Liza Macrolepis

Background: The mullets fish Liza macrolepis and Moolgarda engeli are predominant in the Lambada Lhok waters in Aceh province. At present, no scientific report on this species in Aceh waters is available. Therefore, the objective of the present study is to examine the growth pattern and condition factor of the species of mullets L. macrolepis and M. engeli harvested from the aforementioned coastal waters. Methods: The sampling was done in three locations in the Lambada Lhok waters from July to November 2018. The fish were captured using gillnets from 6:00 AM to 3:00 PM four times a month for five months.  A total of 242 L. macrolepis and 109 M. engeli were used for the analysis. The growth pattern was analyzed using linear allometric model; then, two condition factors, Fulton’s and relative weight, were calculated. Results: The study revealed a b value of 2.49 for the male L. macrolepis and 1.81 for the female. The b value was 3.22 for the male M. engeli and 3.41 for the female. The b value of the fish was higher during the dry season. The Fulton’s condition factor of the male L. macrolepis was 1.19, and that of the female was 1.19. The relative condition factor of this species was 100.11 and 100.01 for males and females, respectively. The Fulton condition factor of male M. engeli was 1.05 and that of the female was 1.06. The relative weight condition factors were 101.08 and 100.61 for the male and female, respectively.   Conclusions: The growth pattern of M. engeli tends to be isometric, whereas that of L. macrolepis has a negative allometric growth pattern. The condition factors indicate that the Lambada Lhok waters are still in good condition and support the growth of the mullets, but M. engeli is more adaptable than L. macrolepis.

Abstract The objective of the present study was to examine the growth pattern and condition factors of the naleh fish, Barbonymus gonionotus Bleeker, 1849 in Nagan River, Nagan Raya District, Aceh Province, Indonesia. The sampling was conducted for 12 months from January 2016 to December 2016 using the explorative survey method. The sampling locations were determined based on the information given by local fishermen. A total of 761 fish samples were collected during the study. The Linear Allometric Model (LAM), Fulton’s and Relative Weight conditions factors were utilized to analyze the length-weight relationship and condition factor of the fish using growth parameters. The results showed that the highest coefficient of b was recorded in December, where the b value of males were 3.82 and 4.23 for the females with the average b value of males and females were 2.92 indicating an isometric growth pattern. The average Fulton’s condition factor (K) was 2.28 and the average Relative weight (Wr) condition factor was 100.59. It is concluded that fish had the isometric growth pattern and based on K and Wr value, the result implies that the waters are still in a good condition. Furthermore, the availability of food sources, low competitors, and low predators indicate that the aquatic environment is in a stable condition.

AbstractThe objective of the present study was to examine the length-weight relationships and condition factors of snapperLutjanus russellii, ponyfishAurigequula fasciataand white-spotted spinefootSiganus canaliculatusharvested from Ulelhee Bay, Banda Aceh City, Indonesia. These species are the predominant fishes caught by traditional beach trawl in Ulelhee Bay, Banda Aceh City, Indonesia. The sampling was conducted for three months from April to June 2015 at one-week interval. A total of 900 fish samples (300 individuals for each species) were measured for the total length and body weight. The length-weight relationships were calculated using Linear Allometric Model (LAM), while the relative weights (Wr) and Fulton’s condition (K) factors were calculated to assess the condition of the fish samples. The results showed that thebvalue of 3.04 in snapper indicates isometric growth pattern, while ponyfish and white-spotted spinefoot fish had the b values of 1.41 and 1.75, respectively, and these species display an allometric growth pattern. The average Fulton’s condition factor (K) of snapper was 3.01 for male and 2.49 for female; female ponyfish has the K value of 2.92 and 2.92 for male. In addition, the average K value of white-spotted spinefoot was 2.61 and 2.59 for female and male, respectively. The relative weight condition factor ranges from 58.73 to 166.09 for snapper, from 70.55 to 129.65 for ponyfish, and from 71.63 to 133.53 for white-spotted spinefoot. In general, the relative weight condition factors tendedto be 100. It is concluded that snapper has isometric growth pattern, while ponyfish and white-spotted spinefoot display the negative allometric growth pattern. The condition factors are in excellent condition and indicate a balance of prey and predator.

Abstract: Aim In this paper we present a scientometric analysis aimed at to assess and quantify the contribution of Le Cren’s condition factor and the main ideas advanced by ‘Le Cren, 1951’ to studies on the health of individuals or populations in aquatic environments. Specifically, we addressed the following questions: (i) what are the temporal and spatial citation trends of ‘Le Cren, 1951’?; (ii) Which journals cited ‘Le Cren, 1951’ most frequently?; (iii) In which types of aquatic environments and organisms have Le Cren’s condition factor been most commonly applied?; (iv) Which of the main applications addressed in ‘Le Cren, 1951’ have been most frequently used by fisheries scientists?; (v) Which of the methods (i.e., Quételet’s index or body mass index, Fulton’s condition factor, Le Cren’s condition factor, relative weight, residual index and scaled mass index) used to estimate condition factor identified in the papers that cited ‘Le Cren, 1951’ have been most frequently used? In addition, the main criticisms of the use of the relative condition factor are discussed. Methods We carried out a scientometric analysis on the papers published from 1951 to December 2015 that cited Le Cren’s article. The papers were obtained from the Thomson Reuters database (ISI Web of Knowledge, apps.isiknowledge.com) in May 2016. Results In total, 1128 papers were assessed. The number of citations increased significantly over time. Most citations occurred in two journals (Journal of Fish Biology and Journal of Applied Ichthyology). Most of papers were carried out in marine environments. In addition, we show that Le Cren's paper has been cited mainly in articles that estimate the condition factor or the weight-length relationship of populations. Finally, we emphasize that the relative condition factor proposed by Le Cren in 1951 is still the main method used to estimate the body condition of an individual or population. Conclusions Le Cren's significant contribution to animal well-being is undeniable, and we emphasize that among the methods identified in the papers that cited ‘Le Cren, 1951’ that estimated body condition, the relative condition factor proposed by Le Cren in 1951 is still the most commonly used method.
