Weve had two incidents with New England predators. The first a hawk was able to get two of our chicks by the neck through the edge whilst they were feeding and kill them. Our solution to this is to get a fake owl and put it near by - hopefully to ward off other birds of prey.
The second we got home to find the back door had somehow come off - we think from a persistant bear which then got two of our chicks. A solution for this is to bungee the back door - we have a tarp hanging over the back to give under the coop some shade and to add an extra layer of water proofing. This being said, we know of two people who have had their coops destroyed a total of three times from bear attacks so the omlet is performing relatively well.
He would return in 1992, with his third solo album The Predator. Cube, along with longtime collaborators DJ Pooh (who I will forever remember as Red, getting knocked the fuck out by Deebo in Friday), Bobcat and Sir Jinx would handle the bulk of the production duties on the album, with DJ Muggs contributing a few tracks as well. The album was released on the heels of the Rodney King verdict and L.A. riots, and both subjects are touched upon quite a bit throughout The Predator.
Love from spain and thank you for this reminisce moments ( and sorry for my bad english ). I love 88-92 ice cube. The king of rap at that moment to me. Maybe i like more death certificate or even amerikkkas most wanted but the predator is a very solid album. No doubt about the greates hit on this , it was a good day sounds so good like the first time i hear it. 24 years later i enjoy more and more who got the camera one of the sickest intrumental ever. Thanks for your work man.
Fish size, both in length and weight, provides quantitative information on fish stocks that are cornerstones for fishery research and stock assessment (Hilborn & Walters, 1992; Anderson & Neumann, 1996). Length-weight relationships (LWRs) provide information on the well-being and the somatic growth of fishes by assessing the condition factor and the allometric index, respectively (Froese, 2006).
All species mentioned above are top predators in pelagic food webs and, therefore, of potential ecological significance as keystone predators in the ecosystem context (Kitchell et al., 2006; Sala, 2006). In the modern understanding of aquatic ecosystems, shaped by concepts such as energy flow, food webs and trophic levels (Kemp & Boynton, 2004), LWRs may be useful to evaluate the extent to which body size explains variations among individuals in addition to foraging strategies, which contribute to our theoretical understanding of the implications of size-structured interactions for fish community dynamics (Costa, 2009; Juanes, 2016).
Also, there is a need to increase the biological information available at a regional level for these species based on a new understanding of the spatial dynamics and population structure, as well as the uncertainty about the population structure of these species in the Pacific Ocean (Diaz-Jaimes et al., 2006; Tripp-Valdez et al., 2010; Purcell & Edmands, 2011; Chang & Maunder, 2012; Schaefer et al., 2014; Lu et al., 2015; Su et al., 2015). This study provides the length-weight relationship (LWR) for striped marlin, Pacific blue marlin, sailfish, dolphinfish, and yellowfin tuna for a northern area of the Eastern Pacific Ocean (EPO). This contributes to a better spatial representation of the demographic characteristics of top predators inhabiting the Pacific basin, where the environmental spatial heterogeneity is recognized, particularly in the EPO (Fiedler & Talley, 2006; Pennington et al., 2006), potentially affecting process rates (e.g., latitudinal variation in somatic growth rate) and, ultimately, population dynamics.
Data were obtained from monitoring surveys conducted from 1990 to 2015 at Cabo San Lucas, Baja California Sur, by two research institutions (Centro Regional de Investigacin Pesquera and Centro Interdisciplinario de Ciencias Marinas). Surveys were performed consistently over three consecutive days of each month for recording biological information. Total weight (W), length (L) and sex were recorded for each specimen sampled. The eye-fork length was measured for striped marlin, Pacific blue marlin and sailfish, and fork-length for dolphinfish and yellowfin tuna. Sex was determined based on the macroscopic observation of gonads. Since yellowfin tuna does not present external sexual dimorphism and it was not possible to dissect them because they lose their commercial value, specimens were not sexed. Total weight was measured to the nearest 0.01 kg; length, to the nearest 0.1 cm.
The length-weight relationship W = a Lb was fit to the size attributes of fish, where W is weight (g) and L is length (cm). Parameters a and b were estimated by a nonlinear least-square regression method (Gauss-Newton algorithm). Confidence intervals for the model parameters are calculated by the confint.nls function from the MASS package as described in Venables & Ripley (2002). The degree of association between W and L was evaluated by the coefficient of determination (R2).
For sailfish, no significant differences in b-values were found between sexes (P > 0.05); consequently, data for both sexes were pooled for calculating LWR (Table 1). For striped marlin and dolphinfish, although significant differences were observed in b-values between sexes (P The relationships estimated for males and females of striped marlin showed significant differences, but not for sailfish. These billfish species, as well as all others included in the family Istiophoridae, are dioecious (separate sexes) and none of them are known to display sexual dimorphism or dichromatism, but females of many species reach a larger size than males (Nakamura, 1985). Sex-specific differences in size-atage are reported by many scientists (e.g., Kopf et al., 2011 for striped marlin; Ramrez-Prez et al., 2011 for sailfish; Shimose et al., 2015 for blue marlin), and are also reflected in the weight-length relationship. Thus, females not only grow to attain a greater length than males, but are proportionally heavier at the same length (Skillman & Yong, 1974). In FishBase (Froese & Pauly, 2016), LWR parameters a and b are shown for unsexed (pooled sexes) Pacific blue marlin. This is the first time these parameters are reported for females separately.
The LWR parameters a and b assessed may be considered as representative for these species in the study area, since the data were collected over a period of 26 years. Accordingly, these parameters likely reflect the well-being and somatic growth of the fish species in this period, which are potentially affected by the inter-annual environmental variability of the water masses interacting in the area (Fiedler, 2002; Bograd & Lynn, 2003). In FishBase (Froese & Pauly, 2016), LWR parameters were documented from references that derived the estimations from data gathered over particular years and are available for all species analyzed in this study; however, there are no records for the Pacific blue marlin and yellowfin tuna from waters off Baja California Sur.
The new information provided here may help to elucidate if fish from this region may exhibit differences compared to other regions inhabited by these species across the Pacific basin, hence improving the understanding of a putative population structure for any of these species and their underlying spatial dynamics (Begg, 2005). There is uncertainty about the population structure of the striped marlin in the Pacific Ocean (Purcell & Edmands, 2011; Su et al., 2015), as well as of the sailfish in the North Pacific Ocean (Lu et al., 2015), and for the dolphinfish in the EPO (Diaz-Jaimes et al., 2006; Tripp-Valdez et al., 2010; Chang & Maunder, 2012). With regard to yellowfin tuna, recent catch-and-release studies have indicated restricted movements, low dispersion levels, and fidelity of this species in waters surrounding our study area (Schaefer et al., 2014). Concerning the Pacific blue marlin, our results only for females are in agreement with previous reports about a segregation by sex for this region (Ortega-Garcia et al., 2006), which has been explained by sexual differences in the migration pattern related to spawning and feeding (Shimose et al., 2012). Differences in biological traits among groups of fish have long been used as a basis for the identification of fish stocks because of the relative ease of assessing these parameters and their dual functionality as input into fisheries stock assessment and management strategies (Begg, 2005). Thus, although information on the well-being and somatic growth of the fish species studied in waters off Baja California Sur is provided herein, the identification of each species' population structure is an interdis-ciplinary task that involves the use of various methods offering supplementary perspectives on population structure (Cadrin et al., 2005).
