing with [27]. These results also evidenced that dietry protein level in the fish body can be enahnced by increasing protein level of aquafeed [17, 31, 32]. Aquafeed with highest lipid content showed the most elevated crude lipids in the fish body [33].…”

The objective of the research was to find the effects of numerous traditional and commercial aqua feed on proximate composition and growth performance of Grass carp (Ctenopharyngodon idella) reared in the semi intensive composite culture system. The aqua feeds of various companies (AMG, Supreme, Aqua, Star Floating, Hi-Pro and Punjab feed) used as commercial feed. Farm made feeds were Maize gluten and Rice polish. For confidentiality, these feeds were randomly assign code T1, T2, T3, T4, T5, T6, T7 and T8 which were only known to investigating staffs. There were two replicates for each treatment. In this research, significantly maximum growth was recorded in T3 as compared to other treatments. Lesser weight gain was observed in the T1 (270.30±60.5). The maximum body length (19.25±2.19) was found in T3. Similarly, the minimum body length (5.97±2.94) was seen in T2. FCR ratio (2.36±0.01) was recorded in T3. Simultaneously, FCR (1.86±0.002) was also recorded in T4 that is the perfect ratio for fish farmers. Higher SGR was found in T3 (1.62±0.05). Overall, T4 showed lesser SGR (1.05±0.001). T4 showed the higher Crude protein (28.66±0.24%). T3 showed more fat content level (5.46±0.33%) in the body. These outcomes also supported that enrichment in the dietary amount of protein and lipid level improve lipids content and crude protein in fish body weight. Thus, based on growth performance, survival and proximate composition, it is concluded that T3 & T4 may be recommended for commercial culture of Ctenopharyngodon idella.

“…Fish have long held a pivotal role as a crucial source of human nutrition as a source of essential nutrients and a significant role in feeding the world's growing population (Abidin et al, 2022). Healthy fish populations lead to healthy oceans, and it is our responsibility to be a part of the solution (Abdel- Ghaffar et al, 2008;Hussain et al, 2021;Khalid et al, 2021;Hassan et al, 2021Hassan et al, , 2022a. The Arabian Sea of Pakistan is one of the most identical Sea worldwide and has diverse fish fauna (≈1,000 species) due to nutrient-rich waters (Hassan et al, 2022b).…”

Diseases in fish due to helminth parasites, especially Philometra species, are the primary worry in aquaculture. Philometra are responsible for health problem in fishes they directly affect fish growth and population parameters. A comprehensive survey was conducted involving the examination of the marine fish species Terapon jarbua, gathered from the coastal waters of Sindh, Pakistan In this research different Philometra species from marine fish Terapon jarbua during 2021 and 2022. Philometra nematodes, belonging to the family Philometridae, are common parasitic organisms inhabiting both marine and freshwater environments. Their prevalence, particularly when existing in high numbers within host organisms, can lead to severe and potentially lethal consequences. Employing light microscopy techniques, diverse species of Philometra were identified, including Philometra teraponi, P. jarbuai, P. arabiai, P. karachii, and P. awarii, localized primarily within the ovaries of the host fish. A total of 140 fish samples were examined and 76 were infected. The intensity of infected fish was 54.28%. The identification process encompassed meticulous analysis of crucial parameters, such as body size, esophagus length, positioning of the nerve ring, dimensions of the ventriculus, and ligament size. Intriguingly, the parasites were found in varying contexts; while some were free within the ovaries, others were embedded within tissues, inducing severe muscular dystrophy. This research presents novel findings of Philometra nematodes in the marine waters of Pakistan, extending their host and geographical distribution records. Future studies are needed to better evaluate and describe the dynamics and the epidemiology of Philometra infection in wild and cultured fish species

“…Increased dietary protein has often been associated with higher growth rates because protein provides essential amino acids for protein synthesis (Hassan et al, 2022). Thus, in fish fed lower levels of protein, the mobilization of body protein must be higher to meet nutrient demands for protein synthesis, maintenance, and metabolism, while excessive protein in the diet is catabolized or deaminated and excreted (Yan et al, 2019;Sivaramakrishnan et al, 2022).…”

Digestible protein levels and metabolic responses in juvenile piapara (Megaleporinus obtusidens)

et al. 2023

The piapara (Megaleporinus obtusidens) is an omnivorous fish with great market potential. However, little is known about its dietary requirements. This study aimed to determine the effects of dietary protein on growth and physiological indicators in piapara. Three hundred piapara juveniles (24.0 ± 1.3 g) were distributed in 20 tanks of 130-L (15 fish/tank) provided with continuous aeration and water. Five isoenergetic diets (14.0 MJ/kg) were formulated to contain increasing levels of digestible protein (21, 24, 27, 30, and 33% DP). After 77 days, weight gain and ammonia concentration in water were found to increase linearly with increasing digestible protein (DP) level (p<0.05). Protein productive value (PPV) reached a maximum at 28.4% DP. No relationship was found between DP level and serum ammonia, liver alanine aminotransferase (ALT) activity, hepatosomatic index (HSI), liver glycogen (GL) or liver lipid (LL) content (p>0.05). Mesenteric fat index (MFI) and liver malic enzyme (ME) activity followed a quadratic pattern (p<0.05) and reached a maximum at 25.8% and 27.1% DP, respectively. Muscle lipid (ML) content decreased linearly with increasing DP level (p<0.05), whereas liver glucose-6-phosphate dehydrogenase (G6PD) activity decreased linearly as DP level increased (p<0.05). Results showed that a diet containing 28.4% PD provides better crude protein retention efficiency and reduces amino acid deamination in M. obtusidens. Low protein diets increased energy retention efficiency, whereas fish fed high protein diets had higher ammonia excretion.
