macrolepis had negative allometric increases activities. But not, this new b worth of this new ladies is actually less than that of the male. The brand new b property value a man Yards. engeli showed a confident allometric growth trend. Centered on such development development analysis, the analysis revealed that M. engeli increases a lot better than L. macrolepis, thereby appearing you to definitely Yards. engeli is more functional on environmental reputation out of Lambada Lhok oceans. In addition, the field observation towards the connect composition of your anglers exhibited that Yards. engeli has also been prevalent. The fresh new Fulton’s reputation grounds shown hook difference between K worthy of between the men and women for variety, where in fact the K worth try higher than step one. Based on Morton and you may Routledge thirty-six , a fish populace is actually good condition in the event the K well worth exceeds step one. The research indicated that the brand new K property value L. macrolepis varied in one.16 to 1.22, and you will step one.03 to a single.09 having Meters. engeli; for this reason, each other populations have been in good condition, when you look at the deceased and you may wet season, respectively. As well, this new relative weight reputation foundation away from one another species is nearly 100, showing an equilibrium ranging from victim and you may predator 20 . This type of efficiency demonstrate that these seas give an acceptable food resource of these kinds. The new relative lbs standing factor along with represents fish health conditions, stock rates, and you may administration account 23,thirty-five,thirty-six,38,39 . Therefore, the Lambada Lhok waters bring adequate dining present to have mullets.
The results including exhibited variations in growth patterns in deceased and you can damp 12 months, which brand new fish expanded best when you look at the dry season. The newest likely reason is the fact that the waters are clear and you will an effective restriction rates regarding sunrays penetrates into seas, causing the organization out of phytoplankton and you will algae. Alga was a primary food on the mullets forty–43 . By comparison, turbidity and you can currents was high from inside the wet season forty two , and and therefore think so you’re able to prevent the development of phytoplankton and algae as important meal to possess mullets 42,45 . An identical event is actually said of the Chu ainsi que al. 29 , just who receive a poor gains pattern in L. macrolepis inside the Taiwan throughout winter, and you will an enthusiastic isometric progress pattern in the summertime and you will spring. Additionally, Sandhya and you will Shameem 30 observed an awful progress pattern from inside the L. macrolepis inside polluted seas, weighed against an isometric increases trend within the unpolluted oceans. However, a face-to-face trying to find is said for the five species of seafood (Barbus intermedius, Clarias gariepinus, Labeo cylindricus, Oreochromis niloticus baringoensis and Protopterus aethiopicu) about Lake Baringo, Kenya 46 in which this type of variety was increasing really during wet-season 46 . Hence, they determined that seasons inspired rather towards the LWRs, however, failed to change the position foundation away from seafood 46 . A terrible growth trend was also stated from inside the three types of mullets (Parachelon grandisquamis, Neochelon falcipinnis and you can Mugil cephalus) on Sombreior Lake, Niger Delta, Nigeria 47 . According to Blackwell mais aussi al. 20 the fresh new Wr is right so you’re able to estimate fish health conditions, stock, and government degrees of fisheries information.
According Muchlisin ainsi que al. twenty-two , in addition to struggling with environmentally friendly situations, the growth trend away from fish is additionally influenced by fish choices; such as, the fish that have been energetic swimmer had a lower b well worth compared to those which were passive swimmers forty-eight–fifty .
The average relationship coefficients regarding L. macrolepis had been 0.93 and you may 0.89 in females and you may guys, respectively, while M. engeli had a relationship coefficient from 0.89 for men and you can 0.93 for ladies. Overall, the brand new correlation coefficients out-of L. macrolepis and you can M. engeli were equivalent (over 75%), proving a strong correlation anywhere between full size and body lbs. The fresh new dedication coefficients off L. macrolepis was indeed 0.85 and you can 0.65 towards the men and women seafood, correspondingly, for example whenever 65%–85% off overall variants should be said of the design, when you find yourself Meters. engeli had a property value 0.90 and you will 0.94 for men and you will lady, respectively, appearing you to 90%–94% off alternatives might be said by the design.
