The information and knowledge have been displayed since the tables and you can figures, https://datingranking.net/bhm-dating/ and therefore the research was in fact assessed descriptively as a consequence of testing which have related account, theories, and you can profession observations.
Length-lbs dating
The field observation of your own catch composition showed that Liza macrolepis and Moolgarda engeli were widespread. A maximum of 242 L. macrolepis and 109 Meters. engeli were tested and measured regarding the investigation. The length of male L. macrolepis varied away from 141.cuatro – 202.1 mm (164.8 ± mm), and you can varied out-of 129.2–185.4 mm (159.step 1 ± mm) for females. The human body weight from men L. macrolepis ranged off 34.7 g so you can 89.6 g (54.1 ± 13.step three grams during the mediocre), and you may twenty-eight.8 grams in order to grams (47.9 ± nine.52 g in the average) in females. Along the male M. engeli varied from 109.9–188.5 mm (161.9± mm) and you may 116.5–182.step three mm (154.step one ± mm) for females. One’s body weight of one’s men is 13.six – 108.5 gram (47.6±19.3 gram), and that of one’s female is actually fourteen.2–75.1 gram (41.cuatro ± gram). Brutal investigation arrive once the fundamental investigation 37 .
The outcomes of your LWRs studies into L. macrolepis showed that a man fish had a-b worth of dos.forty two with a relationship coefficient from 0.93, and lady seafood got a b value of step 1.81 and you may a correlation coefficient off 0.82 (Figure 2a and you will 2b). Therefore, a man and females L. macrolepis presented bad gains activities, and you will a method correlation ranging from fat and you may overall period of the seafood. The results away from LWRs research out of men M. engeli indicated that the typical b worthy of is step three.twenty-two with a beneficial coefficient relationship off 0.89. The feminine M. engeli got an average b worth of 3.41 having an effective coefficient relationship regarding 0.93 (Profile 3a and you may 3b). These data indicate that a man and females M. engeli provides a positive allometric development trend, and you will an effective correlation between body weight and you will complete length.
Profile dos.
The length-lbs relationships regarding Liza macrolepis predicated on linear allometric model (a) male, (b) female; Assessment away from noticed and forecast increases having men (c), and you can female (d) of Liza macrolepis. R2 – commitment coefficient, r – correlation coefficient, N – number of seafood sampled.
Shape 3.
The length-pounds relationship out-of Moolgarda engeli centered on linear allometric design (a) male, (b) female; Review from seen and predicted increases to have men (c), and women (d) from Moolgarda engeli. R2 – determination coefficient, roentgen – relationship coefficient, N – number of seafood sampled.
Centered on testing year, the average b value of L. macrolepis (male and female) is actually 2.78 during the dry year and dos.twenty eight during the wet-season (Contour 4a). This new b property value Meters. engeli are step three.42 during the inactive season and you may dos.forty-eight inside wet season (Contour 4b). This type of studies signify brand new b worthy of is lower from inside the wet season for both types. The newest scatter plots of land off predicted practical lbs to own respective observed size, given that determined throughout the ingredient of duration–weight regression, try presented when you look at the Profile 2c and you can 2d and you can Profile 3c and you can d. The latest regression designs inform you an improvement between the seen and you may predict progress activities both in kinds.

The length-lbs dating off Liza macrolepis (a) during the dead 12 months (b) throughout wet-season and you will Moolgarda engeli (c) throughout inactive season (d) through the wet season. R2 – determination coefficient, r – correlation coefficient, N – quantity of fish tested.
Status activities. The outcomes indicated that the male L. macrolepis got an excellent Fulton’s condition (K) basis of just one.19, and you may relative weight status basis (Wr) away from ; once the females got an effective Fulton’s reputation basis of just one.19, and you may relative pounds status grounds off . While doing so, male Yards. engeli had an effective Fulton’s updates basis of 1.05, and relative weight condition foundation away from ; while this new lady has actually Fulton’s condition grounds of just one.06, and you can cousin pounds reputation basis out-of (Desk 1). Considering sampling seasons, the Fulton’s standing off L. macrolepis inside dry season are step 1.twenty two and for the cousin weight; during the wet season these were 1.19 and you may , respectively. Concurrently, the brand new K and you may Wr opinions off Meters. engeli inside the dry season was in fact 1.03 and you may , respectively; within the wet season these people were step one.09 and you may , correspondingly (Dining table 2). The content of conditions were observed visually. The occasions are typically wet throughout the testing in the wet-season, and therefore the turbidity is highest during this year.
