With this regard, the growth performance, e.g., final weight, specific growth rate (SGR), and cannibalism rate of Persian sturgeon were assessed. The study was performed using two separate strategies; size heterogeneity and feeding/fasting strategy (experiment-A), besides implementing stocking density (experiment-B). In the experiment-A, twelve circular tanks (9.6 L) were considered as following: A₁ (5 large starved fish +5 small starved fish); A₂ (5 large fed fish +5 small fed fish); A₃ (all 10 large starved fish); A₄ (all 10 large fed fish); A₅ (all 10 small starved fish) and A₆ (all 10 small fed fish). In experiment-B, the stocking density was doubled for all groups in the same tanks: B₁ (10 large starved fish +10 small starved fish); B₂ (10 large fed fish +10 small fed fish); B₃ (all 20 large starved fish); B₄ (all 20 large fed fish); B₅ (all 20 small starved fish) and B₆ (all 20 small fed fish). Data were collected at the end of the 7th and 14th days. Growth performance increased significantly in all fed treatments of experiment-B in comparison to starved treatments (<i>P</i> &lt; 0.05). The highest final weight and SGR was observed in B₂ (363.5 ± 130.1 mg in 14th day) and B₆ (26.5 ± 1.0% day⁻¹ in 7th day), respectively. Cannibalism rate was increased in Persian sturgeon larvae maintained at low density, in which the highest rate was observed in the starved groups (A₁ [27.5%], A₃ [35.0%], A₅ [40.0%]). Size heterogeneity leads to disappear/die all small larvae, in both low- and high-density only in the starved group, regardless of size, died at the end of the second week. In conclusion, in Persian sturgeon, cannibalistic behavior is more affected by stocking density. To manage larviculture of this species, optimizing the stocking density to prevent the cannibalistic interaction, besides having continuous feeding is a paramount.</p>","PeriodicalId":14894,"journal":{"name":"Journal of Applied Ichthyology","volume":"38 5","pages":"487-492"},"PeriodicalIF":0.9,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48289233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each of the leaf meals was included at 10 g 100 g⁻¹ in five dietary treatments. As a control, a diet with no leaf meal was used. Each diet was randomly allocated to three tanks and the hybrid fish were also randomly stocked in 60 L glass tanks at 15 fish per tank. When compared to the control group, the leaf meal-treated groups performed better in terms of growth, which was significantly (<i>p</i> &lt; .05) higher with Ipomea- and Napier-fed groups. Ipomea-fed fish had the best performance among the leaf meal groups. The leaf meal-based groups had numerically greater haematological profiles than the control fish but shared statistical similarities (<i>p</i> &gt; .05) with the control group.

Shortnose sturgeon (<i>Acipenser brevirostrum</i>) is an endangered species (USA) and a species of special concern (Canada) that live on the eastern coast of North America. Although previous studies have focused on the acute critical thermal maximum (CT_max) of shortnose sturgeon, nothing is known with respect to their acute critical thermal minimum (CT_min) and the overall thermal tolerance of this species. This study examined the upper (CT_max) and lower (CT_min) thermal tolerance of shortnose sturgeon acclimated to 12 and 18°C. CT_max increased with increasing acclimation temperature; however, there was no significant relationship between acclimation temperature and CT_min.
