  • Effects of Acadian Marine Plant Extract Powder (AMPEP) and ammonium
           phosphate as nutrient enrichment on the ice-ice disease occurrence and
           growth performance of seaweed Kappaphycus striatus

    • Authors: Albaris TAHILUDDIN; Abdurazis ANDON, Mardrina BURAHİM
      Abstract: Due to the frequent ice-ice disease outbreak and stagnant growth of Kappaphycus species, farmers and researchers have been considering nutrient enrichment as one way of easing these issues to increase production to meet the growing demand for carrageenan in the world market. In this study, we determined the effects of organic and inorganic fertilizers as nutrient enrichment on the ice-ice disease occurrence and growth performance of seaweed Kappaphycus striatus. Three treatments were used in the study: T1 = Acadian Marine Plant Extract Powder (AMPEP) at 0.01 g L-1, T2= ammonium phosphate, 16-20-0 at 8.82 g L-1, and T3 = control. Nutrient-enriched seaweed K. striatus was planted using the fixed-off bottom method for 45 days. Findings revealed that the growth performance of T2 (6.1±0.14 % day-1) was significantly higher (p<0.05) after 30 days compared to T1 (5.56±0.16 % day-1) and control (5.45±0.17 % day-1). In terms of ice-ice occurrence, T1 (0.57±0 %) was significantly lower after 45 days of culture compared to control (59.67±27.32 %) but not significant with T2 (23.22±12.83 %). Our study suggests that organic fertilizer (AMPEP) could effectively reduce the ice-ice disease occurrence, while ammonium phosphate could enhance the growth performance of K. striatus.

  • Growth and Survival Rates and Feed Utilization of Orange-spotted grouper
           Epinephelus coioides Cultured at Different Stocking Densities in Floating
           Net Cage

      Abstract: Epinephelus coioides, commonly known as orange-spotted grouper, has potential aquaculture prospects due to its scarcity in the wild and marketability in semi-tropical and tropical regions. A floating net cage system has been demonstrated to be a technically and commercially feasible method of raising fish, allowing for a much higher stocked density of fish. In this study, orange-spotted grouper (E. coioides) was cultivated in a floating net cage fed with trash fish (Decapterus sp. and Sardinella sp.) to determine the effect of stocking density on survival rate (SR) and specific growth rate (SGR). In addition, feed conversion ratio (FCR) and feed intake (FI) were also investigated. Three stocking densities: 20 fish/m3, 30 fish/m3, and 40 fish/m3, were used in the study. Results showed that E. coioides cultured at a stocking density of 20 fish/m3 in a floating net cage gained the highest SGR and SR significantly (p<0.05). FI was significantly lesser (p<0.05) at a stocking density of 30 fish/m3, while FCR was significantly lower (p<0.05) at a stocking density of 40 fish/m3. Thus, this study suggests that a smaller stocking density of 20 fish/m3 is more effective to be used in the culture of grouper E. coioides in a floating net cage.

  • Antimicrobial Effects of Extracts from Ulva intestinalis (Linnaeus 1753)
           and Sargassum vulgare (F. Furcatum (Kützing) J. Agardh 1889) on Some
           Pathogenic Microorganisms

    • Authors: Büşra PEKSEZER; Mehmet Tahir ALP, Deniz AYAS
      Abstract: Macroalgae have an important place due to their antimicrobial properties. In our study to determine the antimicrobial properties of macroalgae, green algae (Chlorophyta) Ulva intestinalis and brown algae (Phaeophyceae) Sargassum vulgare were used. Macroalgae, gram positive bacteria strains Staphylococcus aureus, Enterococcus faecalis, gram negative bacterial strains Escherichia coli and Klebsiella pneumoniaeosis and yeast parapsilrobial activities against Candida parapsilrobial activities by using acetone, ethanol, chloroform and methanol as extraction, well diffusion and spectrophotometric broth microdilution method in macroalgae. Antimicrobial activity values were determined as Sargassum vulgare (0.35 mm) and Ulva intestinalis (0.23 mm).

  • Biometric Features of marbled spinefoot Siganus rivulatus (Forsskål &
           Niebuhr, 1775) from Mersin Bay (Northeastern Mediterranean), Turkey

    • Authors: Nuray ÇİFTÇİ; Mısra BAKAN, Deniz ERGÜDEN, Deniz AYAS
      Abstract: In the study, it was aimed to determine the morphometric measurements of Siganus rivulatus (Forsskål & Niebuhr, 1775) sampled from Mersin Bay in February 2021. The average value of some morphometric measurements of fish from Mersin Bay (n=196) were found that the total length 17.87 ± 3.11 cm, standard length 13.88 ± 1.96 cm, fork length 17.06 ± 1.35 cm, head length 3.60 ± 0.76 cm, eye diameter 1.08 ± 0.23 cm, interorbital distance 1.60 ± 0.34 cm, body width 2.32 ± 0.48 cm, dorsal fin base length 10.45 ± 2.19 cm, anal fin base length 6.26 ± 1.31 cm, pectoral fin length 2.56 ± 0.53 cm and caudal peduncle height 0.78 ± 0.16 cm. The total length-weight relationship of the species was determined as W = 0.0004xTL4.197 (r2=0.973) and it was found that fish showed positive allometric growth.

  • Ichthyophthirius Multifiliis (Fouget, 1878) Infection in Telescope
           Goldfish (Carassius Auratus) Culture

    • Authors: Cafer KOYUNCU
      Abstract: This study was carried out to determine the cause of sudden death in telescope gold fish (Carassius auratus) raised in an aquarium farm in Mersin between May-July 2021. In order to determine the cause of these sudden deaths, samples were taken from the skin and fin tissues of the fish and it was determined that the cause of death was caused by the parasite Ichthyophthirius multifiliis (Ciliophora: Ichthyophthiriidae). In addition, the morphological features of the parasite and its symptoms in fish were determined.
