“…It has been successfully applied towards various stressors, including pCO 2 (Gräns et al, 2016). Elevated cortisol and increased plasma glucose indicate that the fish are in stress (Bertotto et al, 2010; De et al, 2019). The results in the current research showed a significant reaction towards the health assessment (haematological parameters, cortisol and glucose) of the high pCO 2 exposed fish.…”

Increased acidification has shown to bring negative impacts on marine fish. Currently, fish with scales have been extensively investigated, whereas a few systematic studies have been carried out for investigating impacts of acidified environment towards the growth of scaleless fish. Thus, this research aimed to evaluate carbon dioxide, CO2‐induced acidification impacts towards the welfare (growth with health) of the commercially aquaculture scaleless fish, Sagor catfish (Hexanematichthys sagor) for 20 weeks. Fish specimens were exposed to control pCO2 (400 µatm), mild pCO2 (550 µatm) and high pCO2 (900 µatm). Growth were measured by feed conversion ratio (FCR) plus specific growth rate (SGR). The outcomes indicated that the significantly lowest SGR was flaunted in high pCO2 group supported with the significantly highest FCR indicating poor growth. Health parameters significantly showed the highest value of red blood cell, haematocrit, haemoglobin, white blood cell, thrombocyte, mean corpuscular volume and haemoglobin in control group while urea, cholesterol, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, serum cortisol plus glucose were significantly the lowest in control pCO2 with regard to mild and high pCO2 group. These findings can serve as important baseline data in formulating managements regarding the specific effects of acidification on scaleless fish.

“…Therefore, grouper seed nursery in a floating net cage (FNC) at sea is required as closed as possible to the growing-out production location unit. A nursery system at sea frequently faces several obstacles, such as high oceanographic dynamics and water quality compared to the nursery system on land which causes the cultured fish to be more potentially stressful and exposed to diseases (Hadiroseyani et al, 2010;Palm et al, 2011;Effendi et al, 2016;Dahlia et al, 2019;De et al, 2019). The economical impact of disease outbreaks is extremely significant as decreasing the grouper survival rate at 50-70% (Rimmer & Glamuzina, 2019).…”

Untuk mendukung usaha budidaya ikan kerapu kini tengah digalakkan sistem pendederan intensif dalam keramba jaring apung (KJA) di laut. Salah satu cara untuk menjaga kondisi ikan tetap sehat dalam sistem tersebut yaitu dengan pemberian fitofarmaka seperti meniran-bawang putih. Tujuan penelitian ini adalah untuk mengevaluasi penambahan tepung meniran-bawang putih melalui pakan terhadap status kesehatan dan kinerja produksi benih ikan kerapu cantang pada pendederan dalam keramba jaring apung di laut. Benih ikan kerapu cantang (panjang 8.27 ± 0.16 cm dan bobot 10.89 ± 0.83 g) dipelihara dalam KJA berupa waring 1x1x1.5 m3 dan diberi pakan dengan penambahan tepung meniran-bawang putih 20 + 25 g/kg pakan selama 7 hari dan 14 hari pertama pemeliharaan, serta tanpa tepung meniran-bawang putih (kontrol) sebagai perlakuan. Ikan dipelihara selama 42 hari dan disampling setiap 2 minggu untuk diambil darah serta diukur bobot dan panjangnya. Penambahan tepung meniran-bawang putih selama 14 hari pada pakan ikan kerapu dapat meningkatkan status kesehatan dan kinerja produksi. Kata kunci: ikan kerapu cantang, kinerja produksi, meniran-bawang putih, status kesehatan.

“…Water temperature and sex can greatly influence fish haematological parameters, especially for poikilotherms (Angilletta et al, 2002; Costas et al, 2012). Changes in acclimation temperature can affect fish's erythrocyte parameters (Ahmed et al, 2020), reduces oxygen carrying capacity and exacerbates fish oxygen demand (De et al, 2019; Islam et al, 2020). Similarly, water temperature affects leucocyte distribution, and cellular membrane phospholipid rigidity (Avtalion & Clem, 1981; Bly et al, 1986; Bly & Clem, 1992; De et al, 2019).…”

This study assessed the selected peripheral blood haematological parameters and metabolite profiles linked to liver, serum and muscle samples in 3‐year‐old male (weight = 131.19 ± 29.24 g; total length = 21.33 ± 1.20 cm; n = 5) and female (122.96 ± 27.04 g; total length = 21.09 ± 1.09 cm; n = 5) giant kokopu (Galaxias argenteus) broodstock cultured at 12°C and 16°C. Temperature and sex did not influence haematocrit values or counts of total blood cells, erythrocytes and leucocytes. However, fish reared at 16°C had higher thrombocyte counts, whereas those kept at 12°C exhibited the highest proportion of lymphocytes. At the metabolic level, sex was the main factor that influenced metabolite levels across tissues, with particularly higher amino acid metabolites in liver of females. Changes linked to the interaction between temperature and sex showed significant differences in fatty acid profiles of liver, and in amino acids in muscle and serum samples. Males kept at 16°C exhibited decreased levels of myristic acid and nonadecanoic acid linked to homeoviscous adaptation. In females, levels for energy metabolites including tyrosine and aspartic acid (in muscle), and alanine (in serum) were disturbed at 16°C. The study provides insights into preliminary haematological and metabolic effects associated with sex and temperature in galaxiids.
